  • Sandbags are available for purchase in Choteau at Ace Hardware, Old West Lumber, and Teton Lumber. Teton Lumber also has pre-filled sandbags.
  • The City of Choteau will make sandbags available to residents free of charge. Sandbags will be available for pickup at the City Office from 8:00 a.m. to 5:00 p.m., Monday through Friday, excluding holidays. Sandbags are not pre-filled and persons are limited to 20 bags.
  • Material for filling bags can be obtained from the sand and gravel pile indicated on the aerial photo to the right. Please only use material from the pile directly north of Alpine Touch. Residents should bring their own gloves and shovels to fill the bags they need.
  • Note that when filling sandbags, fill them only halfway, so they are not too heavy and will stack properly. Note that when filling sandbags, fill them only halfway, so they are not too heavy and will stack properly.

Discharging a sump pump into the city’s sanitary sewer system is a big “no-no”‘. While this might seem like an easier and more attractive option than running a discharge tube from the sump pump to the exterior, it’s illegal in the City of Choteau (as in most cities), when the home is connected to the city sewer.

The main reason that cities don’t allow this is that during big storms or periods of high groundwater their sewage treatment facilities can be overloaded. When this happens, either sewage backs up into people’s homes, or the sewage water only gets partially treated before being dumped into local streams and rivers, in our case, the Teton River.

If you have this type of setup at your own home, the ‘good citizen’ thing to do is to make the sump pump discharge to the exterior. Water your trees or shrubs with it. Run it to the street, if need be.

If you need help determining if your sump pump is connected to the city sewer system, please call the City of Choteau Office at 406-466-2510. We will be more than happy to evaluate your system and offer advice to rectify the problem.
