Effective August 13, 2012, new tenants to a property or a realtor/listing agent representing a property will have to complete a water service application. This application requires the owner to certify that the tenant has a right to residency or that the realtor/listing agent is authorized to establish water service.  A copy of the signed lease agreement and/or listing agreement will also need to be provided and if the owner cannot appear in person with the tenant then the form will have to have a notarized signature of the owner of the property.   In addition, we will still be requiring valid picture identification, a deposit and all previous balances (if any) must be paid in full. Establishment of water may be delayed if staff needs to complete additional verification of documents.

Water Service Application

It is our goal to provide our customers with prompt, courteous and responsive customer service!

The City does require deposits on most accounts, both residential and commercial. Deposits must be paid in guaranteed funds only - NO CHECKS accepted for deposits. These deposits are refundable upon termination of the account, less outstanding charges, or after 18 months of maintaining the account in good standing at which point the deposit will be credited to the account. Allow up to three weeks for deposit refunds.

Water service connections and/or disconnections will occur within two (2) business days but no more than two weeks in advance. We are unable to accommodate same day requests. There is no weekend or holiday service.

Payments for water service may be made at City Hall at the First Floor Customer Service Counter, at a conveniently located drive-up drop box located in the City Hall parking lot, or using our new online payment service. Payments may be mailed to the City of Antioch, PO BOX 6015, Artesia, CA 90702-6015
