Old laterals, older trees
Mapleton Hill, Whittier, Goss-Grove and University Hill have homes from the late 1800s through the 1940s with clay laterals running under yards shaded by silver maples, elms and cottonwoods. Fine roots enter at the joints, and in a dry climate a slightly leaking joint is one of the best water sources around.
Managing it without losing the tree
- Cut roots on a schedule, before the season your line usually backs up.
- Jet after cutting if fine root hair regrows quickly.
- Scope to find the joints that are failing worst.
- Repair or line those joints so the tree and the sewer can coexist.
Hillside laterals
Homes on University Hill and near the foothills can have steep laterals. Roots plus a change in slope give solids a place to collect, so these lines often need cutting and jetting together.
