Summary
Desalination is being considered as an alternative supply for water in Central California. In 2009, the California State Water Resources Control Board issued a Cease and Desist Order, requiring CalAm to reduce its pumping from the Carmel River by 70% by 2016 [1]. The Carmel River is the primary water source for the region, therefore, a significant water supply alternative is needed. The central coast also relies heavily on groundwater supplies. However, problems with seawater intrusion make this a not sustainable alternative. As a result, many proposals for desalination facilities have been submitted as a possible solution to the water gap.
Facilities in the Central Coast
Existing
- Marina - Marina Coast Water District (MCWD) 0.3 MGD (not currently operational) [2]
- Moss Landing - Duke Energy, 0.48 MGD, used for power plant operations [2]
- Monterey - Monterey Bay Aquarium, 0.04 mGD, used for toilets and other on-site uses [2]
- Sand City - City of Sand City/CalAm, 0.27 MGD
Proposed
- Santa Cruz - City of Santa Cruz, 2.5 MGD [3]
- Monterey - Ocean View Plaza (private development)
- Sand City - Monterey_Peninsula_Water_Management_District_(MPWMD), 3-7.5 MDG
- North Marina - Monterey Peninsula Water Supply Project , 9 MGD
Main Issues
Energy Consumption
Rate Increase
Given the high construction and energy costs of desalination facilities, customer water bills are expected to increase as a result of desalination. For example, a typical customer should expect their water bills to increase by approximately 40% by 2018 with the approval of the proposed Monterey Peninsula Water Supply Project [4].
