00:00:53
Next item under recognition, the drinking water and wastewater professionals.
00:00:58
Bill?
Bill Mawyer
Executive Director
00:00:59
This is for you, Mr. Chairman, but it is a recognition by the governor.
00:01:04
Do you have that there?
Mike Gaffney
Chair, Rivanna Water & Sewer Authority
00:01:05
Yes.
00:01:06
Yeah.
00:01:07
Do we want to read the governor's recognition and then also the resolution?
00:01:14
Just the recognition.
00:01:15
Okay.
00:01:16
Yeah.
00:01:18
By virtue of the authority vested by the Constitution and Governor of the Commonwealth of Virginia, there is hereby officially recognized the Drinking Water and Wastewater Professionals Day.
00:01:30
Whereas the health, safety, and well-being of all Virginians is of utmost importance to the prosperity and livelihood of our Commonwealth's families and communities.
00:01:41
and whereas without reliable drinking water and wastewater treatment, the United States would suffer thousands of deaths each year due to waterborne diseases and whereas conscientious regulation and operation of both public and private drinking water treatment plants and distribution systems helps prevent contamination and other avoidable incidents that
00:02:05
threatened the health and wellbeing of Virginia's more than 8.6 million residents.
00:02:12
And whereas the Commonwealth produces an average of more than 817 million gallons of wastewater each day, the proper treatment of which protects the ecological health of Virginia's surface waters, such as the James and Potomac Rivers and the Chesapeake Bay.
00:02:29
and whereas thousands of water and wastewater industry professionals in the Commonwealth's public and private sectors dedicate their careers to keeping drinking water and treated wastewater clean and free of substances harmful to both humans and the environment and whereas the Virginia General Assembly passed House Joint Resolution 88 in 2016 designating June 30th as Drinking Water and Wastewater Professionals Day in Virginia.
00:02:59
Now, therefore, I, Glenn Youngkin, do hereby recognize June 30th, 2023 as Drinking Water and Wastewater Professionals Day in our Commonwealth of Virginia.
00:03:11
And I call this observance to the attention of all our citizens.
00:03:17
Thank you.
00:03:18
Do we have the resolution, Deborah?
SPEAKER_05
00:03:23
Yeah.
Bill Mawyer
Executive Director
00:03:26
If we could have a motion and a second to adopt the resolution recognized on June 30th as Strength of Water Wastework Professionals Day, that would be nice.
SPEAKER_05
00:03:37
So moved.
00:03:38
Second.
Mike Gaffney
Chair, Rivanna Water & Sewer Authority
00:03:39
OK, we have a motion and a second.
00:03:41
All in favor?
00:03:42
Aye.
00:03:43
Opposed?
00:03:44
OK.
00:03:47
Next item is the executive director's report.
00:03:50
Yes, sir.
00:03:51
Thank you.
Bill Mawyer
Executive Director
00:03:52
Well, I want to start off by saying I'm just glad we are here today.
00:03:57
Because at 6pm last night, we weren't so certain that we were going to be able to have this meeting, because we didn't have any electric power in the building.
00:04:07
And we figured out, actually, we've had a circuit breaker that has tripped three times in the last five days, and it shuts this whole building down.
00:04:17
But our staff rallied around and we found a replacement breaker in North Carolina.
00:04:25
for a cost of $20,000.
00:04:26
And that manufacturer, the supplier, drove it here last night, two o'clock in the morning they got here.
00:04:33
And our staff at six went to work along with Pyramid Construction who's here and replaced the breaker.
00:04:40
So with engineering, maintenance, operations, IT, all had to rally around and get this put together.
00:04:48
But by shortly after seven this morning,
00:04:51
They had us back up in business.
00:04:53
Computers, everything.
00:04:54
Austin Marrs captained that process, so we appreciate Austin and his dad who is our maintenance director.
00:05:03
So they've had quite a team to get it going.
00:05:06
Scott, are you here?
00:05:07
Scott Schiller, Ram Rodden, and David Tungate.
00:05:10
So it was quite a team effort last night and this morning to get us back up.
00:05:15
So coincidentally, the 5KV electrical CIP project we have going on here is supposed to replace that breaker, but they don't have a new one yet.
00:05:26
It's on order.
00:05:27
So we got one from North Carolina, and now we'll have a backup.
00:05:31
When they get the new one, we'll have a backup.
00:05:33
So all's well that ends well, but it's quite a process.
00:05:37
So we're thankful we're here.
00:05:40
I also want to recognize Drew Prothero, who's a wastewater operator class three.
00:05:47
He passed his state license to attain that level.
00:05:52
Drew's been with us about a year and he's a graduate of James Madison University.
00:05:56
So we're pleased that he's pursued his license increase and obtained it.
00:06:02
June is national safety month.
00:06:06
and so we're focusing on that.
00:06:09
Our safety manager has a program and each week there's been a theme from emergency preparedness to slips, trips and calls, heat related issues and hazard recognition.
00:06:21
As part of our leadership training, our David Tungate attended a local government advisory council tabletop exercise on PFAS, I think with Ms. Malek not long ago.
00:06:33
and our Director of Engineering and Maintenance, Jennifer Whitaker is gonna participate in the Charlottesville Chamber of Commerce's Leadership Lab Program that's gonna start I think in January for nine months, maybe September for nine months.
00:06:49
In addition, we have a team building event here in our parking lot where we try to get together with all of our staff and get to know each other better.
00:06:57
And one of the things that we have an opportunity to do is to introduce the five interns that we have for this summer.
00:07:04
And so I'll invite all five of them to come forward please and introduce yourself to the board and tell them where you go to school and what you're helping us with this summer.
Mike Gaffney
Chair, Rivanna Water & Sewer Authority
00:07:15
I'm Owen White.
00:07:16
I'm the chemistry, the chemist intern.
00:07:20
I'm from University of Mary Washington.
00:07:22
I'm helping check the water quality, do cold forms, do all that.
SPEAKER_05
00:07:27
Right.
00:07:28
Thank you.
SPEAKER_08
00:07:30
I'm Katie Shelton.
00:07:31
I'm Verizon's fourth year at UVA studying environmental science, and I'm the water resources intern sampling water quality.
SPEAKER_09
00:07:39
All right.
00:07:40
Thank you.
00:07:40
Hi, I'm Niana Kazarowski.
00:07:42
I go to UVA.
00:07:43
I'm going to be a third year.
00:07:44
I'm the sustainability intern, so I'm doing greenhouse gas baseline calculations and research on electric vehicles.
00:07:52
Thank you.
SPEAKER_00
00:07:53
Hi, I'm Caleb Berle.
00:07:54
I'm going to be a second year at Minnesota North College, and I'm a wastewater operation attorney.
SPEAKER_01
00:08:03
I'm Logan Oldsop.
00:08:04
I go to UVA and I'm an engineering intern here.
00:08:07
I've been working on revising our emergency action plans for our days.
Bill Mawyer
Executive Director
00:08:13
Great, great.
