Report
RECOMMENDATION:
It is recommended that the Monterey County Water Resources Agency Board of Directors:
Receive the New Sources Water Report for the Castroville Seawater Intrusion Project.
SUMMARY/DISCUSSION:
The Monterey County Water Resources Agency (MCWRA) and Monterey One Water (M1W), formerly known as Monterey Regional Water Pollution Control Agency (MRWPCA), entered into an Amended and Restated Water Recycling Agreement (Restated Agreement), which included consideration of the financing, design, construction, operation, maintenance, and replacement of New Source Water Facilities to provide approximately 4,381 acre-feet per year (AFY) of additional recycled water to MCWRA for use in the existing Castroville Seawater Intrusion Project (CSIP), a coastal irrigation project . In addition, M1W would be provided approximately 4,320 AFY of new source water to supplement the Pure Water Monterey Groundwater Replenishment Project which has been developed to provide drinking water.
MCWRA currently obtains water from three sources: recycled wastewater from the Salinas Valley Reclamation Project (SVRP) (which has included industrial wastewater since 2015), surface water from the Salinas River Diversion Facility (SRDF), and water from CSIP supplemental groundwater wells. The objective of obtaining new source waters is to reduce the use of water from CSIP groundwater wells ("supplemental wells").
In 2017, MCWRA and M1W contracted with Raftelis Financial Consultants, Inc. (Raftelis) to conduct a New Source Waters Study (Study). The purpose of the Study, and the report, is to provide a cost analysis for the operation, maintenance, and capital costs for New Source Water Facilities to determine specific rates and charges for final consideration. Through discussions with MCWRA and M1W the new source waters evaluated in this Study were narrowed to Blanco Drain and R...
