Introducing the Combined Real Loss Indicator (CRLI) - Alan Wyatt / Dave Pearson

The CRLI is a “new” indicator of unit real loss volume, which has multiple advantages, including the following. The CRLI

• is easy to calculate from a standard water loss audit,
• does not require pressure data (which is often hard to determine accurately)
• is accurate over a very wide range of connection densities
• is accurate for comparison of different utilities or over time in different utilities.
• facilitates performance assessment, target setting and real loss monitoring, in numerical or graphical formats.
• Has a very high technical rigor, when assessed using Frontier Analysis.

The CRLI concept has been applied in the Canada, England, Northern Ireland, Scotland, and the USA, on a pilot basis, for comprehensive evaluation. CRLI value has also been computed in Brazil, Chile, and Portugal, with plausible results.
