This powerpoint presentation begins by providing a brief overview of on-site leaks thatrepresent a significant source of water loss amongsingle family residential accounts. A pilot study was initiated that had five objectives: quantify water savings attainable through leaknotifications; estimate consumptive portion of the water savings; quantify workload implications for Customer Services; quantify revenue implications based upon decreasedwater consumption; and, evaluate relative effectiveness of different notificationapproaches in prompting on-site leak repairs. Methodology included: from the trickle database, 400 customers were randomlyselected and sent notification letters; using a harvested sample, 119 of the original 400 respondentswere surveyed by telephone (+/- 7.5%); customer services conducted on-site measurements of tricklerates at those meters both immediately before and three weeksafter notifications were mailed; and, due to data collection challenges during the initial study, thenotification was repeated on a separate sample of 200+ metersfrom the "trickle" list, Meter Services collected AMR profiles,which were analyzed by Conservation (including blanks for QA). Results included: quantify the potential water savings achievablethrough leak notifications; quantify the consumptive portion of that potentialsavings; quantify workload implications for customerservices; quantify revenue implications based upondecreased water consumption; and, evaluate relative effectiveness of differentnotification approaches in prompting on-site leakrepairs. Costs and benefits are provided. Includes figures.
