Description:
The nation’s 54,000 drinking water systems and 16,000 wastewater systems are nearing the end of their useful life and need to be replaced/repaired to comply with federal regulations. Rehabilitation includes a broad spectrum of approaches, from repair to replacement, that attempt to return the system to near-original condition and performance. There are many promising rehabilitation methods and materials available in the market and trenchless technologies have moved to the forefront of sewer system rehabilitation. However, many are proprietary systems and the details of installation procedures and materials are trade secrets, limiting the ability to compare and evaluate competing approaches. The paper and presentation will provide an overview of the project and the progress to date, including an assessment of the state-of-the-art of rehabilitation practices in the water and wastewater sectors.
