Also due October 14 at 2 p.m. in Hampton Bays: a contract to install the carbon filter equipment for a new PFAS treatment system at the water district's Plant No. 3.
This is the GAC absorber contract — GAC stands for granular activated carbon, the filter media that pulls PFAS chemicals out of the water. It's bid separately from the Contract F foundation work for the same plant, and it's a water/sewer trade scope rather than straight general construction. Like the foundation contract, it requires a bond and shows no site walk-through listed in the posting. The question deadline already closed on October 7.
The treatment system calls for four pressure filters loaded with that carbon media, housed inside a building so it can run year-round — not an outdoor skid. The district is also doing electrical and control upgrades, plus work on existing wells and buildings, as part of the same overall project.
The money behind this is a $4,705,200 state grant the district landed in 2024, and the reason for the rush is regulatory: the allowable PFAS level in drinking water is set to drop from 10 parts per trillion to 4 parts per trillion by 2027, so the district needs this treatment running before that deadline tightens. For a water/sewer contractor who handles filter vessel installation, that federal clock is the thing driving the schedule here, not just local preference.
Documents are on the Town of Southampton's ProcureWare portal. Bids are due 2 p.m. on October 14 — the same hour as the foundation contract for this same plant, so check both if your shop does either scope.
