The Halifax Regional Water Commission was created in 1996 as a result of a Provincial amalgamation of three former water utilities in the Halifax metropolitan area. Each of the former water utilities had reported water losses quite differently. The new Halifax Regional Water Commission reviewed the water loss reporting information and found that significant inconsistencies were present in the reporting procedures. The utility undertook a comprehensive industry assessment of the available strategies for assessing and reducing system water losses. The International Water Association (IWA) Standard Water Balance and corresponding strategies were adopted by the Commission in 2000. The international approach to water loss reduction was applied in Halifax, and significant loss reduction results were achieved using international standards and strategies. The IWA approach quickly identified that standard terminology used in the utility, and throughout North America, is not the same as the terms applied internationally. The utility adopted many of the standard terminologies used internationally such as system input (production or system input feeds), active leak control, the adoption of "reported" and "unreported" leaks in its administrative process, district metered areas, and pressure management areas in describing the zones throughout the system. Several new concepts were adopted including the fixed and variable area discharge paths known as FAVAD, and component analysis of burst and background leakage estimates, or BABE, in calculating unavoidable losses from small undetectable background losses and unavoidable burst run times. The Infrastructure Leakage Index (ILI) was adopted as the leakage measurement and system condition indicator. The ILI is a ratio of the calculated annual unavoidable real loss (background losses and unavoidable losses) to the calculated annual real losses, derived from the standard water balance. The utility adopted this index for a more comprehensive assessment of the system leakage condition, described as a ratio of real losses over the lowest technical achievable loss level. The ILI can also be used as a utility comparison to assess the system condition and leakage performance on a national and international basis. The strength of this leakage performance measurement, and the comprehensiveness of the international approach to water loss assessment and strategies, were overriding factors in the Commission adopting the international approach to water loss assessment and management.
