Existing Connections Billing For information about paying your semi-annual sewer bill, contact the Finance Department.
Verifying a Connection
Using the civic platform, Buildingeye, you can research sewer connections and print the record drawing(s). There is no need to login or create a new account. Search by address or by zooming in to a neighborhood and select the icon on the parcel.
Contact the Wastewater Division at 406-552-6600 to request a connection record for the property.
Please note that receiving a sewer bill does not necessarily indicate that a property is connected to sewer.
New Connections Connect on Sale Ordinance The city requires that all properties within city limits which have sewer available be connected upon sale or transfer of the property. For more information, please visit our Connect on Sale page.
Pay any sewer connection fees. Fees are calculated by city engineering and vary depending on the building's water meter size, location, SIDs, and any previous contributions to the cost of the main. Call 406-552-6635 or fill out the Sewer Connection Fee Form to request a fee calculation.
Hire a contractor who is licensed and bonded for excavations.
The contractor will need to purchase a permit from city engineering. Permit fees are set by city ordinance and are listed in the current Fee Schedule.
The contractor will contact city engineering to arrange for inspections, and a record drawing of the connection will be made.
Connecting Outside City Limits
Outside of city limits, more steps will be required before you can connect to sewer. Contact Development Services at 406-552-6635 or by email for information.
