FEATURED APPLICATIONS

Water accountability portable monitoring for solving flow rate mystery

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.