00:08:14
So we have a terrific crew this year.
00:08:16
We appreciate them joining us and hope they have a positive experience here and maybe we'll find a career with this one day.
00:08:23
So thank you all for coming.
00:08:27
Well, we,
00:08:28
Had teed up a discussion about the drought concerns.
00:08:34
Fortunately, when we did that, it started raining.
00:08:38
So maybe that's the practice we should continue.
00:08:41
But the data shows that we are 14 inches low over the last 29 months, which is about 14% below normal.
00:08:51
And next slide there, Deborah.
00:08:55
So this is a slide that shows how
00:08:59
about a condition we were in a week ago.
00:09:02
So let me see.
SPEAKER_05
00:09:03
Can I use this point?
Bill Mawyer
Executive Director
00:09:06
Okay.
00:09:07
So what this graph shows, this dotted line here, that's the normal flow of the South Fork of the Rivanna River below the dam.
00:09:15
We have a gauge or USGS has a gauge there and they monitor the flow.
00:09:20
Last year is this graph right here.
00:09:24
So last year, basically we were flowing at normal levels
00:09:28
This was the flow we were seeing June 10th through June 16th, which if you look over here it says it was about 80% below normal.
00:09:38
We were getting a big concern that with the last 29 months we were not in good condition.
00:09:46
So the flow say in June of 2022 was 162 million gallons per day, but in June of 2023, it was 27 million gallons a day, a significant decrease.
00:09:59
However, the rest of the story is it started raining and from
00:10:05
June 20th through the 26th, now you see the flow in the same river from the same gauge has increased significantly, gone above the average, gone above last year, but you do see it starts dropping pretty quickly.
00:10:22
So we would not say the drought concern has passed, but
00:10:25
It's been mitigated for a while.
00:10:29
And you know, we talk a lot about the pipeline from the Rivanna to the Ragged Mountain reservoirs and being able to capture and pipe and pump water within from Rivanna to Ragged.
00:10:42
And you see here on this chart recently, we had 200 million gallons going in the Rivanna River below the dam and on the 22nd.
00:10:52
400 million gallons on June 24th.
00:10:56
So that's some of the water we're trying to capture with this new pipeline and pump it over to Ragged to help keep Ragged full.
00:11:04
So, okay, thank you.
00:11:07
Any questions about that point?
Ann Mallek
Member, Rivanna Water & Sewer Authority
00:11:09
Well, yes, I'm glad to see this graph because that wasn't in my packet.
00:11:15
I have pulled up my little trusty measurements, which I started doing
00:11:21
back in 2002 when things were really, really bad.
00:11:25
But still, when you take that multi-year approach, we're still not out of the woods by any means.
00:11:31
I mean, if you're supposed to get 36 to 40 inches and you only get 16 for a couple of years, you're in deep duty.
00:11:38
I do not want to have anybody feel complacent about that.
00:11:41
That's one week and this could be.
00:11:43
And we only got seven tents last night.
00:11:45
Maybe other people got a whole lot more, but it's so spotty about where the water is and
00:11:51
if we can hold onto it and not have it go racing down over the dam.
Bill Mawyer
Executive Director
00:11:56
That's the theory of reservoirs.
00:11:59
Yeah, to capture it and hold it, not let it go out of our system and it's gone.
00:12:03
Yeah, so our water resources manager, Andrea Bowles, pulled this up for us today.
00:12:09
So she keeps us up to date on this.
Mike Gaffney
Chair, Rivanna Water & Sewer Authority
00:12:11
Any input yet on the water table?
00:12:15
No, we have.
Andrea Bowles
Water Resources Manager
00:12:16
The data is still containing that groundwater is still in the water
00:12:21
How granular is their reading?
Ann Mallek
Member, Rivanna Water & Sewer Authority
00:12:36
Because I know people in the northwest part of Albemarle are very angry about the fact that they're telling us that this is no big deal.
00:12:43
Green County's in the serious thing as we are not.
Andrea Bowles
Water Resources Manager
00:12:46
Yeah, so they meet.
00:12:48
I haven't figured out the regularity with which they meet, but I am in touch with Trevor Lawson, who is the contact with them.
00:12:55
And if you go to the DEQ drought watch web page, you'll see his contact information.
00:13:01
And in the upper right hand corner of that page, there is a drought monitoring task force report.
00:13:07
So the last time they met was June 15th.
00:13:10
And that report, their summary was not posted as of yesterday.
00:13:14
They sent it to me yesterday because I asked for it, but they are meeting again this Thursday.
00:13:18
So I think right now it's about every two weeks.
00:13:21
And I'm trying to stay in touch with them pretty regularly to see, let them, give them feedback on what's happening with us as well.
Ann Mallek
Member, Rivanna Water & Sewer Authority
00:13:28
But are they measuring rainfall in more than one or two places?
Andrea Bowles
Water Resources Manager
00:13:31
They do, but for our region, so they look at four different, they look at, they bring together a whole lot of professionals to talk about, right?
00:13:40
Precipitation, talk about geology, groundwater, et cetera, et cetera.
00:13:44
and then they have those four different factors that they evaluate.
00:13:49
They evaluate groundwater, precipitation, stream flow, reservoir levels, groundwater, stream flow, precipitation, and reservoir levels.
00:14:04
For our region, they're using Lake Moobong.
00:14:08
So that's
00:14:09
We look at our RS4 level.
00:14:11
So they only use like one point in the whole region, which is the Middle James.
00:14:18
So that's why we keep an eye on all of our RS4s and compare all that data and look back at it.
00:14:23
So it's a good indicator.
00:14:24
It's a good thing to go to.
00:14:25
And then you take that and then you also look at our data.
SPEAKER_05
00:14:30
You're welcome.
00:14:30
Thank you, Andrea.
00:14:34
Okay, so
Bill Mawyer
Executive Director
00:14:37
In our infrastructure priority of a strategic plan, major projects, we have had success with the University Foundation and come to agreement on
00:14:51
The location and cost of easements and a property purchase on the Westover and Foxhaven properties.
00:14:59
And those documents are in their hands for signature now.
00:15:03
So we expect to have a signing party very soon with them and get that put behind us.
00:15:08
So that would be good news.
00:15:09
So that's the easement from Rivanna Reservoir to Ragged Mountain Reservoir.
00:15:15
And we're purchasing 1.1 acres
00:15:18
and over by Reservoir Road to build the pump station.
00:15:22
That'll pump from Rivanna to Ragged and Ragged back to South Rivanna treatment plant.
00:15:27
It also would pump from Ragged to Observatory treatment plant.
00:15:31
So it's a multipurpose pump station there.
00:15:35
So we're thrilled about that.
00:15:38
I will continue to work with the university around the Fontaine area.
00:15:42
They believe they located a cemetery and that was conflicting with some of the development plans there, including our waterline location.
00:15:51
So they and we are trying to work together and get that resolved.
00:15:56
The central waterline design is going well.
00:15:59
We expect to have the 60% design plans in this month.
