Document Description
The Proposed Project would reduce the potential for sanitary sewer overflows and leaking pipes, and reduce the risk of the loss of sanitation service resulting from failures of deteriorating infrastructure due to ground deformation, liquefaction, or lateral ground movement caused by a moderate or severe earthquake. To maintain safe and reliable sanitation service during a seismic event, the Proposed Project would also improve the ability of the Main Force Main to withstand the effects of ground deformation, liquefaction, and lateral spread hazards at the Russian River crossing. The Proposed Project would include repairing and replacing existing components of the headworks at the wastewater treatment plant, as well as repairing and replacing existing components at the 11 lift stations located within the RRCSD. Proposed repairs at the lift stations include replacing existing lift station platforms, installing new flow meter vaults, and regrading. The Proposed Project would replace the existing force main pipeline on the Beanwood, Rio Nido, and Main force main alignments. The Proposed Project would replace a segment of the Beanwood Force Main that is attached underneath the Guerneville Bridge. The Proposed Project would also replace a segment of the existing Main Force Main that crosses under the Russian River near the Vacation Beach summer crossing. The new Main Force Main pipeline segment would be microtunneled approximately 30 feet to 45 feet below the riverbed to replace the existing pipeline segment. The existing pipeline segment would be disconnected, filled with a low strength concrete mixture, and abandoned in place. Work on the force mains would improve their ability to withstand the effects of ground deformation, liquefaction, and lateral spread hazards.
