This powerpoint presentation begins by providing a brief overview of the relevance to North American utilities and
background to Trinidad and Tobago water loss
assessment. Methods for determining unmeasured
consumption are presented, along with
estimating unmeasured consumption,
validating system input meters,
assessing accuracy of large revenue meters,
validated water balance, and
water efficiency surveys. Conclusions indicate the following: it is possible to determine a reasonably accurate validated
water balance in a largely unmeasured system suffering
from intermittent supplies;
in systems with large numbers of sources, the confidence
in the system input volume can be high, even though
confidence in individual meters is not;
there are benefits in undertaking a water efficiency
survey as a part of an NRW assessment; and,
the high level of consumption from storage tank overflows
was an unexpected outcome of the water efficiency
survey. Includes tables.
