Cal Am Water
Monterey Peninsula Water Supply Project
Phase 2: Ground Water Recharge



In collaboration with stakeholders in the Monterey Peninsula region, the CPUC is seeking to support solutions to water constraints in the region via its regulation of Cal Am Water. As part of Phase 1 to develop a Monterey Peninsula Water Supply Project, parties identified various scenarios for developing a desalination plant in the region.   

On April 18, 2016, as a result of delays in the environmental review for Phase I, sixteen parties filed a Joint Motion requesting the CPUC first authorize a Phase 2 Ground Water Recharge project.  


Scope of the Proceeding

On April 25th, the CPUC issued a Ruling approving the motion to commence Phase 2. The purpose of Phase 2 is to consider Ground Water Recharge (GWR) as a possible component of the water supply portfolio for Monterey. Phase 2 will also determine approval for a purchased water contract for GWR and any Cal Am infrastructure necessary for its use.

Cal Am Proposal

On May 9, 2016, Cal Am submitted Joint Testimony, along with the Monterey Peninsula Water Management District and Monterey Regional Water Pollution Control Agency, which supported CPUC approval of a Ground Water Recharge purchased water contract and approximately $50.3 million in associated facilities.

CPUC Proposed Decision

On August 12, 2016, the CPUC issued a Proposed Decision.  


Evidentiary Hearings were held at the CPUC on May 26-27, 2016.  

A Public Participation Hearing is set for September 1, 2016 in Monterey.


ORA Position

ORA supports CPUC authorization for Cal Am to enter into a water purchase agreement for Ground Water Recharge (GWR). GWR presents a viable water supply opportunity that is consistent with the state’s goals for recycled water.   

However, the CPUC should not authorize the construction of proposed facilities, such as water pumps and pipelines, as they are not necessary for Cal Am to receive Ground Water Recharge water. Such facilities may require modified engineering, depending upon the Phase I results of implementing a desalination solution, which is still to be determined.
