Stopping Water/Sewer Services

To stop your services with Rainbow MWD, call us one business day prior to the day you would like to end service. You will need to provide us with a forwarding address for your final bill, as well as verification of your account with your driver's license number. If you have your payment automatically deducted, when service is stopped, your automatic payment will also stop and your final bill amount will not be deducted.

Water/Sewer Billing Invoice

Your water/sewer services will be billed to you each month. The billing invoice you receive reflects the amount of water already used in the previous meter read period. Meters are ready every 27 to 33 days. Applicable fixed charges are also included and payment is due upon receipt of your invoice.

Responsibility of Owner

The water and sewer bill becomes a charge against the property on which the water and sewer are furnished and against the owner of the property. Delinquent bills from previous owners or tenants are the responsiblity of the present owner. In the process of purchasing property, the buyer should verify the status of the water and sewer account to ensure any unpaid bills are resolved during escrow.
