Although the information audit has been the primary water conservation service offered to business customers for almost a decade, there is little documentation of how well this inducement approach actually works. This paper examines the actual implementation rate of recommended water efficiency measures identified in 151 technical audits in Southern California, Eastern Massachusetts and Southern Connecticut. The data from this survey cover two site audit services: the engineering study, designed for large or complicated water use usually found in industry or institutions like teaching hospitals; and the analyst survey, designed for small or simple water use usually found in commercial applications like restaurants or office buildings. Pequod performed all the analyst surveys and all but six of the engineering studies for Massachusetts Water Resources Authority (MWRA). Several factors are considered in determining the effectiveness of each of the surveys: actual water savings, life cycle savings, and marginal costs. For the analyst sample, the sum of water savings for all recommended measures was 19% of the water billed to those customers. The amount of water reported saved by the measures that were implemented was 36% of the recommended amount and 7% of the total used for the entire sample. For the study programs, the sum of water savings for all recommended measures was 26% of the water billed to those customers. The amount of water reported saved by the measures that were implemented was an amazing 59% of the recommended amount and 15% of the total used for the entire sample. The final results revealed: 40% implemented, saving 14%, for $.25/ccf.