00:16:04
And we'll be coordinating with the city and the service authority to review those plans and have comments.
00:16:10
Still projecting construction to start around next June.
00:16:14
on that project.
00:16:15
At the Allen Farm Lane Bridge repairs, as it's a Buck Mountain property, repairs started yesterday on the concrete piers that are in the stream, and we expect them, weather permitting, that they'll be completed by the end of next week.
00:16:29
So that's good news.
00:16:31
We also participated last week for a part of three days in an EPA drinking water contamination drill with the service authority and city utility staff.
00:16:43
And so the scenario was that there was a leaking chemical tanker that leaked into the Rivanna Reservoir.
00:16:50
and the chemical got into the Rivanna water treatment plant and then the distribution system.
00:16:55
And it was realized that there was a problem when people started showing up sick at the hospitals and healthcare facilities.
00:17:02
And so it was a good learning experience to walk and work through our processes of how we as utilities and the three utilities together would work with a scenario like that.
00:17:13
So that was good and EPA sponsored it.
00:17:17
They were there, they had a consultant there with us.
00:17:21
Further, to expand and enlighten our specialists from the FBI, we invited them to come here and they did earlier this month to take a look at our cybersecurity system, to familiarize them with our facilities so that if we ever had some sort of event here,
00:17:40
It wouldn't be the first time that they had been here.
00:17:43
And so I think there's a local agent who lives in Crozet who attended along with their critical infrastructure experts.
00:17:51
So that was a good review that we had with them and meeting and they were impressed with our cybersecurity technology that our staff has put in place.
00:18:01
So that was very a part.
00:18:05
I spoke to the Land Use and Environmental Planning Committee about our community's water supply plan and secondly about our South Rivanna River Crossing project over the last month or so.
00:18:18
And I also went to Ms. McKiel's Hydraulic Area Community Advisory Committee meeting and talked about the community water supply plan with that group one night.
00:18:31
So that was good to get our message out there.
00:18:34
And that's my report, Mr. Chairman.
Mike Gaffney
Chair, Rivanna Water & Sewer Authority
00:18:36
Thank you.
00:18:38
Thank you, Bill.
SPEAKER_05
00:18:38
Any comments or questions for Bill?
David Tungate
Director of Operations & Environmental Services
00:18:41
So Bill, the line here from South Fork Rivanna, the black line is obtained.
Bill Mawyer
Executive Director
00:18:53
He's been obtained.
00:18:54
The blues sounds like it's now ready to turn black.
00:18:59
We have agreement on location and all the terms, including the conversation with the Foundation.
00:19:07
And so as soon as we get signed documents, this blue section and this blue section will have been obtained.
Mike Gaffney
Chair, Rivanna Water & Sewer Authority
00:19:15
And the only pending is right here at Fontaine Observatory.
Bill Mawyer
Executive Director
00:19:22
That's what we understand from the University Architects Office.
00:19:30
Good news, after six years working on it, we're almost at the end.
Mike Gaffney
Chair, Rivanna Water & Sewer Authority
00:19:35
And I apologize for being late.
00:19:37
You almost can't get from UVA over here this time of day, particularly with all the construction.
SPEAKER_01
00:19:43
UVA's construction.
Mike Gaffney
Chair, Rivanna Water & Sewer Authority
00:19:46
Not ours.
00:19:48
Not yet.
SPEAKER_05
00:19:49
Not yet.
Mike Gaffney
Chair, Rivanna Water & Sewer Authority
00:19:50
Next year.
00:19:53
OK, next item on the agenda are the items from the public.
00:19:57
So we'll open up the meeting for public comment.
00:20:00
Do we have any members in the audience who would like to speak at this time?
00:20:07
Do we have anyone online who would like to speak?
SPEAKER_00
00:20:11
No, sir.
00:20:11
None at this time.
Mike Gaffney
Chair, Rivanna Water & Sewer Authority
00:20:13
Okay.
00:20:14
We will close the items from the public.
00:20:16
I know there's no responses to those comments.
00:20:19
Move on to the consent agenda.
SPEAKER_05
00:20:21
Are there any items on the consent agenda board members would like to pull for comments or questions?
Mike Gaffney
Chair, Rivanna Water & Sewer Authority
00:20:33
All right, do we have a motion and a second to approve the consent agenda?
SPEAKER_05
00:20:36
Second.
Mike Gaffney
Chair, Rivanna Water & Sewer Authority
00:20:37
Motion and a second.
00:20:38
All in favor?
00:20:40
Aye.
00:20:40
Opposed?
00:20:41
Motion varies.
00:20:44
Next item under other business is the presentation of the water treatment facilities.
00:20:51
Dave?
David Tungate
Director of Operations & Environmental Services
00:20:52
Great.
00:20:54
Thank you, Steve.
00:20:54
It's a timely presentation given the fact that we had water and wastewater protection on the week of Friday.
00:21:00
Before I get started and talk about the way the water treatment plans, I want to introduce Daniel Campbell.
00:21:05
He's a water manager.
00:21:06
He's the leader of our water department and one of the 27 employees that works for the water department getting water out to our customers.
00:21:15
I have some really cool handouts here we're going to talk about.
SPEAKER_05
00:21:18
So go ahead.
David Tungate
Director of Operations & Environmental Services
00:21:22
So again, a map of our water system.
00:21:26
Many of you have seen it before up at the upper left-hand corner, the Sugar Hollow Reservoir, which has been a topic of some conversation lately, and the discharge from the South Rivanna Reservoir flows to the Mormons, which joins the Meacham's to form the South Rivanna River, which of course makes the South Rivanna Reservoir.
00:21:46
And currently there is a pipeline
00:21:49
that can transfer water from Sugar Hollow to Ragged Mountain, but in the future as the pipeline connecting South Fork to Ragged Mountain, just put it in place, that pipeline will be out of service.
00:22:01
We have a reservoir, Beaver Creek, Inc. pros-a that feeds the treatment plant, pros-a water treatment plant, which supplies just the pros-a area.
00:22:09
Going down to the left corner here we have the Redhill Treatment Plant, which is a small groundwater system in the Redhill area which serves nine or 10 customers in the school in Redhill.
00:22:19
So it's our only groundwater system that we maintain.
00:22:23
We're going to be talking about the South Rivanna plant, the Observatory Treatment Plant on the grounds of the UVA,
00:22:29
and our North Rivanna treatment plant, which is north on 29, just south of the NGIC facility.
00:22:37
And those three treatment plants, Observatory South and North Rivanna, form what we call our urban water system, which feeds the city of Charlottesville and the urban ring around Charlottesville.
00:22:48
At the far southern end of the county, we have a Scottsville water treatment plant that takes water from Totterre Creek and Totterre Creek Reservoir.
00:22:56
So we essentially have two sources down in Scottsville, one from the creek and one from the message.
00:23:04
Again, some aerial pictures of our facility of the upper left hand corner of South Rivanna treatment plant.
