Surface Water Pilot Project - Phase 1

Update on Pilot Project (Dated May 15, 2019)

  • The volume of water imported from the City of Santa Cruz for purchase this past season was 166 acre-feet from December 2018 through April 2019.
  • The intertie was closed on April 30, 2019, and the water transfer ended for the season. It is expected to begin again in November 2019.
  • The District will continue to monitor water quality in the distribution system through July 2019.

About the Project

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 purchased excess treated surface water from the City of Santa Cruz and delivered it to homes and businesses in an isolated zone. The water purchased from the City of Santa Cruz was 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 Did It Start & How Long Will It Last?

The change of water source in this isolated area began in early December 2018 and lasted through April 2019. The last year of the pilot project is this upcoming winter. If excess surface water from the City is available, it is planned to start importing water again in November 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.

Changes in Water Quality

Water quality changes can occur whenever a change in drinking water source is made. 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 now that the isolated zone is receiving District groundwater again.
