Billing & Payment


The following information is provided to help you understand the water billing and payment policies of Atascadero Mutual Water Company (AMWC).


  • Bills are sent to shareholders (property owners) and/or their Authorized Agents on a monthly basis (Mail or E-Bill)

  • Meters are read between the 14th and the 19th of each month

  • Tenants can receive paper bills mailed to the service address, addressed to OCCUPANT, if authorized by the shareholder

  • In all cases, the shareholder is ultimately responsible for payment of all charges

Water Rates

AMWC's water rates consist of two parts:

  • a base fee that varies by meter size or number of units, and

  • water use rates that increase as water use increases

See Rates & Charges for detailed rate structure. Rates and collection policies are subject to change without notice.

Due Dates, Late Charges, Past Due Bills

AMWC does not assume responsibility for late or non-delivery of water bills by the post office. Bills are scheduled to be mailed on approximately the 25th of each month; if you have not received your bill by the 1st of the month, please contact our office to check your account status.

All bills are payable upon receipt and are past due if unpaid by the 22nd of each month.  Late fees are assessed on the 6th of each month for accounts with an unpaid balance. Click here to view AMWC's Late Fee Policy.

Water service will be shut off to those customers who do not pay the past due balance on their water bill by the Shut-off Date shown on the Shut-off Notice, and shut-off fees will be assessed. Click here to view AMWC's Shut-off Policy.

Property owners may contact AMWC's business office to request a review of their account by AMWC staff or AMWC's Board of Directors.

Payment Extensions

AMWC does have a payment extension policy that may be available if a shareholder needs additional time to make a payment. All requests for extensions must come from the property owner prior to shut-off deadlines. Because the shareholders are ultimately responsible for payment of the water charges,  AMWC does not honor requests for payment extensions from tenants.  

High Use Adjustment

For qualifying high-use adjustments, the billing adjustment will be 50% of the difference between the high-use water bill and the average-use water bill. To see if you qualify for a leak adjustment, please review the policy and complete a High-Use Application Form found on the FORMS page.
