Patuxent Raw Water Main. WSSC Service Area, Maryland.

WRA’s alignment study developed and evaluated 11 preliminary alternatives along eight alignments. Following screening of alternatives, seven alternatives were evaluated for economic and non-economic considerations. During the alignment investigation, WRA assisted WSSC in a community outreach program to keep residents along the alignment informed.

Design for the new pipeline includes a flow network hydraulic analysis for surge control, air/vacuum valve vaults, blow off valves, corrosion protection, and the interconnection with the existing three pipelines in the vicinity of the filtration plant. The pipeline will be installed adjacent to West Bond Mill and Brooklyn Bridge Road, in the north bound travel lane of Bond Mill Road and will cross the BGE electrical transmission main property. A phased construction of the connections to the existing pipelines is required to maintain raw water supplies to the plant.
