Tata & Howard provided design services for a new Dissolved Air Flotation (DAF) facility with a design capacity of 8.0 million gallons per day (mgd) for the Long Pond surface water supply for the Town of Falmouth, MA. In addition, Tata & Howard is providing water treatment plant construction administration. The water treatment plant (WTP) will utilize coagulation, mixing, flocculation, dissolved air flotation (DAF), dual media filtration including granular activated carbon (GAC) above sand, chemical feed systems, and an intermediate ozone feed. Building components include HVAC, plumbing, fire sprinkler, gas and electrical services. Other work includes site work with exterior piping systems, exterior above and below ground tanks, sludge holding lagoons, construction of a garage, new raw water intake and pump station, directional drilling of raw water mains, and demolition of equipment and site piping at the existing water treatment facility.

The construction of the Long Pond Water Treatment Plant progressed on schedule through the winter months of 2017.  The finish work was completed at the new raw water pump station, and the pumps have been activated to draw water from Long Pond and pump it over to the new water treatment plant. After the the installation of windows and doors, the new water treatment plant is fully enclosed and internal finish work was completed.  Startup and testing of the equipment and treatment processes at the new water treatment plant are underwaydji_0051.  Following startup and testing, the water treatment plant will be activated and ready to provide water to the Town of Falmouth.

The work was funded under the SRF program. The project is on schedule and expected to be completed in first half of 2017.
