  • EP’s Role


The Tri-Town Board of Water Commissioners (Tri-Town) represents the towns of Braintree, Randolph and Holbrook. Tri-Town was created through legislation in the late 1880’s to manage the jointly utilized water supply known as Great Pond bordering the towns of Randolph and Braintree. The Great Pond Reservoir System consists of the Upper Great Pond Reservoir, the lower Great Pond Reservoir, and the Richardi Reservoir.

The Great Pond Reservoir System is the source of 100 percent of the drinking water for these three communities. Tri-Town maintains the reservoir dam system and provides overall management of the water supply system. Braintree and the Joint Randolph/Holbrook Water Board own and operate individual WTPs on the Lower Reservoir portion of Great Pond.

The Braintree Water Treatment Plant and the Randolph/Holbrook Water Treatment Plant (WTP) are nearing the end of their useful life. The Town of Braintree and the Joint Water Board (Randolph/Holbrook) have completed a number of upgrades at each WTP over the years, however, it has come to a point in time where a new facility is required to replace each of the treatment plants. Rather than construct two separate plants the communities determined the most cost effective approach was to construct one Tri-Town Regional WTP (TTRWTP) on available land adjacent to the town of Braintree’s WTP. After many years of planning and preparing for the construction of the TTRWTP, the Tri-Town Water Commissioners (Tri-Town) have contracted Environmental Partners (EP) as their Owner’s Project Manager (OPM)

As the Owner’s Project Manager, EP represents Tri-Town for the project. Services provided include project oversight and all services associated with project management of a publicly constructed water treatment facility. This multi-million dollar project includes a new 12.5 MGD dissolved air filtration regional water treatment plant and redundant sub-aqueous transmission mains.

The first phase contracted encompasses a review of the Pilot Plant Study conducted in 2004 to obtain approval from MassDEP on the approach for treatment, reviewing 25% design plans, conducting constructability and value engineering workshop, preparing a new preliminary conceptual design layout, and creating a detailed probable cost estimate and schedule for the overall project. Subsequent phases will include conducting Designer Selection Process for the Tri-Town Board, oversight of Designer services and deliverables, oversight during construction, startup, and warranty periods. In addition, Environmental Partners will work with the Board on creation of organizational structure for the new regional facility and support on funding opportunities.
