Trevose Road & Kelvin Avenue Water & Sewer Upgrades

City of Philadelphia, Philadelphia County, PA

Provided engineering design services for the construction of 2,179 LF of new sanitary sewer and 1,535 LF of water main relay along Trevose Road near the Poquessing Creek. The project goal was to construct new sanitary sewer for residents with failing on-site septic systems. To facilitate this work, extensive survey and elevation analyses were required to design a system that could accommodate gravity tie-in to the new system by as many residents as possible.

Because of poor soils indicated by the geotechnical analysis, helical piles were recommended as support for portions of the stormwater and sanitary sewer infrastructure. An outfall at the Poquessing Creek also required coordination and permitting with the Pennsylvania Department of Environmental Protection (PADEP).  Because of the resulting extensive construction on Trevose Road, a detour had to be properly permitted through PennDOT and the Streets Department. Trevose Road also required partial regrading and the addition of drainage structures to alleviate localized flooding issues. As part of Colliers Engineering & Design’s services, final plans and specifications/quantity estimates were also prepared.
