Reducing Water Loss Through Leak Detection Water Mains Nrw
Fast forward to 2012, and the Birmingham Water Works Board (BWWB) had the challenge of maintaining a critical pipeline that was constructed well before the board was even established in 1950.
In order to determine the baseline condition of nearly 8 miles of the RCP transmission main and proactively address Non-Revenue Water (NRW) loss, BWWB completed four inspections using SmartBall® technology, a free-flowing leak detection platform that operates while the pipeline remains in service.
The inspections using inline leak detection were very successful, locating 26 leaks of varying size with close location accuracy. Twenty of the leaks have since been verified and repaired by BWWB, while the remaining six leaks have been deferred due to their size or matched up with existing features.
In the August 2013 issue of Trenchless Technology, BWWB’s project was featured as an example of how utilities can manage their aging pipeline infrastructure through the use of advanced leak detection technology.
Highly accurate inline leak detection systems that can detect leaks and gas pockets in operational pipelines. These systems are used primarily on larger diameter water and wastewater transmission mains of all materials as well as oil & gas pipelines.
In early 2012, the Birmingham Water Works Board (BWWB) ran a successful leak detection program on 7.7 miles (12 km) of 42-inch (1050-mm) Reinforced Concrete Pipe (RCP). The inspected pipelines are part of BWW’s system that transports water from the Shades Mountain Filter Plant to different areas of the city.