00:23:09
We took this picture two weeks ago courtesy of Rob Woodside and our IT department.
00:23:14
We have a drone.
00:23:16
So the South Rivanna picture was taken about two weeks ago, obviously before it rained, as you can tell.
00:23:21
And then the observatory treatment plant in the center.
00:23:23
This is on UVA grounds.
00:23:25
This also was taken two weeks ago.
00:23:27
And you can see how we are on Observatory Hill with, there's the football stadium in the upper right hand corner and then these are some UVA dorms.
00:23:38
So we are sort of right in the middle of campus if you've not been there.
00:23:41
Our North event treatment plant located on the north side of town and then our Crozet facility in Crozet.
00:23:48
and then our Redhill facility, brown water facility down near the Redhill area and then our Scott Schiller water treatment.
00:24:00
So we talk about permanent capacity and production.
00:24:03
So we have a permanent capacity of South Rivanna of 12 million gallons a day.
00:24:07
That's an MGD stands for million gallons a day.
00:24:10
But the right hand column there talks about our average production.
00:24:14
Your car can go 150 miles an hour, but you don't drive it 150 miles an hour.
00:24:17
So the South Nevada plant can produce up to 12 million gallons a day.
00:24:21
In 2022, we averaged just under 8 million gallons today.
00:24:24
The observatory plant currently is permitted for 7.7 million gallons a day.
00:24:29
When the upgrade is over, we'll be able to do 10 million gallons, but it still says 7.7 because the product isn't done yet.
00:24:36
Our average day there was only 900,000 gallons a day.
00:24:40
Our North Urbana facility can take up to 2 million gallons a day from the river to the plant and our average production there was 0.43 million gallons.
00:24:52
So again, our urban total permanent capacity is over 21 and a half million gallons a day, but then our average production for the year was only about 0.32.
00:25:02
permanent capacity at Crozet again at 1.6 you can see our differences that have been found at all.
00:25:11
Scottsville being the smallest surface water system were permitted for 0.25 million gallons a day, 250,000 gallons, but our average production in 2022 is only 60,000 gallons.
00:25:25
Any questions about that table?
Ann Mallek
Member, Rivanna Water & Sewer Authority
00:25:28
Is there a stream release requirement for the North Fork since that's a run of the river?
00:25:35
Withdrawal.
00:25:36
But when it gets loaded, you just stop taking it in, I guess, because it's... We were keeping track of that.
David Tungate
Director of Operations & Environmental Services
00:25:46
Even a week ago, Monday the 19th, we were keeping track of that.
00:25:50
We were taking daily pictures.
00:25:51
Of course, the USGS has a gauging station upstream of our intake, and we were keeping track.
00:25:57
As Bill showed you, the South Fork gauging station, we had something to do with putting that in.
00:26:02
below the South Fork and there's one on North Fork above our intake so we'll check for that also there's a whole series of those that we were all very very attentive to in the previous two weeks and then it happened to rain so thank our stars for that thank you so we talk about service water treatment plant there are six steps to a conventional or five steps to a conventional service water treatment plant you take the water from the source
00:26:29
Coagulated, flocculated, sedimentation, filtration and disinfection.
00:26:34
So everyone will be able to wild their families tonight at dinner.
00:26:37
So coagulation, flocculation, sedimentation, filtration and disinfection.
00:26:41
So we have pictures.
00:26:44
So this is a picture from South Fork Dam.
00:26:47
thinking about two weeks ago.
00:26:48
And again, this is when the flow was still low.
00:26:50
We can see the water looks relatively clean.
00:26:53
This would be a day when the water was being transferred to Ragged Mountain.
00:27:00
The next picture taken at the same place a couple of years before, you can see that's what it can look like.
00:27:05
This was actually taken in May of 2018.
00:27:08
We had those 12 inches of rain in Ivy over the course of less than a day.
00:27:13
But again, the water quality can change, the source water quality.
00:27:17
And what's important is that our customers, our users, don't notice that.
00:27:20
Daniel and his water operations staff notice that the source water changes, but our customers don't notice that.
00:27:29
So this is a photo again taken a couple weeks ago at South Rivanna.
00:27:35
We have the six sedimentation basins and we're going to talk about that.
00:27:38
But again, sedimentation is one of the steps in conventional surface water treatment.
00:27:43
We have a new filtration.
00:27:45
We've added two new filters in the filtration plant itself.
00:27:48
We're going to show a picture of those later.
00:27:51
Water Administration Building, our Water Administration staff is all housed in one place now.
00:27:57
We have our sodium hypochlorite building where we store 27,000 gallons of sodium hypochlorite which we use to disinfect.
00:28:05
Some of our alum and fluoride are stored in this building.
00:28:10
That's a new building that was added during the South Savannah upgrade.
00:28:15
We have our GAC building, which houses eight of our GAC contactors.
00:28:20
And then the last but not least, we have filter press there.
00:28:23
So we settle out solids during the process.
00:28:27
We need to do something with those solids.
00:28:28
We aren't connected to sewer at South Rivanna, so we can process that sludge.
00:28:34
We water the sludge in a filter press, we bring those solids back here for processing.
00:28:40
That's out there.
00:28:42
So some of the water chemicals that we use, aluminum sulfate we use as a coagulant that just brings the particles together and helps them settle.
00:28:50
We use a liquid liner product now.
00:28:53
It really just looks like milk.
00:28:55
We use that for pH adjustment because the aluminum sulfate is an acid.
00:29:00
It drives the pH down.
00:29:01
They have to bring it back up again.
00:29:03
so that the coagulation process works.
00:29:05
Sodium hypochlorite, we use that for disinfection of the water, and then to oxidize any iron and manganese that's in the water.
00:29:12
Orthophosphate, this is our corrosion control that we use in our piping.
00:29:16
Again, this is the product.
00:29:17
Ortho corrosion inhibitor is what Flint, Michigan failed to do.
00:29:20
We talked a lot about Flint, Michigan.
00:29:22
Did not add orthophosphate or corrosion to the product to the water.
00:29:26
We were feeding an orthophosphate product.
00:29:28
And then last but not least, we do add hydrofluorosilic acid.
00:29:32
for mental health, without drinking.
00:29:37
So this is a photo of one of our operators, water operators at our South Rivanna raw water pump station.
00:29:43
Again, you can see the size and the scale of these raw pumps.
00:29:46
So these are what's taking water out of the reservoir, out of the intake structure, and pumping it up to the South Rivanna plant.
00:29:55
And this box, this corner of the box here, this is actually our intake itself.
00:30:00
And we have gates that we open at the five foot, 10 foot, and 15 foot depth.
00:30:05
in the reservoir.
00:30:07
Go ahead.
00:30:11
So we talk about bringing water up from the reservoir and we add our chemicals to it.
00:30:17
And then we flocculate these particles.
00:30:19
And so if you can see in that picture there, the cloud, those are our particles that have come together.
00:30:24
They stick together and they enter our sedimentation basins and the sedimentation basins are designed so that the flow, the velocity is low.
