Water Resources: Wastewater Infrastructure - Example Projects

Sussex County MUA -Vernon Pump Station #3

​CP Engineers (CPE) prepared the design and construction documents for the construction of the Vernon Pump Station.  Included in this project was the installation of a coarse Mensch Crawler Screen, two (2) new 925 GPM variable speed submersible pumps, a 350 kW backup generator, an emergency overflow system, wet well, dry well, new concrete building, SCADA control, bypass pumping, flow meters and hydrogen peroxide injection system. CPE provided construction administration and observation services and was the liaison with the Contractor, Administration and Operators on this sensitive project.  The project was successfully completed on-time and on-budget.

NJ Division of Property Management & Construction - Island Beach State Park Sewer System

CP Engineers (CPE) provided the design of a vacuum sewer system to replace the existing septic systems at Island Beach State Park (IBSP). The drastic variation in seasonal flows combined with flat topography would be problematic for a traditional gravity system.  A vacuum sewer system was able to service the inconsistent, seasonal flows and avoid long detention times, septic conditions, and settling solids.  By pulling (vacuum) rather than pushing (pumping) the wastewater through the system, the system generally remains empty during the extended low flow periods.  CPE designed the vacuum system, including two (2) vacuum pumping stations, to service over seven (7) miles of parkland, and ultimately conveying the wastewater to the Berkley Township Municipal Utilities Authority. 

US Army Garrison West Point, NY – Upgrade to South Dock Pumping Station

​CP Engineers provided design and construction support services for the repairs of the Station.  The Station has been upgraded with 3 VFD dry pit submersible pumps, complete upgrade of the electrical system, submersible transducer and back up float for level control, influent grinder, magnetic flow meter, ventilation, lighting, masonry repairs, and the roof.  The station is very small for the flows for which it provides service, with a wet weather flow up to 2,400 gpm.  The location of the standby generator which was constructed over the stations force main, made the design and construction work on the relocated force main that much more difficult.  

Sussex County MUA – Upper Wallkill Interceptor Extension

​CP Engineers provided planning, design, permitting, and construction phase services for the project which connected the Township of Sparta to the Upper Wallkill System.  The project included gravity sewers, two major pumping stations, five miles of force main, and a corrosion control facility.  Project challenges included a significant environmental permitting effort, hilly terrain with significant rock, and mitigation of potential corrosion issues due to the extended length of force main.

Warren County (Pequest River) MUA -Warren Haven Pump Stations Nos. 1 & 2        Upgrades

CP Engineers provided design, permitting, bid and construction phase services for the upgrade of two major pumping stations within the Authority’s Oxford Interceptor System.  The project scope included: increasing the wet well volume; upsizing of the pumping units; replacement of piping, valves and flow meters; and the upgrade of electrical systems, controls systems and the emergency power systems.  A major project challenge involved extended bypassing of the stations during construction.
