WWCo and `Sconset Water Companies (SWCo) Discussion New Well Willett — Referred to a graph reflecting the growth trend with proposed developments; will have to be able to pump 1.85M gallons -per -day (GPD); The Department of Environmental Projection (DEP) projected pump number for 2021 is 1.9 MGP. We have to assume the developments will all get built out. Eventually we'll get to where we can't go over the 3.1. At that point we will face outdoor water restrictions; that will have an economic impact on the Island. Hussey — Presumably the people moving into the developments are Island residents, he doesn't understand why there would be an increase in water usage. Willett — The State understand families are living in secondary dwellings and will move into the developments making those apartments available; they look at max capacity. It is crucial to start looking for a new source for water, which could take up to five years. Reviewed areas WWCo is looking at for the new source well. Welch — Asked for clarification on the land swap with Nantucket Islands Land Bank and if it is part of the land credit. Willett — The land credit would help with mitigation, allowing an increase in the pumping limit as well as being a new source of water; it would add over a million gallons per day. Lowell — Asked if the State allows for Nantucket to have an average per day. What we pump in winter is far less than in the summer. Page 1 of 5 CapProCom Minutes for October 04, 2018, adopted Oct 18 Willett — The State is using the 2010 census data, which we know is way off. He provided information that would allow the State to recalculate usage. The State hasn't assessed the Cape and Islands; we did our own assessment and proved it was unbiased. Welch — Asked for a general water -under -the -ground scenario. Willett — We have three levels of aquifers: upper level feeds residential wells; middle level is 14,000 -year-old glacial water from which WWCo wells draw; lower level is a glacial lake older than the middle level and has no pumps. The lower level would be a mining charge; water taken won't be replaced. Through our budget, we pay annually for a geo-physicist team from USGS to review the layers across the island. They did find saltwater intrusion in Madaket We might learn that the glacial lake deposit ends and doesn't extend into Madaket; that would allow for the saltwater to come up. Welch — Asked if the low topography of Madaket and proliferation of wells plays into the intrusion or that the water tapers off there. Wille# — It's a combination of both; if they find the glacial lake continues into Madaket, the density and number of wells in Madaket; we now water Madaket Welch — Asked if there is a threat of saltwater weepage into the overall source of water is not provid d to Madaket. Wille — Most of Madaket wells use the upper aquifer. The study work will be added to the website; just got an update on the 60 -year pumping log that shows no saltwater intrusion and slight connectivity at the lower level of the upper aquifer. Lower. — Asked if we know how many gallons are pumped to Madaket; we added growth. Willett — Our plan is to add zone meters. Due to the seasonality of Madaket and Cisco, the goal is for 4 master meter on Madaket Road before Fisher's landing and one going out to Cisco; it would help with the permitting process. Welch'— Asked the size of the pipes to Madaket. Willett — 10 and 12. The master meter would be just like the house meters that can be read with the click of a button. It sounds expensive, but the information is priceless; it would help with the permitting process. Welch — with respect to the master meters; asked if the locations would be part of the negotiations or something that would be revisited with the State. Willett — It would be a revisit. He brought a hard copy of the report put together for the renewal permit; he will email it out to the committee. Welch — He would like a hardcopy of the report. Kickham — Asked if any DEP numbers include private systems. Willett — just the public water supply. The merger has been approved; WWCo will take over SWCo. Overtime, that would lead to one water rate across the Island. Lowell, — This is a reset for Nantucket with the State. Talking about the new growth sounds scary when you hear it; as far as how the State looks at us, Madaket, Cisco, and `Sconset weren't included in the numbers. Willett — The State doesn't get the seasonality of the Island. We've invited them repeatedly to see what we're dealing with in the winter and again in the summer. Madaket behaves differently than the Town of Nantucket so could be considered an independent entity. Lowell — The land for the new well and pump, asked if we will need another tower. Willett — We won't need another tower; we fill up the existing towers over night He's working with National Grid to come up with off -hour pumping hours: after the last shower before irrigation comes on. There are existing areas that are looking to be hooked up to Town water. Kickham — Asked what the next three-year cost estimates are to complete the project Willett — $1.5M will get us close to finalizing the well going into the middle aquifer; the pump station would be separate. He would like the two wells in the upper aquifer to become back-up wells for emergency only so WWCo doesn't have to pump from the upper aquifer. About four Page 2 of 5 CapProCom Minutes for October 04, 2018, adopted Oct. 18 years ago, the `Sconset pump station cost just under $1M; the cost for this will be higher depending on the economy; it doesn't need to be a big building. Welch — Asked about the background experience with the vendor doing the study. Willett — He's been working with us for years and coming to Nantucket his whole life. He does a lot of work with Haley and Ward; the specialize in ground water. Welch — Asked what the maximum daily volume was and how frequent. Willett — The max-day was in early August at 4.3M GPD. We went over 4M GPD under ten times. With our existing equipment, we could