Mission Statement:


The Seeley Lake Sewer District was formed in 1992 to assist the community in determining the need and cost for a centralized sewer system. The District’s goals are to:

1) Identify grant opportunities and other funding strategies that support an affordable sewer project;

2) Address water quality concerns from high density septic system influence;

3) Facilitate solutions related to design, construction, acquisition or financing needs for proposed improvements.

Recent Sewer District News:

  • The Seeley Lake Sewer District Board of Directors voted September 14th to accept the revised funding offer provided by USDA Rural Development in response to the District’s request for additional funding. The District’s project for Phase 1 improvements will now be fully funded as a result of this action.

A sewer for Seeley Lake:

Your water. Seeley’s future. Your Choice.

This autumn, Seeley Lake property owners will determine whether to construct a sewer system and wastewater treatment facility in our community. Construction would be financed with a combination of grant funds and special assessment bonds. Seeley Lake property owners within the sewer district would each pay an additional assessment on their annual property tax bills to service the debt on those bonds and to cover the cost of operation and maintenance of the system. Updated cost estimates will be published in August of this year, in advance of the time this fall when property owners will have to choose whether to support the sewer project.

Studies of Seeley Lake’s groundwater indicate significantly elevated nitrate and chloride levels in the groundwater. Those studies draw a clear link between the location and density of septic systems in our community and the location and degree of the problem.

The contaminants pose a health hazard to people drinking untreated well water. Consumption of nitrates can cause methemoglobinemia (a potentially serious blood disorder), cancer and birth defects in humans. High nitrate and chloride levels additionally may indicate the presence of disease-causing organisms in the groundwater.

At the same time, the lake at the heart of our community is suffering from elevated and rising levels of nutrients (phosphorous and nitrates). We’re seeing a growing problem with algae blooms in the lake and the Clearwater River downstream, occasionally with toxic blue-green algae. Over time, this ongoing degradation of water quality may impact the recreational value of the lake, which in turn impacts our local economy. 

This growing, community-wide problem can only be addressed with a community-wide solution. That’s why voters in Seeley Lake approved the formation of the Seeley Lake Sewer District. Led by a local staff and local volunteer board of directors, SLSD has spent years studying the need and developing a comprehensive, staged plan for a sewer system and treatment facility.

Notice of a protest period will be mailed to all property owners this autumn (exact date to be determined). If you support construction of the sewer system and treatment facility, you needn’t do anything. If you oppose construction, you will have 30 days to file a protest at that time. The mailing you receive will include detailed instructions.

Residential property owners will have one right of protest per parcel they own; businesses (which will pay double the residential sewer rate, should the sewer be built) will have two rights of protest per parcel they own. All property owners in all four phases of construction will have a right to protest during this autumn 2017 period. At the conclusion of the protest period, if valid protests are received from property owners who collectively bear less than 50 percent of the cost of the system, then the sewer district’s board of directors may proceed to sell bonds, levy assessments, and undertake construction of the sewer system. If that occurs, all properties within the district — regardless of protest status — will be able to connect to the sewer once it is constructed. 

If valid protests are received from property owners who collectively bear more than 50 percent of the cost of the system, the board of directors cannot proceed to finance and construct the system as planned.

Prior to the notice and protest period, we encourage you to discuss this issue with your neighbors in Seeley Lake. If they have questions, you can point them to for more information. They (and you) can also speak with district staff or connect with board members by calling (406) 677-2559; emailing us at; or visiting the office at 3360 Highway 83 North, open weekdays between the hours of 10 a.m. and 12 p.m.
