Crystal Rock Force Main. WSSC Service Area, Maryland.

WRA prepared contract documents for a 3,400 linear foot, 36-inch wastewater force main for WSSC’s Crystal Rock Pumping Station in Montgomery County.

WRA prepared a Memorandum for WSSC listing three alignment options. The final route was primarily through County public right of ways with three private properties. Force main design of the 36 inch pipeline included a flow network hydraulic analysis, air/vacuum valve vaults, blow off valves, traffic control, permitting, and the final connection detail into an existing sanitary manhole.
