Water Accountability: Portable Monitoring Instruments Solve Flow Rate Mystery

摘要

The Glen Walter Sewage Collection System was built to service 1080 customers in 1989. At the time the population was 850 but by 1995 the sewage treatment plant had already reached capacity. Shawn Killoran took over the Operations Manger position in 1999 and, along with the Mayor and Council, he immediately had concerns about the excess flow. The Township started by video taping all of the lines in the collection system. The pipe work was found to be in good condition so significant infiltration was unlikely. Shawn realized he had to rethink the approach and find a way to leverage technology. He decided to monitor flow in high volume areas within the collection system. The Township selected Stingray Level-Velocity Loggers from Greyline Instruments because they are portable, work in partially filled pipes, and enable technicians to retrieve wastewater flow data without entering manholes.
