Billing & Disconnection

All customers are billed as part of one of six billing cycles, spread throughout each month based on Meter Reading Routes and geographic location. Your should receive your bill approximately the same time each month. However, should you move, your billing date may change depending on what route your new address falls under. If you do not receive a bill, please contact our office to obtain your account status.


Customers are billed based on usage only. We never bill for water or wastewater service which has not been used yet. Please look at our current rate schedules for more information on billing charges. Final payments are due 25 days from the Bill Date on your bill. Bills paid after the due date listed on the bill will be subject to a late fee. Bills not paid by close of business on the 25th day are subject to a non-payment fee and will be scheduled for disconnection.

Most accounts are disconnected for one of two reasons:

  1. Customer Request
  2. Non-Payment

Disconnection requests must be made in person at the CMD Office, 155 Wylie Street (Great Falls customers please visit Town Hall, 810 Dearborn Street). Requested disconnections will be done at the earliest convenience of our meter or maintenance crews.

Accounts scheduled for disconnection for non-payment or returned payments are subject to a Non-Payment Fee, which must be paid in addition to the regular bill. If you request restoration of service between 4PM and 9PM, an additional “after hours fee” will be added to your current charges.

Disconnection schedules are created in advance, and information on projected disconnection dates is available by contacting the CMD Office.

We do not restore services between the hours of 9:00 PM and 8:30 AM.


Payments are returned for various reasons. The two most common reasons are:

  • Insufficient Funds
  • Closed or Invalid Accounts

If a check or online payment is returned for any reason, service will be immediately terminated until all charges are paid in full. Returned payments are subject to a NSF fee in addition to the regular monthly bill and other assessed charges.

Returned payments cannot be made online. They must be paid in the office by cash or money order only.

Any account holder with three or more returned payments for any reason will be noted as “cash only” and will no longer be able to make payments online or by check.


Any account disconnected three or more times for non-payment or returned payments may be subject to an additional deposit, required before service can be restored. CMD and CSD reserve the right to charge up to 1.5 times the amount of the highest monthly bill.

Additional deposits must also be paid in our office.

All Fees and amounts owed must be paid in full before we can restore service or remove your account from the disconnection queue.
