Salinas Valley Water Project Phase II

Print

Overview

The Salinas Valley Water Project, Phase II has been proposed by MCWRA to address water supply issues in the Salinas River Groundwater Basin. The Salinas Valley Water Project, Phase II will put to beneficial use the water right allocated to MCWRA by Water Right Permit 11043 by further developing surface water resources that will be used to offset groundwater pumping. Reduced groundwater extractions will, in turn, help to halt seawater intrusion in the Salinas River Groundwater Basin.

Project Description

The Salinas Valley Water Project, Phase II will allow MCWRA to facilitate further offsets of groundwater pumping by delivering additional surface water to the Pressure and East Side subareas of the Salinas River Groundwater Basin. Up to 135,000 acre-feet per year of water will be diverted from the Salinas River and supplied for municipal, industrial, and/or agricultural uses in the Pressure and East Side subareas, in accordance with the Technical Memorandum prepared by GEOSCIENCE Support Services, Inc. in November 2013.

The Salinas Valley Water Project, Phase II will encompass two surface water diversion points and their appurtenant facilities for capture, conveyance, and delivery of the water. Many of the details surrounding the Salinas Valley Water Project, Phase II will be evaluated in an Environmental Impact Report and a suitable alternative will be selected as result of the review process.

The capture and diversion facilities will consist of either a surface water diversion facility, similar to the existing Salinas River Diversion Facility, or Ranney® Collector Wells. The conveyance facilities will be either above- or below-ground pipelines and pump stations. In part, an Environmental Impact Report will be used to analyze the configuration, location, and physical layout of the conveyance facilities. Delivery facilities may consist of injection wells (as part of an aquifer storage and recovery system), percolation ponds, or turnouts for direct use of the water. The delivery facilities may incorporate treatment of the water or, alternatively, MCWRA may deliver raw water to be treated by the end-user in a manner suitable for the intended application (for example, agricultural versus urban).

Project Location

The Salinas Valley Water Project, Phase II incorporates two surface water diversion points, one located near the City of Soledad (called the East Side Canal Intake in the permit) and the other located south of the City of Salinas (called the Castroville Canal Intake in the permit). Each diversion point will be accompanied by conveyance and delivery facilities, the locations and termini of which will be evaluated in an Environmental Impact Report.