00:30:32
The flocculated particles come together and they settle out from the sedimentation.
00:30:37
That's the purpose.
00:30:38
And so that's what this cloud is here.
00:30:40
This is a particle that are coagulated, flocculated together.
00:30:46
So frequently the chemical doses can be somewhat tricky at times when it rains, the temperature drops in the water.
00:30:57
and for water temperature changes that need more chemicals, different chemicals, different doses.
00:31:02
And so what we frequently do with the water treatment plant, what you're seeing here is we took raw water and these are five different jars, six different jars of raw water and we add chemicals.
00:31:13
So we simulate what happens in the water treatment plant, different doses in each jar.
00:31:18
And then on the right, this is what after
00:31:21
We run the tests to help determine what dose would work best for the water so it's really descriptive right because you can see that the water on the left the solids are in solution the water is dark the water is cloudy then on the right hand side after we do add the chemicals you can see how it's settling
00:31:41
Again, this shows what happens in the sedimentation base.
00:31:45
It also settles out.
00:31:46
And then I have some water here.
00:31:48
I'll get it showed around.
00:31:49
Daniel's nice enough to give it to us.
00:31:51
So the first one I'm giving Bill, this is raw water.
00:31:54
So that water has not been treated chemically.
00:31:56
And then the second one is filtered water.
00:31:58
It's really descriptive.
00:31:59
You hold it up to a white piece of paper just to show kind of what we're doing at the plant, how important it is that we're feeding the chemicals at the right dose at the right time when we get our pH.
00:32:13
So we talked about the raw water, we plopped it, we settled it inside basins.
00:32:19
The next step is the gravity filters.
00:32:22
And so you can see six in succession here, the two closest to them, where the picture was taken of the two newer ones that were added during this upgrade.
00:32:30
And we have six in gravity filters in south Rivanna.
00:32:35
So I've shown this slide for crypto and charity.
00:32:38
And those of you that I have talked about this before,
00:32:41
On the left is giardia that is handled with oxidation, so it's our disinfectant or sodium nitrochloride.
00:32:50
On the right is cryptosporidium.
00:32:52
They're in cysts, and so they have to be filtered out.
00:32:56
So the two main actors, the two bad guys that we're trying to get out with the water is crypto and giardia.
00:33:04
And then how do we know that works?
00:33:06
Well, we have filter turbidimeters.
00:33:08
And these are on each of our filters at all of our water treatment plants.
00:33:13
And it takes samples.
00:33:14
It doesn't take a sample every minute.
00:33:16
It doesn't take a sample every 30 seconds.
00:33:17
It takes a continuous sample.
00:33:19
It's hard to see, but this is water that's flowing out of this turbidimeter.
00:33:23
There's a laser that shoots in there.
00:33:24
It measures the refractivity.
00:33:26
It measures
00:33:26
There's how the light is refracted or scattered as it goes through the water and it's a continuous reading.
00:33:32
So it's read on our SCADA screens continuously.
00:33:38
So we know exactly what's going on all the time, but as recorded.
00:33:41
So online instruments, SCADA instruments, instruments that read out remotely on our screens are only as good as they're calibrated.
00:33:50
So every shift, the water treatment plants are run, the South Havana treatment plant is run 24-7 right now.
00:33:57
And so every shift, every 12-hour shift, they have to calibrate
00:34:01
The online instruments, they confirm that the numbers they're seeing are what they're seeing on the benchtop.
00:34:07
So that's why I show it's very important that the information that we're processing is correct.
00:34:15
And again, last but not least, these are finished water pumps at South Rivanna.
00:34:19
These are, once we treated the water, these are the pumps that deliver it into the distribution system.
00:34:26
And then my other two pictures, so we've talked about powder activated carbon and
00:34:31
Granler, we're going to talk more about those.
00:34:39
It's like black flour.
00:34:42
It is a one-time process.
00:34:43
We feed it one time in the plant and it is one time passed through.
00:34:48
And it's on the order of a dollar a pound.
00:34:51
And the granular product, which is in the other vial, looks like black grape nuts.
00:34:55
And that stuff is about a dollar and a half a pound.
00:34:57
And that's what sits in the big carbon vessels that we have at all our museums.
00:35:02
The granular carbon is too what you see in Brita filters that you have in your refrigerator filters and whatnot.
00:35:10
These two kinds.
00:35:11
So our activated carbon, again, as I said, it's fed in the process.
00:35:15
So this is at South Rivanna.
00:35:18
We feed it in the mixing basin.
00:35:20
In this picture I've used a couple of times.
00:35:22
As you can see, the water on the left is dark.
00:35:24
This was the day we had some rain.
00:35:26
And then you can see the water on the right.
00:35:28
This on the left, this is
00:35:33
from the reservoir.
00:35:34
This is where we mix all our chemicals, the flocculators.
00:35:38
From the right-hand side here, these are sedimentation bases.
00:35:40
So the solids are settling out.
00:35:41
This picture tells a thousand words.
00:35:44
People like Daniel and I that have done this report, this is what it means.
00:35:46
It means that we're settling out the solids.
00:35:48
You don't see dark water on the left and clear water on the right.
00:35:53
That's good.
00:35:54
If they were the same, they would probably be working a little harder.
00:36:03
Yeah.
00:36:05
What we see here, this is another same employee.
00:36:08
He's pulling a water quality sample from one of our granular activated carbonic contactors, vessels we call it.
00:36:14
So just to give you the scale, they're about 26 feet tall, about six foot tall, individual.
00:36:20
Each one of these tanks has 40,000 pounds of the granular activated carbon product.
00:36:25
So they're big vessels.
00:36:28
It's a lot of money.
00:36:28
And we talk about that in our budgets, but that's what it looks like.
00:36:32
That's what they are.
00:36:35
So currently we have burning water activated carbon vessels or contactor that all of our surface water treatment plants right now.
00:36:45
So South Rivanna has eight contactors.
00:36:48
That's 320,000 pounds of JAC and 8 million gallons of their capacity.
00:36:53
So plants rated for 12, we have eight.
00:36:57
What that means is we can treat three quarters of the water if we need to through the JAC vessels in South.
00:37:03
Observatory.
00:37:05
We had two vessels.
00:37:07
We added four more in the project.
00:37:08
So there are six contactors at observatory, again with 240,000 pounds.
00:37:14
We have a project in Crozet.
00:37:18
We're going to add a contactor to the Crozet facility.
00:37:22
Contactor at Crozet, over 20,000 pounds of GAC.
00:37:27
So we have at the urban plants, we have 40,000 pound vessels, which are 26 feet tall.
00:37:34
At Crozet's plant, we have 20,000 pound absorbers and they're 22 feet tall.
00:37:39
And then in Scottsville, because it is such a smaller facility, we have two 6,000 pound contractors in Scottsville.
Bill Mawyer
Executive Director
00:37:47
And Redhill?
