Redundant Water Supply (RWS) Project

For nearly 30 years, SVPSD has tried to find a back-up source of water for the Olympic Valley should there be an emergency situation where the existing water supply is not available. In 2009, a District report completed by ECO:LOGIC Engineering (now Stantec) concluded that Martis Valley was a feasible alternative for a redundant water supply (see SVPSD – Alternative/Supplemental Water Supply and Enhanced Utilities Feasibility Study, September 29, 2009). There were other alternatives studied in these following reports: Aquifer Storage and Recovery Study, Water Treatment Plant Process and Siting study.

A series of meta-analyses of these same water supply source(s) was completed in RWS Phase I and available in the report published November 6, 2014: Phase I: Water Supply Feasibility Summary & Gap Analysis. Review of the practicable sources of a RWS were re-evaluated by Farr West Engineering and are available in the report published February 24, 2015: Phase II: Evaluation of Water Supply Source(s) Identified in Gap Analysis. The Phase III work included the 2015 Feasibility Study Update, published on November 10, 2015 and identified a preferred alternative which was published December 21, 2015 in the Final Summary Memorandum.

This project, as all municipal projects in California, will be subject to environmental and public review under the requirements of CEQA (California Environmental Quality Act). Public notices will be distributed and posted in area media outlets when the environmental review process commences. Please check this page for updates and the expected time period for CEQA.

Redundant Water Supply History

  1. September 29, 2009 – SVPSD–Alternative/Supplemental Water Supply and Enhance Utilities Feasibility Study published
  2. September 2013 – District awards a single-phase contract to evaluate possible redundant water supply alternatives to Farr West Engineering.
  3. October 2013 – In response to public concern, District nullifies single-phase contract and re-commissions a three-phase contract to evaluate possible redundant water supply alternatives. Reports to be published to contain the following:
    1. Phase I includes a summary of historical water supply investigations, including identifying under-investigated or under-evaluated options for additional analysis in Phase I.
    2. Phase II re-evaluates all water supply options identified in Phase I and perform feasibility analyses of under-evaluated options.
    3. Phase III identifies a preferred project alternative for a redundant water supply source.
  4. November 6, 2014 - RWS-PAE Phase I Technical Memo (Water Supply Feasibility Summary and Gap Analysis) is published in final form.
