More than 430 miles of public sanitary sewer lines and 5,947 manholes need to be effectively maintained to help prevent sanitary sewer overflows.
Sanitary sewer systems collect and transport domestic, commercial, and industrial wastewater to treatment facilities. Creek bank failure due to heavy rainfall is a common cause of sanitary sewer overflows, as the large amount of pressure on the pipes can cause the line to break and overflow. Overflows have the capability to contaminate our waters, kill fish, cause serious water quality problems and economic loss, and result in property damage and public health impacts.
Over the last 10 years, Carrollton has only experienced 13 overflows, which is incredible. All of these were caused by heavy rains. To prevent overflows in instances of heavy rainfall, the City’s Public Works Department utilizes smart covers installed in three manholes on its transmission mains that send alerts if the flow begins to rise. This technology gives the department ample time to investigate the problem before an overflow occurs. They also conduct smoke testing on more than 100,000 linear feet of sewer lines each year to identify breaks, defects, and illegal connections to the wastewater collection system.
Additionally, the City performs sanitary sewer system rehabilitations in several neighborhood subdivisions each year with priority placed on its design standards.
