Accokeek Elevated Water Storage Tank

Location: Accokeek, MD

Client: Washington Suburban Sanitary Commission

Accokeek Elevated Water Storage TankCCJM, as a subconsultant, designed a replacement elevated 750,000 gallon water storage tank in Accokeek, MD for the Washington Suburban Sanitary Commission.

CCJM was responsible for the topographic surveying, easement preparation, site engineering, design of a flow control valve vault, new water lines, stormwater management, and erosion and sediment control. Instead of a pressure reducing valve, a computer controlled valve (flow control valve) was installed to regulate flows and pressures at a remote location. The stormwater management plan minimized impervious cover on the site, thus allowing waiver of the quantity control requirement and use of runoff to pervious areas to satisfy the quality control requirement. CCJM presented the design at a public hearing and obtained permits from the State Highway Administration. CCJM also provided support throughout the tank construction.
