Project Description

camdenmuaD&B/Guarino designed a new 7.3 million gallons per day (mgd) pump station and a 7.7 mile 30 inch ductile iron force main to convey wastewater from the Atlantic Basin portion of Camden County to the Camden County Municipal Utilities Authority (CCMUA)Wastewater Treatment Plant. The CCMUA plant is an 80 mgd Pure Oxygen Activated Sludge facility discharging into the Delaware River.

The Cross Keys Road Pump Station’s average daily design flow is 7.3 mgd with a peak design flow of 17.7 mgd. The Pump Station includes three 305 hp submersible pumps (two operating, one standby), one manual bar screen and two grinders. Backup power is provided by a diesel generator.

The design services included site investigation and data collection, review of aerial photographs to develop alternative force main routes and sites for the pump station, and a topographic survey to develop a base plan for the pump station site and force main route identifying all utilities, aboveground features and paving features. Utilizing all field work, D&B/Guarino developed a Technical Design Report that established design criteria for the pump station, force main, construction materials, road restoration, preliminary plans, construction cost estimate, construction schedule and needed permits.

Slide 1D&B/Guarino prepared all permit applications including calculations, plans and supporting documents to the Camden County Highway Department, Camden County Soil Conservation Service, the New Jersey Department of Environmental Protection and the New Jersey Pinelands Commission.

D&B/Guarino developed contract documents (plans and specifications) for bidding. During the bid phase, services provided included assistance in advertising; attending pre-bid meetings; updating the engineer’s construction cost estimate; reviewing bid results and recommending contract award.

During the construction phase, D&B/Guarino will provide the following design services: review shop drawings; response to contractor clarification requests regarding design; inspection service as needed for design intent; attend monthly progress meetings; provide the CCMUA with the Project Record Documents based as-built plans; and provide a one year project certifications required by the NJDEP permit.
