Drought Causing Thirsty Tree Roots to Grow into Sewer Lines

Our recent drought conditions are causing an unexpected problem for homeowners: thirsty tree roots looking for water are growing into sewer lines, clogging or even breaking them.

Jeff Schnabel of Roto-Rooter in Minneapolis says of calls for sewer line problems, "I would say over the last few weeks we've had quite an uptick, maybe a 20% increase in the amount of sewer lines that are full of roots that we're seeing."

Schnabel says the most costly consequence can require excavation, which can run $2,500 to $25,000.

Schnabel recommends cleaning sewer lines every one to two years to catch root growth before it gets more serious.
