Todd, speaking for wastewater operations, said the interceptor upgrade survey and wetlands delineation are scheduled for early spring 2025, 90 percent bid documents are expected in fall 2025 and bidding of the interceptor may occur in early 2026 with construction and completion likely by 2027. The interceptor project will replace the final segment from Mayflower Avenue to William Street and will require easement and wetlands work; staff said the work should not affect the public heavily because most of it runs through woods and easements.

On sewer rehabilitation and inflow/infiltration (I&I) work, Todd said 60 percent plans are due in February 2025 and the town plans to bid the I&I rehabilitation in April 2025 for midsummer–late‑fall construction. The I&I program will include pipe lining, manhole rehabilitation and targeted efforts to identify and remove illegal sump pump and stormwater connections to the sewer system. Todd said the town has studied I&I for years but is now moving to construction; staff estimated a potential flow reduction in the 20–25 percent range as an optimistic target but noted results will depend on scope and contractor performance.

Plant-side work: Todd said tertiary-disc-filter equipment is on order and the town expects installation in mid‑2025; the equipment purchase was described as roughly a $400,000 project and will increase peak handling capacity (one disc filter online would allow higher permitted peak flows). Staff also reported the contractor for the bypass and slide gates project will submit 90 percent documents in March 2025 and bidding is planned in April–May 2025 for construction during low-flow months (August–December).

Standby power: wastewater staff reported completion of permanent standby generators at several pump stations for the first time in department history. The rotary pump station generator is installed and ocean‑area generator work is at final‑installation stage; staff said both generator projects should be complete in mid‑February.

Next steps: staff will finalize 60–90 percent design documents for I&I and the interceptor, bid the I&I work in April 2025 and start construction in summer 2025. The interceptor work includes a longer lead time for surveying, permitting and wetlands work and is expected to reach construction in 2026 with final completion by 2027.","mediaType","Video","parentTitle","Middleborough Select Board/Water & Sewer Commissioners 1-29-25","oneSentenceSummary","Wastewater staff told commissioners on Jan. 29 that the interceptor upgrade survey will start in early spring 2025, I&I (inflow and infiltration) rehabilitation will be bid in April 2025 for construction in summer/fall 2025, tertiary-filter equipment is on order and pump-station standby generators are nearing completion.","taxTitle","Town of Middleborough, Plymouth County, Massachusetts","taxId",54300,"location","headline","","shortSummary",{"_33":76,"_35":36,"_37":38,"_39":77,"_41":78,"_43":79,"_45":80,"_47":81,"_49":82,"_51":83,"_53":84,"_55":56,"_57":58,"_59":85,"_61":62,"_63":64,"_65":86,"_67":68,"_69":70,"_71":68,"_72":73,"_74":73},6363325,"Middleborough outlines South Wells consolidation, pilot work and SRF application plans",828,1358000,2186000,"/Search/View?dp=1&key=2166343-c86e645ad2400ca552ae880fca98db4c&start=1358&end=2186","https://assets.pipeline.soar.com/2166343-c86e645ad2400ca552ae880fca98db4c/thumbnail_1358000.jpg","/articles/6363325/Town-of-Middleborough/Plymouth-County/Massachusetts/Middleborough-outlines-South-Wells-consolidation-pilot-work-and-SRF-application-plans","https://secure.pipeline.soar.com/6363325-6b956d504e707153b38ebe1749df2fe2/orig.mp4?Expires=1771183948&Signature=ZRu~2KHg8CWvXYIH-yvDkbgeOYMULXDqNsRqj7e0-XzH8GraMY1PZILKtl368sh-6QFCtXkPYoZr4OsOSgGzQBUeFHc8y6HzRV7I4yb6CKRn8Ul3N7EaiWZ7qgpwLtDx4f4R498GZHt8JOOp3UcbjTZAafymdnm8cm3uh9SAWuZ5CPhZ1naq~ZwUUKe2cgy6kRf4OcUr1HBOG3~JjyafcPzknfbYEuDdZHi1l5Zzspaloska~dTCao9ugiHMOi0gZp3ckl3hI~zhRQqXj-dhwz-L0VTv-lnd~VlTkdA6KzX7QAxgV7kbjothxRjUdoaOI~uOyXTy7ZIAGoU4fLgmGg__&Key-Pair-Id=KUT5TJCACFTXG","MIDDLEBOROUGH, Mass. — At the Jan. 29 Water and Sewer Commissioners meeting staff described plans to combine five south-side wells into a single South Wells water-treatment plant, to continue pilot testing, and to seek SRF (State Revolving Fund) funding starting with an SRF application planned for August 2025.

