FINAL for 3/27/08 Meeting | MPWMD Comparative Matrix, Part II, Desalination Projects | ||||
DECISION ELEMENT | Seawater Conversion Vessel | ||||
PROPONENT/SPONSOR | Water Standard Company | ||||
PROJECT DESCRIPTION | Completely self contained
seawater desalination treatment plant installed on a ship. Electrical energy
and propulsion will be provided by gas turbine engines fueled with
Biodiesel. No seabed intake or outfall
lines are required. Water produced on
the ship will be shuttled to shore as
required. Facilities required to distribute the water to customers on shore are unknown at this time but could be assumed to be similar to those required in the other alternatives. Size of project is unknown but assumed to be 20 MGD (approx. 22,000 AFY). Costs provided for 18 MGD project yield (approx. 20,000 AFY). |
||||
Pilot Project | None planned. State currently requires pilot plants but that requirement was written around land based facilities. WSC sees no need to pilot the process since we have over 2,000 ships currently successfully treating seawater. Issues needs to be discussed with the State DOHS. | ||||
PROJECT YIELD | 10 MGD - 75 MGD. Actual yield to be based on commitments of purveyor customers | ||||
Comply with Order 95-10? Water for Seaside Basin? | Yes, and can easily meet all future needs | ||||
Future Monterey Peninsula Needs? | Could easily be sized for all future needs | ||||
Future Non-Monterey Peninsula Needs | Could easily be sized for all future needs | ||||
TOTAL YIELD | Could easily be sized for all future needs | ||||
Yield Phasing to Monterey Peninsula | Phasing will be based on demands. Larger size initially is better. | ||||
PROJECT COST | Costs in 2006-2007 dollars for 18 MGD (approx 20,000 AFY) project provided by WSC | ||||

Cost of Water ($/AF) | Cost of water produced on the SCV estimated to be less than $1,000 AF. Costs for required distribution and pumping unknown. B-E/GEI: $1,550 (subsidized fuel) - $1,770 (unsubsidized fuel). Based on 18 MGD yield (approx. 20,000 AFY). | ||||
Impact to Cal-Am Bill | N/A | ||||
FINANCING ASSUMPTIONS | WSC funding can be used. Prefer a public private partnership with MPWMD | ||||

SITE CONTROL | |||||
Confirmed site? | Location doesn’t really matter for the SCV itself. Shuttle ship off loading site must be selected depending on who the customers are. | ||||
Alternative sites and projects? | No restrictions. No land required. SCV can be located anywhere. | ||||
OPERATIONS/OTHER | |||||
Technical, Managerial and Financial Capabilities (TMF) to meet DHS standards | Assume implementing entity would operate desal plant with MPWMD oversight. | ||||
