Boulder homes and their sewer lines
Mapleton Hill, Whittier, Goss-Grove, University Hill and the Newlands are dense with homes from the 1880s through the 1940s, often with original clay laterals and basements added or finished later. Mid-century ranches and split-levels fill Table Mesa, Martin Acres and parts of north Boulder.
Boulder's 2013 floods pushed water and sediment into many sewer systems, and some older lines still carry damage from that event that only a camera shows.
Why Boulder sewer lines clog
Silver maples, cottonwoods and elms along older streets send roots into clay joints, so root cutting is a regular call. Hillside homes on University Hill and near the foothills can have steep laterals where solids settle. In finished basements, a backup through the floor drain or basement shower does a lot of damage fast.
Before buying an older Boulder home, a sewer scope is close to standard practice; repairs on long clay laterals under mature trees can be expensive.