David Tungate
Director of Operations & Environmental Services
00:37:48
And Redhill doesn't have one now, but the project that's going to add the third vessel to CROS-A is going to also add a contractor to Redhill.
Mike Gaffney
Chair, Rivanna Water & Sewer Authority
00:37:56
Do you need it for well water?
David Tungate
Director of Operations & Environmental Services
00:37:58
It depends on what we've detected, if you had any contamination.
00:38:02
We don't show any contaminants at Redhill that would need to have granulated carbon at this point.
00:38:09
But in the future, it could be there.
00:38:11
And again, to maintain purity in our system, we're really important that we treat
00:38:14
the nine customers in Red Hill the same as the customers we've never seen.
Ann Mallek
Member, Rivanna Water & Sewer Authority
00:38:19
Is there ongoing testing of the plume from the old gas station of the building?
David Tungate
Director of Operations & Environmental Services
00:38:24
That I don't know.
00:38:25
I don't know.
00:38:25
We've talked to DEQ a couple of times.
00:38:27
I know that at times they did sample.
00:38:29
They sampled the sediment monitoring wells and had sampled some resonances.
00:38:34
As far as I know, they haven't asked ACSA to hook up other customers.
00:38:37
I believe there are stop boxes and service lines in the right of way for homes if they have a well, if their well is contaminated.
00:38:45
I don't know that.
00:38:49
This photo was again taken a couple weeks ago, different angle.
00:38:52
So the first shot we took at the observatory was sort of over the drones over the UVA water storage tanks.
00:38:58
And this this drone is more over the stadium essentially showing a picture again of
00:39:04
of what goes on and how we are just embedded in the UVA community.
00:39:08
Our filter building remained the same but we added, we renovated the filters so we have five new filters in this building.
00:39:17
These are two big backwash waste basins.
00:39:19
Our sedimentation basins, we have four.
00:39:22
The old plant had four.
00:39:23
We're going to two.
00:39:25
So we have four basins that could do 7.7 million gallon flow.
00:39:29
And now we're going to two sediment basins that can do 10 each.
00:39:32
So 20 mgd.
00:39:34
We added settled plates, plate settlers in there that could increase the capacity.
00:39:39
And then you can see if I need to click it one more time.
00:39:42
There's my cool arrow.
00:39:43
So this is showing the building extension that added four more GAC contractors.
Bill Mawyer
Executive Director
00:39:48
So those water storage tanks, that's basically like a buffer for the UVA, but you've got the rest of your water system is going other places.
David Tungate
Director of Operations & Environmental Services
00:40:03
Yes, the UVA, every, so we are at the bottom of
00:40:08
McCormick, Alderman Road, and McCormick.
00:40:10
There is an Alderman pump station.
00:40:13
We have half the pump station with Rivanna pumps and the other half is UVA's, UVA pumps.
00:40:18
UVA pumps pump to their system and the water that's not consumed goes to the old water storage station.
00:40:25
The UVA takes over a lot of ours.
00:40:30
So we talk about the testing, we talk about what we do and how we do it, but also we have to submit monthly reports.
00:40:36
Daniel was a licensed operator of the treatment facilities.
00:40:39
We submit monthly reports by the 10th of the month.
00:40:42
So July 10th, the June reports are due.
00:40:46
And this is the information that we have to give them, which is the volume of water we pumped in and out of the plants, the chemical dosages, the filter bar turbidity, which we showed you, the turbidimeter, the online and benchtop that we use,
00:40:58
We do total coliform sampling results for all four of our water systems.
00:41:13
That's Urban, Crozet, Scottsville, and Redhill.
00:41:16
And then any safe drinking water react data that we are collecting.
00:41:20
We actually don't
00:41:24
So, Water Department budget, we talked about this
00:41:47
$25 million is the operating budget, $13 million for debt service, roughly $3 million for central support, which is finance, IT, engineering, maintenance, lab services,
00:42:00
$2.5 million for water department salaries, $2 million for water treatment chemicals, $900,000 of it is for GAC.
00:42:10
And what you're seeing over here, this is a GAC delivery at Southward Air, Philadelphia.
00:42:17
We spent roughly $2 million treating the water, and roughly half of that is for graylands and carbon.
00:42:25
and then a million dollars for operations and maintenance and about $700,000 feet to and across.
00:42:31
Again, pumping water is very expensive when it comes to electricity.
00:42:35
So we produced 3.8 billion gallons of drinking water and at the cost of a penny per gallon.
00:42:42
Oh, any questions?
00:42:46
I'm sorry, I'm rolling right through this.
00:42:50
These are our staffing, our water department staffing.
00:42:53
We have 27 total staff.
00:42:56
We have nine operators at South Rivanna, including a water quality specialist that came on the screen somehow.
00:43:04
We have four operators at our
00:43:06
And it's important to note that these operators have to have licenses to run these plants.
00:43:12
You can't have, so South America is a class one facility.
00:43:15
When Bill talks every month about operators that have passed their license schemes, you have to have a class one operator on duty 24 seven when the plant is running, you have to have a class one operator there.
00:43:25
So class one is the highest operated class in Virginia.
00:43:33
So South Urbana Observatory are class one facilities.
00:43:36
North Urbana is a class two facility.
00:43:38
And Prose is a class two.
00:43:40
Scraptural is a class three.
00:43:41
And Red Hills is a class four facility.
00:43:45
So we have 22 water operators.
00:43:47
We have three relief operators.
00:43:49
What's that?
00:43:49
Well, these are operators that are a class one license, and they are essentially available if someone calls in sick of someone.
00:43:57
We need extra production, we need pros aid, we need extra staff.
00:44:01
These are people that we can call in.
00:44:03
I wouldn't say at a moment's notice, right, Daniel, but almost at a moment's notice.
SPEAKER_05
00:44:08
Vacations.
David Tungate
Director of Operations & Environmental Services
00:44:09
Yep.
00:44:10
Cover vacations and whatnot.
00:44:12
and then we have four management staff.
00:44:18
This is a really neat picture.
00:44:19
I found this in our adrenaline shots.
00:44:21
This is taken in February at Sugar Hollow just after a base storm.
00:44:25
So I'm just going to put that up if you're seeing all the triggers.
00:44:29
Are there any questions on the presentation today?
Ann Mallek
Member, Rivanna Water & Sewer Authority
00:44:32
You've used the term disinfection test.
00:44:35
Is that related to the GAC and if it's taking out the disinfection byproducts or is there any correlation to what I'm saying?
00:44:43
The term I remember from before the GAC.
David Tungate
Director of Operations & Environmental Services
00:44:46
The more disinfection byproducts we remove, the more total organic carbon that we remove from the water with the GAC, the less disinfection byproducts we'll have.
Ann Mallek
Member, Rivanna Water & Sewer Authority
00:44:56
Which is the end of the line probably.
00:44:58
Okay, thank you.
Bill Mawyer
Executive Director
00:44:59
We do disinfection testing in the distribution system for the chlorine to make sure there's enough to kill all the bad stuff that water out in the piping system.
