Great Falls's older sewer laterals
Pre-1980 housing here is 73%, above the Montana figure of 50%. Clay pipe lets roots in at the joints, cast iron scales and cracks, and the line from the house to the street belongs to the homeowner in most places.
60% of homes are detached houses with their own lateral, so a backup that keeps coming back is usually worth a camera inspection rather than another snaking.
In Montana: Many rural homes use private wells and septic systems.
Permits
Excavation in the yard or street needs a permit, and someone has to call 811 first to get utilities marked.
