About the Project


In 2014, the Santa Barbara City Council directed staff to report back on a plan to evaluate the feasibility of subsurface desalination intake and potable reuse. The feasibility studies are now being developed to satisfy the requirements of the City’s amended Waste Discharge Requirements for the El Estero Wastewater Treatment Plant.  The alternative evaluations will provide useful information for a future update to the City’s Long Term Water Supply Plan, which will evaluate feasible alternatives considered in this study.


The work products for the Feasibility Studies will be developed to accomplish the following objectives:


About the Technical Advisory Panel


In 2015, NWRI formed a Technical Advisory Panel (TAP) on behalf of the City of Santa Barbara to provide expert peer review of the technical, scientific, and regulatory aspects of both the Subsurface Desalination Intake Feasibility Study and Potable Reuse Feasibility Study.  Specifically, the TAP will review the works products (i.e., draft work plan, technical memos, reports, etc.) associated with each of these studies and consider public comments on these efforts.  The TAP will also consider findings from other completed or ongoing similar efforts to develop the most informed recommendations.


The first public meeting of the TAP was held on August 5, 2015, at Santa Barbara City Hall. At this meeting, the City and its consultant, Carollo Engineers, presented the draft Work Plans on Subsurface Desalination Intake and Potable Reuse. Members of the public were invited to submit oral and written comments on the plans. The final versions of the plans, the comments received from members of the public, and documents distributed before and during the meeting are available for download from this website. Scroll down to the "Archive" section to access them. 


Technical Advisory Panel Charge


The Panel is charged with the following:


As part of the review, the TAP is expected to provide the following:


At the conclusion of each meeting, the TAP will prepare a report that provides findings and recommendations on the various technical, scientific, and regulatory aspects of their review of the work products associated with the Feasibility Studies.


Panel Members


The TAP is made up of five experts in the fields of drinking water management, desalination technology, hydrogeology, water policy issues, and other areas relevant to the study. The panel members are:
