Charlotte Water Sanitary Sewer Rehabilitation Program
CHA provides Sanitary Sewer Evaluation Survey (SSES) and Flow Monitoring and Sewer Rehabilitation to Charlotte Water. Since 2001, we have installed 63 permanent flow meters and 16 rain gauges, as well as over 2,000 temporary flow meter installations. We have conducted CCTV review and analysis of over 5 million feet of sewer, smoke testing of 16 million feet of sewer, inspection of over 115,000 manholes, and acoustical inspections of over 4.1 million feet of sewer using the sewer line rapid assessment tool (SL-RAT). We have also carried out CIPP lining of over 3 million feet of sewer, ranging from 8 to 78 inches in diameter, and pipe bursting over 50,000 feet of sewer. Over 75,000 manholes and thousands of service laterals have also been rehabilitated.
Charlotte Water Sewer Rehabilitation Projects:
- 78-Inch Sugar Creek Sewer Rehabilitation which involved lining 2,700 feet of 78-inch sewer at a depth of 64 feet and a 57 million gallons per day (MGD) bypass.
- Multi-year Sanitary Sewer Rehabilitation which addressed recurring sanitary sewer overflows (SSOs), maintenance issues, and I&I in the sewer system.
- 54-Inch McAlpine Creek Sewer Rehabilitation is a current project to rehabilitate 22,900 feet of 54-inch sewer using ultraviolet cured-in-place pipe (UV-CIPP) lining. This will be the largest UV-CIPP project ever performed in the U.S.
