Are there restrictions on when I can water my lawn?

No, Dillon currently does not have any watering restrictions. We do, however, suggest that our customers water their lawns during the cooler times of the day—6:00 a.m. - 11:00 a.m. or 5:00 p.m. to 10:00 p.m.—to get the best results from their water usage.

How do I open or close a utility account?

Moving In:  Please contact our customer service representatives at (406)683-4245. We will need your name, telephone number, name of spouse or roommates, mailing address, and landlord information to establish service. You will also be required to pay a deposit ($50 for homeowners, $100 for renters) in the form of cash, check, money order or cashier’s check.

Moving Out: The person whose name appears on the utility account is responsible for notifying us of the move out date as well as a forwarding address. A final billing will be mailed after the account is closed. We are unable to make billing adjustments for late notification.
