Backup supply well #1 - Corporation Yard Well

The first backup well will be located at the City’s Corporation Yard at 333 Burgess Drive. It will consist of the following components:
  1. Environmental review – Completed in June 2016. City Council approved the Mitigated Negative Declaration.
  2. Well drilling – Completed in March 2017. Well development tests confirmed that the well can produce 1,500 gallons per minute (gpm), which is half of the project goal to provide 3,000 gpm of backup water.
  3. Construction of the well facility – In progress. See below for more information.

Once constructed, water produced during periodic exercising of the well will be used for Corp Yard activities (i.e., irrigation, vehicle washing, and street sweeper) and will not normally be distributed to water customers unless there is an emergency and normal water supplies are low or unavailable.

The well facility will consist of the following components. 

  • Well pump (placed underground approximately 385 feet deep)
  • Well piping
  • Generator
  • Disinfection equipment
  • Surge control tank
  • Electrical cabinet
  • PG&E transformer
  • Fire hydrant
  • New fencing and front entrance gate
  • Site improvements (low water use, landscaping, driveway curbs)