SPEAKER_05
00:45:12
Okay, thanks David.
Mike Gaffney
Chair, Rivanna Water & Sewer Authority
00:45:15
All right, next item is long range utility concepts.
Bill Mawyer
Executive Director
00:45:19
Don't scare us though.
00:45:22
Well, I thought it'd be a good time to have just a little light conversation in addition to the fact there's one of my performance goals to talk about long range concepts.
00:45:33
So, therefore I keep changing the slide, yes.
00:45:37
So to start off, will we have enough drinking water in the future?
00:45:42
And I found a number of quips and quotes and Deborah found some nice graphics, but it shows you that 70% of the Earth's surface is covered with water.
00:45:56
And the oceans hold about 97% of that water.
00:46:00
Only 3% of the remaining water is fresh water.
00:46:04
Of the fresh water, 70% of the 3% is in ice caps and glaciers and the other 29% is in groundwater.
00:46:13
So there's only 1% of 3% that is easily accessible as fresh water in lakes and rivers, rivers at 1%.
00:46:24
So when we get our water from the Rivanna River, it's a very small proportion of the water that's available on earth.
00:46:32
Although clearly we can't drink
00:46:33
Saltwater, unless we do desalinization but ordinarily you cannot drink it, it will harm you, not help you.
00:46:42
The US has 4.3% of the world's population, yet we have 7% of the global renewable freshwater resources.
00:46:52
And I thought this was interesting about the, we have the largest freshwater lake system in the world.
00:46:57
Of course, the Great Lakes, which holds six quadrillion gallons of water, huge amount.
00:47:06
Colorado State University,
00:47:09
said that by 2071, a half of the freshwater basins in the country may not be able to meet the monthly water demand.
00:47:19
And from a worldwide perspective, the United Nations says 5 billion peoples or two thirds of the world's population will have a water shortage by 2050.
00:47:32
And they considered the impact of climate change.
00:47:38
So,
00:47:39
What should we think we'll hear about for the next 100 years and what considerations?
00:47:44
Emerging contaminants, regulations, technology, capacity, do we have enough?
00:47:51
Sustainability, portability.
00:47:54
Changes are always coming.
00:47:58
Emerging contaminants, we've talked about PFAS as an industrial product, the forever chemical,
00:48:04
that's gonna get more and more discussion and regulation.
00:48:08
Dioxane, which I was not hugely familiar with but that is in shampoo, shower gels, dish and laundry detergents and it can impact liver and kidney functions.
00:48:21
Perchlorate is associated with the defense and military operations, rocket propellant and fuels that they use
00:48:31
We've talked with you before about microplastics.
00:48:33
There's going to be a lot more discussion about those.
00:48:36
I think in different interrupters like pharmaceuticals and other personal care products as well as cyanotox.
00:48:47
We've shown you this slide actually before about PFAS, the forever chemical that's on cookware and it's a water repellent on clothing and stain resistance, re-proofing and friction reduction.
00:49:02
Next.
00:49:04
Microclassics again, that it could be thousands of these particles in your bottle of water.
00:49:10
And I'm sure the government EPA is going to have regulations on those.
00:49:15
Cyanotoxins that Andrea Bowles talks about a lot in our reservoirs, these blue-green algae that create odor and taste problems that Daniel and Dave have to deal with at our treatment plants to get them properly removed.
00:49:33
Technology, of course, is going to be a continuing change and influence on our industry from cybersecurity to artificial intelligence and what impact that's going to have and how we treat water and distribute it.
00:49:51
Capacity is an issue most everywhere.
00:49:53
Fortunately, or unfortunately, UVA is a very stable driver of our economy.
00:49:59
And we will see that we're going to have a growing population here.
00:50:03
for a long, long time, which combined with changing climate conditions that create drought and floods, that we may be the winner of coastal migration as water levels rise and low elevation areas, people start to move inland, they could want to stop in Charlottesville.
00:50:31
We showed this slide to you three years ago when we did our water demand calculations and supply study.
00:50:40
And in 2025, we estimate that the city will have about 50,000 residents and water users.
00:50:49
The service authority is gonna have about 72,000 water users in the urban area for a total of about 122,000
00:50:59
population that we're trying to provide water for.
00:51:03
But by 2070, those numbers increase at least for Rivanna about 40% that will be providing water for 170,000 people in the urban area.
00:51:16
So this does not count Rose or Scottsville or Redhill.
00:51:22
That's what we project.
00:51:23
And you know, we update this projection every 10 years.
Mike Gaffney
Chair, Rivanna Water & Sewer Authority
00:51:27
Sustainability is gonna be an ongoing baseline, please.
Bill Mawyer
Executive Director
00:51:31
Okay, let's go back.
00:51:33
The gray line at the top was that, that was a prior projection in 2011 by a different consultant, AECOM.
00:51:43
So we had just shown this at the time three years ago.
00:51:46
That was our projection in 2011.
David Tungate
Director of Operations & Environmental Services
00:51:51
Is this coming from Weldon Cooper?
Bill Mawyer
Executive Director
00:51:53
That we gather data from Weldon Cooper,
00:51:57
from the City Planning Department, the County Planning Department, and UVA, Office of the Architect.
00:52:04
So we compile these projections into how many people we're going to need to serve and therefore how much water we need to be able to provide.
Mike Gaffney
Chair, Rivanna Water & Sewer Authority
00:52:12
And Gail, this doesn't take any account from migration from the coast, right?
Bill Mawyer
Executive Director
00:52:18
Correct.
00:52:19
This is pretty much planning based data that in 2018 and 19 was put together.
00:52:27
So a number of years ago.
00:52:28
And again, we'll update this around 2028, 29 in order to have the 2030 report on what the population is, therefore how much water we will need and do we have it in our reservoirs
00:52:40
We measure the water in our reservoirs to see how much the impact of siltation has had.
00:52:47
So just because we had a billion gallons today, we may not have that in 10 years.
00:52:53
In fact, the prior study said we should anticipate losing about 15 million gallons a year in storage capacity.
00:53:00
So that's what we do.
00:53:01
Our bathymetric study, as we call it, through an airplane,
00:53:06
They can measure the amount of water in the reservoir.
00:53:10
Yeah.
00:53:10
Because it's reading the topography at the bottom of the reservoir and then calculating how much water is in there.
00:53:18
Probably an integration.
SPEAKER_05
00:53:20
Does that answer your question?
Bill Mawyer
Executive Director
00:53:24
Okay so you know you hear about these things energy management reduction and how we can use our wastewater biogas and we're talking with the city now about renewable natural gas whether we can contribute to the city's system solar facilities coming at the landfill and maybe on top of the addition here a carbon emission
00:53:48
Water reuse is very popular out west, you know we're blessed that we have a lot of water available so reuse has not been such a big program in Virginia, but in 100 years it may be.
00:54:01
Potable means you're drinking water.
00:54:03
Non-potable is non-drinking water.
