Learn How We Repair Sewer Pipes
The District uses two primary methods to repair gravity pipelines. One method is called open-trench construction and the other is called cured-in-place pipe lining (CIPP). The traditional open trench requires digging a trench for pipe removal and installation. This method is usually expensive, time-consuming, and disrupts traffic. However, open trench may be required due to the type of pipe defect. The trenchless CIPP method is preferred because it is cost-effective, less intrusive, and faster.
