The Salton Community Services District is proposing improvements to the existing wastewater collection system at Desert Shores, California. These improvements, replacing portions of the existing collection system and simplifying the pumping infrastructure, will address the problem of saltwater infiltration into the collection system and the percolation of brackish treated wastewater into the groundwater below the wastewater treatment ponds. The sewer replacement is designated to resolve environmental impacts to the groundwater down gradient from the ponds.
