Leed / Water Treatment
Clean water for every community we serve.
Since 2009, Leed Construction has built and rehabilitated the treatment plants, reservoirs, and storage tanks that deliver safe drinking water to hundreds of thousands of New England residents — performing the most demanding process work inside live, regulated facilities, without ever taking a community off-line.
Infrastructure that can't go offline.
A water utility doesn't get to pause. Every project we take on has to be planned around an unbreakable constraint: residents must keep receiving clean, pressurized water — every hour of every day — while we rebuild the system that delivers it.
A trusted partner to New England's water authorities.
Leed is a go-to contractor for the South Central Connecticut Regional Water Authority and for municipal water departments across the region. We've rehabilitated filtration trains, re-roofed finished-water reservoirs, replaced storage tanks, upgraded chemical feed systems, and rebuilt structural elements — frequently with the parallel process line kept in continuous service beside us.
That work demands a contractor who understands NSF-61 materials, EPA disposal standards, confined-space and dewatering protocols, and the regulatory expectations of public health agencies — and who can sequence it all without a single interruption to municipal supply.
02 — Capabilities
Full-scope treatment work.
From the intake to the distribution main, Leed self-performs the disciplines that keep a treatment plant running and pushes the rest through a vetted bench of specialty subcontractors — all under a single accountable team.
Process & Filtration
Filter rehabilitation and dual-media replacement, underdrain rebuilds, automatic backwash systems, aeration and process pumping, and clearwell work — executed to EPA and NSF-61 standards with full media disposal documentation.
Storage & Containment
Finished-water storage tanks, geodesic aluminum domes, reservoir roof reconstruction, structural concrete repair, and secondary containment — built and renovated while parallel storage stays in service.
Chemical Feed & Mechanical
Chemical feed system upgrades, metering and dosing, valve and weir-gate replacement, fall-protection systems, and the process piping and controls that tie new equipment into legacy plants.
Building around a live system.
The hardest part of water work is never the construction — it's keeping the water flowing while you do it. That's our specialty.
Zero interruption to municipal service.
On project after project we've isolated and dewatered one half of a treatment train, installed hydraulic separation curtains, and lowered heavy equipment dozens of feet below grade — all while the parallel basin kept supplying the community without a drop of lost service or a single boil-water notice.
We plan every shutdown, bypass, and tie-in during preconstruction, coordinate closely with plant operators, and sequence the work so the utility never has to choose between a needed repair and uninterrupted supply. When the project is done, the system is stronger — and residents never noticed a thing.

Planning a treatment, storage, or process upgrade?
Bring us in early. Our preconstruction team helps water authorities and municipalities phase complex upgrades around an uninterrupted supply — and prices the risk out before the first shutdown is ever scheduled.
