Our firm 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 new 925 GPM variable speed submersible pumps, a 350 kW backup generator, an emergency overflow system, wet and dry wells, new concrete building, SCADA control, bypass pumping, flow meters and hydrogen peroxide injection system. We provided construction administration and observation services and acted as the liaison with the contractor, administration and operators on this sensitive project. The project was successfully completed on-time and on-budget.
Our firm provided the design of a vacuum sewer system to replace the existing septic systems at Island Beach State Park. 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. We designed the vacuum system, including two vacuum pumping stations, provided service over seven miles of parkland, and conveyed the wastewater to the Berkeley Township Municipal Utilities Authority.
Our firm provided design and construction services in support of the design/build team for the construction of the upgrade to the South Dock Pumping Station. The station is physically undersized relative to the amount of flow it conveys, requiring creative methods for equipment selection and layout. In addition, the standby generator needed to be installed over the station’s discharge force main, providing additional challenges throughout the design and construction processes. The upgrade included three VFD driven dry pit submersible pumps, a complete new electrical system, submersible transducer and back up float for level control, influent grinder, magnetic flow meter, ventilation, lighting, as well as masonry and roof repairs.
Our firm 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.
Our firm 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.
