As part of the recovery and reentry process, County of Monterey crews are inspecting utilities and infrastructure in and around previously flooded areas. After the Pajaro River floodwaters receded, it was discovered that the Pajaro County Sanitation District (PCSD) sewer force main is compromised at the Highway 1 Bridge where the Pajaro River floodwaters eroded the levee under the bridge.
This force main (pressurized pipeline) serves the communities of Pajaro, Bay Farms, Fruitland Avenue, and Las Lomas. Under normal operations, all the sewage from these communities goes to one single pump station then into this single force main, which sends sewage to the west approximately 2 miles along the levee and ultimately to the City of Watsonville Wastewater Treatment Plant.
The sewer force main is the black colored high density polyethylene pipe (HDPE) in the pictures. (The white colored and blue colored PVC pipe are unidentified pipelines.)
Public Works, Facilities and Parks’ Special Districts staff quickly prepared a design for emergency temporary repair and called in contractors to begin repair work. This repair work is underway with the goal of having sewer service back online with the week.
To handle the sewage currently, Special Districts staff have been coordinating more than a dozen sewage pumping trucks, cycling the trucks around the clock to collect and truck the sewage to the treatment plant while the force main and pump station are offline.
