FINAL REPORT Evaluation of Seawater Desalination Projects ...

EVALUATION OF SEAWATER DESALINATION PROJECTS
PROPOSED FOR THE MONTEREY PENINSULA
• The proposed plant location
• General project implementation schedule
• Project progress to date
• Project description
• Facility operation and maintenance
• Project costs
The project description includes the following:
• Photos of pilot plant filter equipment
• An enhanced aerial photo showing key desalination plant facilities
• A general configuration of a seawater RO system train
• A table showing key intake seawater design characteristics
• A table summarizing the seawater RO basic design criteria
The Conceptual Design Report provides little information on the treated water pipeline(s).
However, a figure has been provided that shows an alignment, which is shown herein as
Figure 3.
Supports Local Area and Regional Objectives
The MBRSDP supports local area objectives by resolving the water supply deficit associated
with SWRCB Order No. 95-10 and by providing 3,000 ac-ft per year to reduce overdraft of
the Seaside Groundwater Basin. No additional supply is proposed to meet future demands in
the Monterey Peninsula area. The project would supply water to the P/SMCSD service area,
portions of the Pajaro Valley Water Management Agency service area, and certain other
areas in Northern Monterey County, in support of regional water supply objectives.
Omissions or Fatal Flaws
Additional studies are needed to determine the adequacy of using the National Refractories
ocean outfall for brine disposal and the fate of the brine plume in the receiving waters. See
also Table 11, Regulatory Requirements, in Section 7 of this report in regard to the potential
need for additional information.
