Pipe Scouring/Water Purge 

Air Scouring of water mains is an extremely effective ‘non-aggressive’ method of cleaning water mains. From 75mm diameter to 300mm diameter, with typical cleaning lengths ranging from 100 to 1000 metres. Factair, in conjunction with the Water Research Council pioneered the process in the UK. 
 
Air scouring works by using filtered ‘oil free’ compressed air, injected into the mains via a hydrant to propel a small volume of water at high velocity. Air and water are ejected together with any suspended solids from a hydrant at the end of the length being cleaned. This system has the effect of achieving water velocities high enough to carry loose deposits in the water stream.
