In addition to what WaterSmart offers,  most single-family residential customers will receive quarterly Home Water Reports by email or mail. All residents have access to their Home Water Report in WaterSmart. 

With WaterSmart, you can:

  • Compare your water use to your neighbors and determine if you’re more or less efficient than similar households with My Water Score. 
  • Identify where in your house you’re using the most water — and how to reduce consumption in those places to save money. 
  • Get recommended rebates and efficiency tips customized to your water usage patterns and home profile. 
  • Find and fix possible leaks with automated alerts that let you know when your water use patterns suggest a leak. 
  • Investigate a high water bill with factors like longer billing cycles and possible leaks.  

For the most accurate results, update your household profile in WaterSmart. Your household profile takes into account information related to your household size, water-using appliances, landscaping, and daily activities.

How soon will I be notified of a potential leak? How are potential leaks identified?

Beginning in April 2023, single-family residential customers will receive courtesy alerts to be made aware of potential leaks.  
Homes with current email addresses will be alerted of potential leaks shortly after they receive their water bill. To receive alerts, accounts must have a minimum of two years of history associated with the property. You can update the email address associated with your account by adjusting the contact information in your MyCPAU account or by calling Customer Service at (650) 329-2161
Leak alerts are sent when monthly consumption exceeds:  

  • 750 Minimum Gallons Per Day (GPD) 
  • 200% increase over the seasonal high from the previous two years
