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.
CP provided support to the Altoona Water Authority in the development and selection of a Guaranteed Energy Savings Agreement to select a Firm/Team who would upgrade specific aspects of both the Easterly and Westerly Wastewater Treatment Plant Facilities. This work focused on the development of Anaerobic Digesters to replace the Authority’s existing aerated sludge holding tanks.
The selected firm developed a Preliminary Audit Report which led Altoona to a $36.5M project to develop a High Strength Waste Receiving station, two Anaerobic Digesters, and a Sludge Dryer.
CP worked with the Bradford Sanitary Authority (BSA) in support of the PennVEST funding by completing a Second Opinion Project Review (SOPR) package on the preliminary design prepared by Gannett Fleming, Inc. This report included questions and suggestions, which lead to the ultimate final design. Additionally, CP was again hired to provide operations support and expert witness consulting on the issues associated with the Contract Closeout of the Construction Project.
CP was also hired to continue the work of Operations Consulting and Expert Witness Testimony. The details are confidential.
CP also provided an improvement study for the SBR Decant Control System.
CP was retained to provide engineering services for the Construction related services of the PA DEP Small Projects Grant for the 2019 McAlisterville Area Joint Authority (MAJA) WWTP Rehabilitation Project. CP led an effort to complete a Master Plan for the Authority’s Water System as part of a larger effort to qualify for state and local financial aid. The MAJA qualified with a Low to Moderate Income Designation and has received funding for two projects to date – the Tennis Spring Rehabilitation Project and the Well No. 4 & Storage Tank Project.
The MAJA was reissued its Water Allocation Permit in September 2018. As part of that Permit, the Authority is required to conduct a 10-year flow study on the Tennis Springs. During investigation of the Springs, it became apparent that a considerable amount of flow was bypassing the Spring Box and would not be metered as part of the flow study. As part of the effort to comply with the PA DEP Requirements, a Flow Study Outline was submitted which outlined the current status of the Tennis Springs (No. 1 & No. 2) and proposed to implement the construction of a flow meters at those springs. It was our suggesting that the actual Springs be rebuilt from their 1930 era construction to completely capture the spring flow prior to implementing the flow study. Ultimately the Study led to a Preliminary and Final design which became the Tennis Spring Rehabilitation Project.
CP continues our Retainer Support to MAJA and has also providing Engineering Support toward a Statewide DCED Competitive Grant Application – 2022 for the Well No. 4 & Storage Tank project.
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 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 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 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.
Developed the preliminary engineering design documents, and completed the required permitting for the wastewater facilities which were required as part of the Boyd’s Bear redevelopment project in Greenmount, PA. The initial work consisted of the design and construction of two pump stations and a 0.150MGD Sequencing Batch Reactor (SBR) WWTP, with tertiary filtration and UV disinfection. The treatment plant was designed in a modular fashion such that future flows up to 0.300MGD can be treated as additional development on the project site is completed. Prepared the Water Quality Management Permit for the proposed design of the facilities in addition to the initial National Pollutant Discharge Elimination Permit (NPDEP).
