Drains & sewer in Montana
Older homes in Billings, Missoula and Bozeman have clay and cast-iron laterals that collect roots from mature trees and crack with age, and deep frost means sewer lines must be buried well below the surface.

Drains & sewer in Montana: what to know
Many rural properties use septic systems, so a slow drain there may be a septic issue rather than a clog. Spring runoff from the mountains raises groundwater and tests basement drains.
A camera inspection shows whether a recurring clog is roots, a crack or a sag. City utilities maintain the public sewer, and the lateral belongs to the owner.
- Climate
- Hard freezes are a regular part of winter in Montana, so pipes in exterior walls, garages, crawl spaces and attics need protection every year, and outdoor faucets and sprinkler lines must be drained before the first freeze.
- Typical foundations
- Many rural homes rely on wells and septic systems, and basements are common in towns. Most common: basements.
Drains & sewer services
Drain cleaning
If one fixture is slow, the clog is usually in that fixture's branch line. If several drains back up at once, or the basement floor drain fills when you run the washer, the main sewer line is blocked and needs a larger cable or a jetter.
Hydro jetting
Hydro jetting cleans the full width of a drain pipe with high-pressure water, washing out grease, scale and fine roots that a cable only punches a hole through. It works best on sound pipe and is usually done after a camera inspection confirms the pipe can take it.
Sewer camera inspection
A sewer camera inspection runs a waterproof camera through the line from your house to the city main and records what it finds: roots, cracks, sags, offset joints or collapsed pipe. It's the best way to decide between cleaning, spot repair and replacement.
Sewer line repair
A damaged sewer line can be fixed with a spot repair, a trenchless liner, pipe bursting or an open-trench replacement. Which one fits depends on what the camera shows, how deep the pipe is, and what's on top of it, such as a driveway, trees or landscaping.
