The Region of Peel, following the implementation of an IWA water balance exercise for the Caledon well systems, retained the serviced of Veritec, a Miya Group Company, to implement a water loss study across all systems. The project involved the design and implementation of DMAs and night flow analysis using the reservoir drop test methodology. In addition, sonic noise mapping and leak detection was completed on a total of 193 km of water mains.

The final analysis included the development of a component analysis of real losses using the BABE concept in order to validate and calibrate the top down water balance. The results were used to identify the short term economic leakage level and to develop on ongoing strategy to monitor and maintain leakage levels at their economic level.

The project was successfully implemented and DMA results showed little recoverable leakage and established appropriate level of background losses for pressure management evaluation. A total of six leaks were found and repaired with yearly savings in excess of 72 cubic meters per day.
