Acceptable Water Loss in Distribution System
Acceptable Water Loss in Distribution System
(OP)
Hi Everyone,
What would be an acceptable percentage of water loss within a distribution system?
The amount of water loss due to breaks and all bleeders are accounted for through either the Water Treatment Plant or the appropriate meters however, the percent of unaccounted for water still ranges between %15-%35. What could be the cause of this fluctuation? Is this amount of loss normal?
Thanks,
Goss

"The difference between water pumped or purchased and water that is metered or confidently estimated. Unaccounted for water should include, meter problems (i.e. master meter inaccuracies, domestic and non-domestic meter under-registration, etc.), unauthorized hydrant openings, unavoidable leakage, recoverable leakage, illegal connections, stand-pipe overflows and data processing errors.”

Many techniques are available to locate problem areas in water pipes: pressure tests, video camera, etc. Its prudent operations of a water company to know where problems areas are located in the system and factor them into the routine maintenance program. Remember, the original water network probably didn't take into account large water loses.
So, in case of a fire, or high demand day, the system (including the reservoir) may not be able to perform up to standards. 35% water loss may not be a lot if you have plenty of water, but it is a very big deal if the fire department suddenly looses water pressure.