00:54:05
So maybe for irrigation, we could have a water reuse system, but you have to have separate piping systems.
00:54:12
So it is an added expense.
00:54:14
Electric vehicles and equipment, you know, that's happening now.
00:54:18
And clearly it'll be more and more, I think of it in the future.
00:54:24
So some of the alternatives to the challenges ahead, we would say, at least I would say, that we may need more reservoirs.
00:54:33
We may look at a unified local systems where now we have a city utility service authority at Rivanna, in addition to the university being a customer of the city.
00:54:47
and even regionally we have localities like Green and Louisa who might be beneficial to have regional partnerships with.
SPEAKER_05
00:55:04
As an example,
Bill Mawyer
Executive Director
00:55:05
You know we've already planned and the board has approved that rather than spend 14 million dollars to renovate the North Rivanna water treatment plant which is not available when we have a drought because the North Rivanna River goes dry that we would decommission that but and we have a plan to connect the Rivanna
00:55:25
Reservoir to the Ragged Mountain Reservoir to improve our unification of our system.
00:55:33
But I have what I call a big box theory that the big boxes tend to work better in utilities.
00:55:40
And when we look at Moores Creek as a wastewater big box, we also have this little plant at Storm Robinson and
00:55:48
Smaller Plant at Glenmore.
00:55:51
For the future, we can see an opportunity that we would replace and eliminate these two wastewater treatment plants and probably make Glenmore a pump station and pipe all the wastewater back to Moores Creek.
00:56:05
And I mentioned over here, there are odor issues in Glenmore.
00:56:09
We got a letter from their community association yesterday.
00:56:12
wanted to talk to us about odors and noise and lights created by our wastewater treatment plant in Glenmore.
00:56:22
So that's a coming issue.
00:56:25
Similarly, we have large water treatment plants that they just told you about at South Rivanna Observatory.
00:56:34
But we have smaller plant in Red Hill and Scottsville.
00:56:38
Scottsville serves 700 or so people.
00:56:41
Would there be opportunities to unify those systems and to improve affordability so that the cost dollars per gallon could be reduced?
00:56:53
Because regulations are going to cause increased prices and we need to look for ways to mitigate those as much as we can, along with the regional partnerships.
00:57:04
We have a natural opportunity going north with green and orange, going east with Louisa,
00:57:12
you know maybe to the south even with Nelson.
00:57:17
Okay so when we really think further out 2070 and beyond I think the board has had discussion and very smart discussion that we should retain the Buck Mountain Reservoir as we have the coastal migration possibility we would have a good location to build another reservoir.
00:57:38
So that's what I would recommend that Rivanna would hang onto that property because one day there might be a reservoir there.
00:57:46
The observatory water treatment plant that we renegotiated that lease recently as a 50 year term that expires in 2069.
00:57:55
And that does have a 50 year renewal option at that time.
00:58:00
And that would be a critical point with the Rivanna and the university.
00:58:05
of whether renewal happens.
00:58:06
Otherwise we could be looking for another location for a water treatment plant.
00:58:13
The expansion of our two large water treatment plants within 50 years, that's gonna come back to the forefront to expand South Rivanna and observatory.
00:58:22
At a CROSA, we think Beaver Creek Reservoir has adequate waters for 50 years supply.
00:58:29
But again, that takes us right around that 2070
00:58:33
a time frame and there would need to be a plan of how to serve the growth in pros-e area.
SPEAKER_05
00:58:43
Yes, sir.
Mike Gaffney
Chair, Rivanna Water & Sewer Authority
00:58:44
Is that a picture of you on the moon there?
SPEAKER_05
00:58:46
Yeah, some days I feel like it.
Bill Mawyer
Executive Director
00:58:50
Thank you.
00:58:52
So again, we're blessed with a stable economy here driven largely by the university and its health system as well as the education and reservoirs are going to probably be the solution that we have to achieve a greater supply of drinking water.
00:59:08
We're not hooked to a river.
00:59:09
like City Richmond and Rigo are and they just catch what's going by.
00:59:14
We have to catch it and save it in our reservoir to deal with especially the changing climate and the protracted droughts that may occur.
00:59:24
So when it rains a lot, as the philosophy says, we won't be able to capture it and put it in our reservoirs to get us through the dry times.
00:59:33
Regulations are going to continue to emerge for the contaminants that we know about and those that we don't know about.
00:59:43
I see that local and regional unification of some of our systems may be opportunities to minimize our expenses and help the affordability of our products.
00:59:54
And as we have seen with the current strategic plan that we have and had for the last five years, it provides
01:00:01
The tremendous benefit that clearly the authority needs to maintain a long-term strategic plan to guide us through the changes that are going to occur over the next 50 to 100 years.
SPEAKER_05
01:00:16
So that's my story.
01:00:19
Any questions?
01:00:21
All right, thank you so much.
Mike Gaffney
Chair, Rivanna Water & Sewer Authority
01:00:27
Are there other items from board or staff not on the agenda?
Ann Mallek
Member, Rivanna Water & Sewer Authority
01:00:32
One little type that I didn't say before.
01:00:34
When Dave was talking about the MPA testing of the tanker, the original environmental impact statement for the second or third edition of the CROSA, the Western White House, it did not say if a tanker goes off that bridge, which was right on the shore, but when in all caps, which was a real clinker for me to make sure that was not going
01:01:02
So while people may have thought that was an outlandish thing today, it was considered 30 years ago as a reality.
01:01:09
So I'm just really grateful that you're doing that tabletop stuff because I think it's incredibly important.
01:01:15
And I was confused about or wondered how one manages regionalization when
01:01:22
Louisa gets her water out of the James.
01:01:26
Supposedly building, tunneling, whatever.
01:01:28
I mean, that's been 20 years as wells and stuff.
01:01:32
So that'll be, you know, that's their problem because that's Lynchburg water coming down there.
01:01:38
So I just, I'm glad that we have what we have and we need to protect what we have and figure out how many people we're going to have.
01:01:47
That is the problem.
01:01:49
Thank you.
Mike Gaffney
Chair, Rivanna Water & Sewer Authority
01:01:50
And Bill, I have a resolution here and I'm not sure where it was from.
01:01:56
for the adoption of the Regional and Natural Hazard Mitigation Plan.
01:02:00
That was on the consent agenda, and it was approved.
01:02:03
So we don't need to read this.
Bill Mawyer
Executive Director
01:02:05
Unless you'd like to, Mr. Chairman.
01:02:07
No, I'm good.
01:02:09
So the background on that is, as we apply for these federal grants, in which you've got several applications, they want to see that you're part of the Regional Natural Hazard Mitigation Plan.
01:02:19
And so the Thomas Jefferson Planning District Commission does that for all of the local city and counties.
01:02:25
and we're a party to that and so but we have they want uh FEMA wants us to officially adopt it so we're a partner to the plane so that's what that did okay is there any reason for a closed meeting no sir all right do we have a motion a second to adjourn second all in favor all right we are adjourned thank you so much thank you
