Value in Every Drop, Stop Water Loss
Huge volumes of clean water are lost through leaks and overflows, and are not accounted for due to metering inaccuracies at consumers and illegal connections (theft). In many parts of the world this results in far more extraction than needed, and limited water resources are being over-exploited.
Non Revenue Water (NRW)
Water that has been produced and is “lost” before it reaches the customer. Losses can be real losses through leaks, sometimes also referred to as physical losses, or apparent losses for example through theft or metering inaccuracies
WHY LEAKS OCCUR?
The most problematic leakages are those that are not visible on the surface. The reason for the leakages can be the below mentioned reasons or combination of them.
– Water hammer and poor water pressure management
– Bad quality of equipment such as valves, joins, connections and pipes
– Deterioration of the distribution system
– Poor workmanship such as bad welding or wrong handling during laying of the pipes
– Corrosion of material due to acid soil condition
– Settings or movements in the soil
– Load from heavy traffic or construction work
– Frost settings in the soil
– Drying out of the soil
– Earthquake
– Illegal connections from water thieves
– Accident done by contractors during construction work
AVK offers various solutions for reduction of water loss in the water distribution network. So far, we have primarily described leakage monitoring and reduction of leakage by recommending high-quality and long lasting valves. But another solution – which AVK is also able to be part of – is pressure management.