pump close to 5M GPD. Welch — We are going to be looking at substantially more pull on the source once all the developments come on line. This new source would allow us to meet the demand. Kaizer — Asked if there is a state-mandated daily maximum that cannot be exceeded. Willett — It's close to 5M GPD. Each well is given a maximum pull; in the summer each is pulling 1.1M GPD. Welch — Asked for clarification on the Tap. Willett - 150 to 180 Welch — Asked how receptive DEP is to the new data. Willett — DEP is reviewing that data now; they've accepted it. Welch — Asked about the credit for land held in conservation and how it affects the maximum daily allowance. Willett — Explained how that is calculated; for each acre in conservation we have an additional 9,000 gallons. The Island has done well keeping land in open space; the whole island is a recharge for the aquifer. He hopes there will be additional credit. When the State finishes its review and give us 1.9M GPD for 2026, every five years we can go back with new data and challenge the 2026 number. Welch — He'd like the pump house flagged as an outstanding project and for it to carry a $1.8M estimate. `Sconset Water-main replacement Willet — We've agreed to work with sewer in all areas; `Sconset was tagged for sewer work and we will follow sewer with replacement of the water mains. The capital numbers will look bigger overall but it will actually be less: one engineer, one opening, one paving, etc. Welch — Asked how the two departments are carrying the cost. Willett — The engineers were asked for a cost breakdown per foot. Excavation and paving and other duplicated numbers are discounted at the end. Kickham — Asked if Water and Sewer per-foot costs are the same or different. Willett — Sewer is much higher per foot. Water usually ranges from $175 to $210 per foot. Sewer starts at $250. When we work together, the Sewer numbers will drop. Hussey — The Haley and Ward estimate for Prospect Street, asked what that number on the CIP form that ties back to. Willett —It's informational; it was our latest project. We've worked with Robert B Our and CC, who are both on Island and will be bidding for the water-main replacement. Hussey — For the new developments, asked where the money comes from for the infrastructure. Willett — The developer pays for and does the work. The Town would pay for Waite Drive; CC is laying the pipes for Richmond Development. Out Years Welch — We covered the pump house. With respect to the water-main, he'd like a list of FY2017 and FY2-018 actual water-main replacement versus proposed and include any FY2019 updates. Willett — Asked how money appropriated for one street can be used for another area. Welch — With respect to internal process, that street/area information is useful for planning. In respect with what goes to ATM, that information isn't necessary; FinCom just needs to know what it is for. Page 3 of 5 CapProCom Minutes for October 04, 2018, adopted Oct 18 Lowell — Asked how this can be juggled around smoothly. Welch — With Town Manager and Finance appropriating funds for a scope versus a location, the funds are available for that type of work. Turbitt — If Mr. Willett wants the water mains camera'd, we can add that In terms of working together, WWCo has internally ID'd streets they want to work on. We identify "water main" work. Sewer is eligible for SIS money, so its appropriations has to be written differently; we've managed to write it so there is some flexibility. Hussey — Asked about painting the water towers. Willett — The conditions have to be just right, no moisture. They try to match outside temperatures to the temperature inside the water tank to prevent having condensation. Welch — Asked about the rate study along the lines of the capital perspective and using retained earnings. Also he has questions about expansion and betterment Willett — We're about 75% done with the rate study; as soon as the information arrives, he will forward it to Mr. Turbitt. When the study is done, we will have a line in the budget called Reserve Fund. Recently we had an emergency in `Sconset; a reserve fund would have been very helpful. He will also make the geo-physical survey as part of the budget He hopes the rate study will be complete by the end of the month. Lowe — Asked if there needs to be a person making rounds at night checking the pump Wille — No, the system has an alarm. In the `Sconset emergency, the alarm failed. He's looking into a separate system for redundancy. Welch — WWCo is getting requests for expansion of water; asked if that is be paid for out of WWCo rate fee or if it is a capital expenditure on the private side. Wille — In Madaket, WWCo fronted the money and paid 75%; we then split the rest among the connected residents as the connector fee. Kickham — Asked about the Water Testing Laboratory. Willett — There is a private donor who wants to donate for the new laboratory. We have two spaces that could house the lab: one above the shop and another space. He thinks the lab could sustain itself. We would have a certified lab that could do certified private testing as well as Natural Resources, DPW/Landfill, and WWCo. Once we get better numbers on potential operating costs and money spent on shipping and testing, there will be support for this. He's not sure if it will be a capital expense or an inter -department project; have to look at who will run it Health Department is heading up the work. Discussion and Ranking Bridges — Asked if the $1.5M for the geo-physical survey will come out of the rates or debt exclusion. Welch — It will come out of water enterprise and will be a borrowing. Turbitt — It will come from rate payers. Bridges — Wonders why the study is such a high priority. Kickham — This was projected for 5-7 years out; it's moved up for planning purposes. Welch — Asked members to fill out the RORIs. • •J, IM 16 gig 11•' • 1. Li sora Reports a. Sewer: Welch —He'll meet with Sewer on Tuesday and they will present on Thursday 2. Committee Reports a.
