In today’s economy, water utilities must improve accountability by maintaining water system performance and extend the useful life of their distribution system. Water utilities must know what their water losses are in order to budget, plan, and correct deficiencies in their distribution systems. 

The first step that a water utility should take to determine their water losses both apparent and real is to test the accuracy of their master meters. Once a water utility knows what is being delivered into their distribution system, meter records from their customers should be totaled and compared. As stated in AWWA’s M6 manual, "Typically, the largest 10 percent of the meters measure 40 to 60 percent of a system’s consumption.” This difference is the water utility’s totalized apparent and real losses. Apparent losses can be determined by testing. Meters that are suspected to be inaccurate should be tested over a range of flows in accordance to AWWA standards. It is clear that this represents loss revenue to the water utility and justifies the next essential operation to be taken.

Leak Detection:
Using data obtained from meter testing and other meter records, a leak survey should be done to determine leakage (real losses) using state of the art leak listening devices and leak correlation equipment as needed. A leak detection survey will conserve a precious resource, lower production costs for the water utility and lower the utility’s real losses. Once the leaks have been located and prioritized, repairs can be scheduled after the next essential operation is done.

Valve Exercising:
How can leaks be repaired if the shutdown cannot be done? The importance of the proper operation of valves in a water utility’s distribution system for regular and emergency operation can’t be overstated. Are the valves accessible? Are the valves exercised on a regular basis? How would you like to have to tell a hospital, a school, or a senior residence center that they will be without water for an undetermined period because a valve shutdown had to be extended? 
When all valves in the distribution system have been properly exercised, the next essential operation can be performed.

Fire Hydrant Maintenance:
The importance of hydrant maintenance is obvious. LIVES are saved by a water utility providing the required fire protection when an emergency arises. The proper operation and maintenance of EVERY hydrant in a water utility’s system is ESSENTIAL. There are other significant benefits to be gained by regular hydrant maintenance. ISO ratings are weighted heavily towards the water system and its fire hydrant operability. Hydrant Maintenance is a pro-active project that creates a healthy water system. Hydrants that do not drain properly in cold weather climates can freeze and become inoperable.
