Improvements to date

Good news! Del Oro has completed installation of a new generator for Larkspur Meadows District to provide back-up power to keep water flowing during Public Safety Power Shutoffs and other power outages. The new generator is automatic and replaces an old engine that had to be manually hooked up during a power outage. This new system allows us to easily continue serving our customers during these events.

The new meter installed at Black Butte District:


All meters in Black Butte District have been replaced with new meters. As part of the meter exchange project, all gallon meters have been replaced with cubic foot meters.


All new piping has been installed between the pump and pressure tank. DOWC crews have also installed new pressure tank flow and hour meters, as well as a pressure release valve.

  2. The established billing cycle for water used is monthly.
  3. The opening bill for meter service, except upon conversion from flat rate service, shall be established after the first day of any year, the portion of such annual charge applicable to the current year shall be determined by multiplying the annual charge by one three-hundred-sixty-fifth (1/365) of the number of days remaining in the calendar year. The balance of the payment of the initial annual charge shall be credited against the charges for the succeeding annual period. If service is not continued for at least one year after the date of initial service, no refund of the initial annual charges shall be due the customers.
