Baltimore's sewer system includes thousands of miles of clay pipes installed in the early 1900s. These pipes were not designed to last a century. Freeze-thaw cycles crack the clay, and tree roots from the city's mature urban canopy invade those cracks. Neighborhoods like Hampden, Roland Park, and Guilford have streets lined with 80-year-old oaks and maples. The roots grow toward the moisture inside sewer lines and create blockages that cause backups during heavy rain. Combined sewer systems in older areas of the city also overwhelm during storms, pushing sewage back into homes through floor drains and basement fixtures.