Leah, the project engineer, summarized the engineering rationale: combining a set of wells with varying iron, manganese and PFAS profiles requires a centralized filtration plant rather than treating each source separately. “When we lump it together, you have a 2,500,000 gallon per day plant, which is not a small plant,” Leah said.

Town staff described the proposed footprint and operational approach: they plan to use biological filtration for iron and manganese to match other town plants and granular activated carbon (GAC) or alternate media for PFAS removal. The draft facility footprint is roughly 9,000–10,000 square feet for a minimalist design; staff said they prefer the Miller site (about 18 acres) for the consolidated plant because it has sufficient upland area and fewer permitting constraints than other well sites.

Staff said pilot testing is ongoing and has encountered operational issues — the purpose of piloting is to discover treatment complications at a relatively small cost before committing to a multi‑million‑dollar plant. That pilot work is typical for a project of this scale, staff said, and is intended to inform the feasibility and final design.

On cost and schedule, staff reported a planning range: a combined Mazares (spelled variously in the meeting) and South Middleborough minimum project budget of about $35 million up to a maximum of $45 million; staff cautioned the range reflects alternatives and is a planning estimate. The project team recommended applying for SRF funding in August 2025; an SRF application on that timeline would place design and bidding on a multi‑year schedule, with construction likely in the 2027 timeframe under a typical SRF schedule.

Staff also warned about hydraulic impacts to the distribution system. Combining dispersed sources into a single high‑capacity pump location will increase flow and pressure demands in the distribution network, and the team is reactivating a hydraulic model to identify potential transmission and distribution upgrades — including possible new mains — needed to integrate the plant without causing pressure or water‑quality impacts.

Next steps: staff will complete pilot results and feasibility reporting, present a design-article recommendation to Town Meeting this spring (separate articles for East Grove and the South/Mazares work were discussed), and prepare an SRF application in August 2025 if the Board approves that schedule. Staff emphasized pilot findings will determine final treatment media and may affect whether smaller, lower-cost PFAS technologies can be used at specific well sites.","Commissioners were briefed on a proposed South Wells 2.5-million-gallon-per-day plant to consolidate five south-Middleborough wells, pilot testing challenges, and plans to apply for SRF funding in August 2025; town staff gave a $35–45 million range for combined Mazares/South Middleborough project costs.",{"_33":88,"_35":36,"_37":38,"_39":89,"_41":90,"_43":91,"_45":92,"_47":93,"_49":94,"_51":95,"_53":96,"_55":56,"_57":58,"_59":97,"_61":62,"_63":64,"_65":98,"_67":68,"_69":70,"_71":68,"_72":73,"_74":73},6363329,"Middleborough says East Grove treatment-plant design is complete; bids due in April",2490,708000,3198000,"/Search/View?dp=1&key=2166343-c86e645ad2400ca552ae880fca98db4c&start=708&end=3198","https://assets.pipeline.soar.com/2166343-c86e645ad2400ca552ae880fca98db4c/thumbnail_708000.jpg","/articles/6363329/Town-of-Middleborough/Plymouth-County/Massachusetts/Middleborough-says-East-Grove-treatment-plant-design-is-complete-bids-due-in-April","https://secure.pipeline.soar.com/6363329-01ccc96abff6429eb6e2e53ea4e7cb11/orig.mp4?Expires=1771183948&Signature=ERPzVCb2oIBgfEGlk~945Ul00p1O2p5bmzZUSH39D2uTmix6KGoRYNfuaLY0RHfldvbC2oAwa5EuB7GFaNGd41XPwvH6T75pBnFBaM4OWfUSHokYxDeXlRiMiuOme4Lf6o3BYv0GmH3TtNcBUCZbe49F8VLgU8giCkQykdQ3PnPP-8II~yo6f1jpER8JHSrP4jdIj6at9sT-BnZR3StgCU9OBOynfn6Er4SBD9Qv97klApniXoaabRjnT4QAjKrdaPmhDh5jNUSqwEod0R3tEipj5GDzjB9bn8OKvD9JvPp1zXefo36zA8lYylrljRYKdGHiuNgu8~jr-aTnBvVf6Q__&Key-Pair-Id=KUT5TJCACFTXG","MIDDLEBOROUGH, Mass. — The Water and Sewer Commissioners heard an update Jan. 29 that the East Grove Water Treatment Plant design is complete, prequalification of subcontractors is underway and bid openings are scheduled for early April, with contract execution planned before the end of the town fiscal year.

