Pump Station 4 Force Main River Crossing

The existing sewer force main under the Wishkah River failed, and the City of Aberdeen needed it back before sewage reached the river. Cannon installed a new 12 inch HDPE SDR 11 force main 600 feet under the river by horizontal directional drilling, so the riverbed was never opened and surface impact stayed minimal. Cannon ran wireless steering to hold line through brackish water interference, coordinated the work with the City, WSDOT and the general contractor, and finished ahead of schedule.
