A water audit will determine the amount of unaccounted-for water (UAW) and what actions are necessary to reduce losses.
Our Urban Mobile Lab provides assistance to public water supply utilities in conserving water and reducing utility system water loss.
The Southwest Florida Water Management District Urban Mobile Lab was established to provide assistance to public water supply utilities in conserving water and in documenting and reducing water loss. Lost water is water that for whatever reason “disappears” between the time it enters the utility’s distribution system at the withdrawal point (wells, surface water sources or interconnects with other utilities) and the time it leaves the distribution system through connections (water meters). In an ideal situation, the quantity of water which enters a distribution system through its withdrawal meters would equal the quantity of water exiting the system through service meters. Unfortunately, this is not the case. For example, water main flushing, though necessary to maintain water quality, results in water loss. “Real” water loss typically results from leakage and unauthorized use (theft), or a combination of these things. “Apparent” water loss typically results from faulty meters, poor accounting for unmetered uses, or a combination of these things. Much water loss can be prevented through loss control programs. The goal of the Southwest Florida Water Management District is that all public supply utilities will reduce water loss to 10 percent or lower.
The Urban Mobile Lab offers water loss and documentation assistance to any public water supply system. Services are provided to municipal or privately-owned utilities on a no-cost basis. Private property owners are not eligible. The Urban Mobile Lab provides systematic leak detection surveys or emergency leak location services and meter testing. Urban Mobile Lab services are scheduled workloads permit. For Urban Mobile Lab assistance, contact any Community Affairs Program Manager, or contact the Conservation Projects Section in the District’s Brooksville Headquarters.
A water audit is an accounting procedure that accurately determines the amount of water loss in a water distribution system. In addition to documenting the level of water loss, a water audit may indicate what actions are necessary to reduce loss. If testing indicates that withdrawal or service meters are not accurate, a meter replacement program may reduce water loss to an acceptable level. When poor accounting for unmetered uses such as water main flushing or fire fighting is identified as a contributing factor, the utility can take steps to track the quantity of water used for these purposes. If a water audit fails to indicate the reason for water loss, an effort to locate and repair system leaks may be the best solution.
