SCDPW Bergen Point Wastewater Treatment Plant Grit Facility Improvements
D&B was retained to provide engineering and architectural design services for the upgrade and expansion of the Bergen Point Wastewater Treatment Plant’s grit removal facility. The system was designed for 40.5 MGD ADF and a peak storm flow of 100 MGD. The grit system was expanded to reliably remove grit at peak design flows and includes an additional grit tank. The high maintenance chain and flight system will be replaced with an air mixing technology that will separate grit and lift it above the tank water surface for disposal.
The principal features of the work includes the construction of a concrete grit channel; installation of 12 grit airlift systems: construction of a new grit washer building complete with lighting, HVAC and architectural features; demolition of existing mechanical and electrical grit systems; demolition of HVAC system in the existing grit building and construction of new HVAC systems, mezzanine levels and electrical control and blower rooms. The work also includes the relocation of various underground utility systems and installation of new utilities, as well as miscellaneous site work, dewatering, erosion control, and system startup and testing.
