Surface Water Pilot Project - Phase 2

Update on Pilot Project (Dated 2.13.2019)

  • The volume of water imported from the City of Santa Cruz for purchase  was 27 acre-feet in December 2018 and 28 acre-feet in January 2019.
  • On February 6th, the City of Santa Cruz requested that the District reduce flows from the intertie by approximately 50%.  This was due to changing North Coast stream fish flow goals triggered by winter storms.  
  • District staff is monitoring the increasing water quality trends related to the formation of disinfection byproducts related with the imported surface water.


What is it?

The Surface Water Pilot Project is part of the District’s Community Water Plan, our multi-pronged approach to restoring the groundwater basin and preventing further seawater intrusion. For the first winter, the District will purchase excess treated surface water from the City of Santa Cruz and deliver it to homes and businesses in an isolated zone.  The water purchased from the City of Santa Cruz will be water treated at the City’s Graham Hill Water Treatment Plant prior to entering Soquel Creek Water District’s distribution system. All transferred water is the same drinking water supplied to customers of the City of Santa Cruz Water Department.

When will it start and how long will it last?

The change of water source in this isolated area began in early December 2018 and will last possibly through April 2019. Possibly through April 2019. Some terms and conditions include Loch Lomond Reservoir being full and is spilling or anticipated to be full by April 1, aquatic flows meet requirements, and the City of Santa Cruz is not in a mandatory curtailment.  To see the weekly water conditions of Santa Cruz's water system, click here:

What might be some changes in water quality?

These changes are not expected to affect the safety of your drinking water in that area but you may see changes in water hardness and water aesthetics including discoloration, taste, chlorine odor, and turbidity. 

Changes in hardness: The City of Santa Cruz's water is less hard than the District's. Last year, the City's water hardness averaged 164 parts per million, or 9.6 grains per gallon. The District's water in the isolated zone averaged 265 parts per million, or 15.5 grains per gallon.  You may want to adjust the setting on your water softener.