The update matters because the plant will replace aging iron-and-manganese filters, add granular activated carbon to remove PFAS, and is large enough that construction timing and funding decisions will come to town meeting. Brian (chair of the Water and Sewer Commissioners) told the board the 90 percent design estimate remains within budget but that the town will post a placeholder warrant article so Town Meeting can address any shortfall after formal bids arrive.

Leah, the project engineer for the East Grove Treatment Plant with Weston & Sampson, told the board the design is finished and staff are beginning the contractor prequalification and bidding sequence. “The design for the East Grove plant is complete. … That bid opening is April 2nd, and then the GC bid opening is April 23rd,” Leah said. The prequalification process includes multiple filed-sub categories; the team reported about 67 filed-sub bidders overall and about 10 general contractors had requested prequalification materials.

Town staff said the plant will include biological treatment for iron and manganese — the same approach used at East Main — with granular activated carbon on the back end for PFAS removal. The project team emphasized the storage/garage element will be included in the East Grove contract to preserve access to State Revolving Fund (SRF) principal forgiveness; the town expects at least 11 percent in principal forgiveness tied to SRF requirements and staff said excluding the garage now could forfeit that benefit.

Schedule and procurement details provided to the commissioners: prequalification and filed-sub processes are underway with a February deadline for prequalification; filed-sub bid documents will be published and opened the week of April 2, followed by general-contractor bids on April 23. Contract execution is expected before the end of the fiscal year in June; staff estimated construction mobilization 6–8 weeks after contract award and an 18– to 24-month construction window, with plant startup likely in late 2026 and official completion into 2027.

Staff also described the prequalification rules used for SRF-funded projects — including WBE/MBE goals of roughly 23–24 percent that SRF requires — and the requirement that bidders carry A-rated bonding. Leah said the garage as part of the East Grove site provides economy of scale and allows smaller, more minimal upgrades at other plants.

Next steps: staff will complete the prequalification vetting, open filed-sub and GC bids in April, and present final bid results and a placeholder warrant article to the Select Board/Town Meeting if the low bids indicate a need for additional appropriations. Town staff asked commissioners to be available near the end of June for contract execution if bids require action before the July fiscal date.

Charges, specific bid prices and any final contract awards were not reported at the meeting; staff said those numbers will be available once formal bids are opened and evaluated.","Town staff told the Water and Sewer Commissioners on Jan. 29 that East Grove Treatment Plant design is complete, prequalification for filed sub-bidders is underway, bid openings are scheduled for April and the project will seek SRF principal forgiveness that hinges on including a maintenance/storage garage.","actionData","errors"]
