The City of Saskatoon, located in the plains of central Canada, completed in early 2007 an IWA/AWWA water audit utilizing in-house staff and the AWWA Water Audit Freeware software. In the summer of 2007, the City retained the services of Veritec Consulting Inc. to complete the implementation of pilot temporary district metered areas (DMA) in order to provide a detailed overview of the potential recoverable leakage within the system. The study also included the completion of a component analysis which coupled with the DMA implementation provided a "bottom-up" real loss assessment used to validate the "top-down" water audit. The results were also utilized to establish the economic leakage level (ELL) and a long term water loss reduction program. This paper provides details of the study approach and results with a particular focus on the component analysis and temporary DMA implementation for the "bottom-up" real loss calculation. Includes tables, figures.
