Janesville's older sewer laterals
Pre-1980 housing here is 64%, above the Wisconsin figure of 58%. That ranks 6th highest of the 17 Wisconsin cities we profile. 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.
70% 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 Wisconsin: Hard water is common, and older cities such as Milwaukee are replacing lead service lines.
Permits
Excavation in the yard or street needs a permit, and someone has to call 811 first to get utilities marked.
