Camp Fretterd is home to the Maryland National Guard and the Maryland Emergency Management Agency (MEMA). Many areas of the campus experienced low water pressure, and GMB’s hydraulic modeling determined that some areas could also experience insufficient fire flows. MES tasked GMB to design a new water booster station to provide additional pressure and designed new water mains to complete a fire loop in the western sections of the campus. GMB also designed a new wastewater treatment facility to replace existing on-site septic tanks. MDE imposed stricter limits on nutrient discharges to the drain fields which required a higher level of treatment. GMB designed a state-of-the-art MBR treatment system to achieve the new discharge limits. The new system included a three-stage activated sludge process followed by an ultrafiltration (UF) membrane to separate the bio-solids from the final effluent. The MBR treatment system will be housed inside a pre-engineered metal building which also includes screening, chemical addition, a back-up emergency generator, and a small workstation for MES’s operations staff.
