Camden County Municipal Utilities Authority
Operations Assistance/Performance Improvements
D&B/Guarino has provided annual general engineering services to CCMUA’s 80 million gallons per day (MGD) Delaware No.1 Water Pollution Control Facility (WPCF) for over two decades. Engineering services include specific tasks to be conducted on an annual basis, such as the preparation of a customized renewal and replacement report that incorporates condition codes, recommended actions and established costs for major plant equipment and buildings. D&B’s operations assistance, such as improvement recommendations for the primary and secondary settling tanks and aeration tank operations led to increased plant performance, improvements in the plant effluent and reduction of odors. D&B/Guarino also provided assistance with the development and implementation of CCMUA’s award-winning Environmental Management System.
Cross Keys Road Pump Station
D&B/Guarino designed a new 7.3 MGD pump station to transfer wastewater from the Atlantic Basin portion of Camden County to the CCMUA Wastewater Treatment Plant that discharges into the Delaware River. The design services included site investigation and data collection, review of aerial photographs to develop alternative sites for the pump station, and a topographic survey to develop a base plan for the pump station site 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, construction materials, preliminary plans, construction cost estimate, construction schedule and needed permits. This work was followed by developing bid documents and providing bid and construction design services during construction.
County Force Main Extension
D&B/Guarino provided planning, design and design engineering services during construction for the installation of 40,700 linear feet of 30-inch ductile iron force main and 4,200 linear feet of 30-inch PVC gravity sewer extension. The project increases system capacity by directing an additional 7.5 MGD of sewage to the CCMUA’s existing Delaware No.1 WPCF, ultimately allowing for the further development of the southern portion of Camden County.
Sludge Drying Factory
D&B/Guarino provided planning, design and construction management services for a 220 wet tons per day indirect sludge drying facility, as well as a biofilter and carbon filter odor control system. The project successfully minimized sludge disposal and odor generation at CCMUA’s Delaware No. 1 WPCF.
Combined Sewage Overflow System Improvements
Camden and Gloucester, NJ
D&B/Guarino provided construction management services for improvements to the combined sewer overflow (CSO) systems within the Cities of Camden and Gloucester. D&B/Guarino managed construction and startup of netting facilities and consolidation of outfalls for three separate CSO improvement projects totaling $20 million.
AD/CPH Facilities at Delaware No.1 Wastewater Treatment Facility
D&B/Guarino was retained to provide balance-of-plant design, including the re-purposing of existing wastewater treatment facility (WWTF) systems, and assembled the overall design and specification package for the $69 million Anaerobic Digestion/Combined Heat and Power (AD/CHP) project. The new facilities convert 44 dry tons of biosolids to biogas per day, which will then be used to produce up to four megawatts of electricity to operate the WWTF. D&B/Guarino also provided construction management services, overseeing the installation and testing of the equipment and systems and coordinating between plant operations and general contractors.
Biofilter Odor Control System
D&B/Guarino designed upgrades to the multiple existing chemical scrubber systems servicing the sludge processing and storage facility. The upgrade included the design of a single 120,000 cubic feet per minute biofilter system to replace the chemical system.
Preliminary Treatment Facility Influent Structure Rehabilitation
After evaluating deteriorating concrete and damage caused by a hydrogen sulfide environment, D&B/Guarino designed the repairs to the facility, which includes the installation of an 80 MGD sewer bypass system; 55,000 square feet of concrete cleaning; repair and coating; replacement of damaged stop logs; and rehabilitation of the sluice gates.
