Sander Engineering Corporation (“SEC”)has rehabilitated approximately 150,000 linear feet of sanitary sewer in recent years to minimize groundwater and surface water infiltration. Sanitary sewers have ranged in size from 8-inch to 36-inch diameter pipe. Existing pipe materials have been ABS Truss, clay, asbestos cement, concrete and PVC pipe. Typical problems being deteriorated pipe, cracks, joint misalignment, sages, root intrusion, various forms of blockages and poor installation. The primary method of rehabilitation has been Cured-In-Place Pipe (CIPP) along with Pipe Bursting, Slip-lining and Remove and Replace. Concurrent with the sewer pipe rehabilitation, SEC typically rehabilitates associated manholes with coatings/liners to address groundwater infiltration and the installation of inflow protectors to minimize surface water intrusion. We have performed this service for many of our utility district clients, the City of Houston and the City of League City.
