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) on a monthly basis

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

  • A duplicate bill can be mailed to another party, such as a tenant or property management company.

  • In all cases, the original bill is sent to the shareholder or the shareholder's agent, and 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.
