Suspect a water leak? Click here to learn the right steps to help determine if you have a leak and if it is inside or outside of your home. Thank you in advance for being mindful of protecting our most precious resource - water. The City does not perform leak detection services for customers.


Reading your water meter will tell you how much water you're using and whether you have a leak. Most meters are located near the curb in front of your home or business, under a concrete lid.

Billing units are in hundred cubic feet "HCF"; to obtain HCF, read all digits except the last two. Subtract your last reading from the current reading to determine your use in hundred cubic feet. To convert your usage to gallons, multiply by 748 (one hundred cubic feet (1 HCF) equals 748 gallons).


The City provides customers a water conservation survey at no additional cost. These surveys include:

  • An analysis of your water usage,
  • An explanation of how to read your meter,
  • Suggestions for you to follow to detect a leak and adjust your irrigation systems, and
  • Helpful information and tips on conserving water.

For more information or to sign up for a survey, please contact the City’s Public Works Department at (805) 449-2499.
