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