Central Coast Blue Project

Central Coast Blue Project

The proposed project is a regional advanced purified water project intended to enhance supply reliability by reducing the Santa Maria Groundwater Basin's (SMGB) vulnerability to drought and seawater intrusion. The project would involve injection of advanced purified water into the SMGB via a series of injection wells installed at various locations to create a seawater intrusion barrier. Water for the project would be sourced from two of the region's wastewater treatment facilities - the Pismo Beach Wastewater Treatment Plant (WWTP) and the South San Luis Obispo County Sanitation District (SSLOCSD) WWTP. Prior to injection to the SMGB, water would be treated to an advanced level of purification at a proposed ATF constructed at Assessor's Parcel Number 060-543-016 in Grover Beach. The proposed ATF would treat a combination of flows from the Pismo Beach WWTP and flows from the SSLOCSD WWTP for injection in the SMGB and/or for agricultural irrigation. In addition to the ATF, project components include an advanced purified water storage tank, an equalization basin, a pump station, distribution pipelines, injection wells, monitoring wells, one new production well, and potential agricultural irrigation pipelines. The project would alter the pumping regime of existing, operational production wells in the project area and would include construction of one new production well to optimize groundwater production in the area. Potential environmental effects include, but are not necessarily limited to, impacts related to air quality, biological resources, cultural and tribal cultural resources, energy, greenhouse gas emissions, hazards and hazardous materials, hydrology/water quality, land use, noise, and transportation.
