City adopts Stage III of our Water Shortage Contingency Plan (see Drought Management Plan information below)

Water bill inserts are now available online:


Please call our drought hotline, 925-779-6140, for more water conservation and drought program information or to report water waste or drought violations.
On May 12, 2015, the City Council passed by resolution new drought management measures and approved implementation of Stage III of the City’s Water Shortage Contingency Plan adopted in June 2011 as part of the City’s Urban Water Management Plan:

  • During Stage III of a water supply shortage, the shortage is deemed severe at 20% to 35%, and conservation consists of allotments and mandatory conservation rules. 
  • This phase becomes effective upon notification by the City that water usage is to be reduced by a mandatory percentage. 
  • Violations of prohibited activities are punishable by fines of up to $500 for each day in which the violation occurs. 

The City of Antioch’s Drought Management Regulations and Water Conservation Mandates as adopted by City Council on May 12, 2015, create water reduction mandates of 28% for each account based on 2013 usage per month.  Your 2014 use is not being considered, as customers were under voluntary reductions at that time. 

Your two-year historical data is available on-line. To view your consumption history, scroll down to Antioch Water Account Information and click “on-line service”.

After you have registered, you can add your account number to access a history of your account transactions, and consumption data

How a Water Meter Can Track Water Use and Help You Check For Leaks:

Your water meter can tell you how much water you are using during a given time period, and can help you monitor the amount of water you use indoors and outdoors on a daily basis. It can also help you determine how much water each appliance uses, and whether you have a leak. Click here to learn How to Read Your Water Meter and Check for Leaks

In addition to the 28% reduction in water consumption, there are water uses that are now prohibited:
