City of Port Angeles, WA: Large-Diameter Bundled Slipline for a CSO Diversion Project
The City of Port Angeles required three pipelines to deliver effluent sewer to a water treatment plant as part of a combined sewer overflow (CSO) diversion project. An abandoned existing partially buried 48-in. reinforced concrete waterline that runs the length of the Port Angeles waterfront was used to rout the required force main pipelines to reduce disturbance to sensitive areas including Native American burial grounds, protected coastal species habitat, and high-quality wetlands. A pipe bundle consisting of two 14-in. and a single 30-in. pipe were sliplined through the existing waterline using a horizontal directional drill rig. Complex transitions from grade to subsurface elevations in tidally influenced zones of protected shoreline complicated the design and installation at the slipline pull and insertion pits. The 4,500 lineal ft slipline design is detailed along with specific challenges that required unique solutions both in design and during the construction.
