The projected water savings from the selected water use efficiency measures are difficult to estimate and measure. Some of the measures, such as conservation rates, notifying property owners of an unusually high water bills, and installing source and service meters have already been implemented.
Projecting water savings from new measures, including showing consumptive water use and conservation tips on the water bills is expected to be less than 3%. Savings this small can be difficult to measure, particularly when weather variations alone can have a much larger impact on demands.
Conducting a leak survey and repairing leaks could save 5% -10%.
Calibrating source meters and installing new service meters will not result in water savings but it could reduce distribution system leakage by 5% - 10%.
