AWWA ACE99490

In the early to mid 1980s, the City of Jackson Water Department began experiencing a water loss of 14% to 17%. This was attributed to poor meter maintenance. The water loss is the difference between the pumpage and billed consumption plus adjusted bills, stuck meters, bulk water sales, bleeders and hydrant flushing. Because residential accounts are read and billed quarterly, it is necessary to use at least a six month period to establish actual water loss as adjustments must be made to billed consumption in overlapping billing periods. This paper discusses several strategies used to reduce water loss to more acceptable levels that include: improving maintenance on meters 3 inches and larger, an aggressive program to bring all large meters up to AWWA standards for accuracy and keep them there; replacing old 5/8 inch to 2 inch meters with new remote reading meters to improve accuracy throughout the distribution system; hiring a professional firm to check the river crossing; installing a new 30 inch propeller type meter on the influent line between the 7.5 milliion gallon ground storage reservoir and the pumping station; and, requesting notification of any unusual amount of water in either the storm or wastewater system.
