August 26, 2013 (La Mesa) – The City of La Mesa began a process that minimizes root intrusion in its underground sewer system.  Roots can enter the sewer through joints in older sewer pipes.  Performing the sewer root foaming work is contractor Pacific Sewer Maintenance Corporation.

Work began on August 22, 2013, and it will last between 30 to 45 days.  There should be no disruptions to individual or business sewer services.
