Roots under Fort Collins' big trees
Fort Collins has a lot of mature cottonwood, ash, maple and elm, often planted along the parkway right above the sewer lateral. Clay joints from the early and mid 1900s let fine roots in, and the mat they form catches paper and waste until the line stops. The usual pattern is a backup every one to two years, often in spring.
Rentals near campus
Houses converted to student rentals see more toilet and kitchen clogs and more wipes and paper towels in the main. If you're a landlord, a camera inspection after a clearing settles whether the cause was use or the pipe itself, which matters when deciding who pays.

Common questions
How often should roots be cut in Fort Collins?+
Lines with known root problems are often cut every one to two years, timed before the season they usually back up.
Can expansive soil damage my sewer line?+
Over decades, swelling and shrinking clay soil can shift older pipe joints, which then let roots and soil in.
Who pays in a rental?+
Usually the owner for roots and pipe failures; a tenant may be charged if the clog was caused by something flushed.
