DBO Wastewater Treatment Plant

Private Development Wastewater Treatment Plant

The A.D. Makepeace Company selected Weston & Sampson to provide a wide range of water and wastewater engineering and owner’s project management services for a large private development in southeastern Massachusetts. This mixed-use, residential development concentrates its footprint through the use of innovative local bylaws and modern conservation concepts to maximize open space and protect local resources within the project area.

Services for this project have included developing a wastewater system, including collection, treatment, and groundwater discharge for the proposed development, along with an assessment of impacts to the adjacent resource areas. Our work included providing extensive assistance with local special permit approvals, Massachusetts Environmental Policy Act (MEPA) process review (Expanded Environmental Notification Form and Final Environmental Impact Report), and the Massachusetts Department of Environmental Protection (DEP) Groundwater Discharge Permit. We also developed a siting and process selection analysis for the Wastewater Treatment Facility (WWTF) and effluent disposal fields to serve the proposed development. The wastewater facility and disposal systems will ultimately be capable of treating approximately 400,000 gallons per day.

Following that, Weston & Sampson was charged with assembling a team to construct and eventually operate the WWTF under a Design-Build-Operate contract. We assumed the role of Construction Manager at Risk, coordinated the construction effort, and acted as Owner’s Project Manager. Our affiliate firm will operate the collection system for the first five years.

Weston & Sampson also provided permitting and engineering services for the development, treatment, storage, and distribution design of the drinking water system for the development. Our services included source (Water Management Act) permitting and approval. Weston & Sampson designed the well development, treatment facility, storage tank, and distribution system. We also provided project management services for a water treatment, storage, and distribution system. We managed the overall construction as the Owners Project Manager in concert with the ongoing wastewater treatment and collection system construction. Our affiliate will operate the water distribution system for the first five years.
