NO-DES is an innovative and effective way of cleaning water mains with virtually no loss of water. It delivers a cost effective solution to traditional methods of cleaning water mains. This technology increases customer confidence, reduces operational costs and conserves water and environmental discharge.
How it works
The NO-DES system creates a temporary above ground loop through which water is circulated at a high velocity in the reverse direction of normal flow, this then removes sediment and biofilms by passing the water through an extremely fine 24 chamber filtration system.
Water is continually circulated through the filters until the water is clean and turbidity targets are achieved, chlorine can also be added during this process if the client requires it.
During this process no water is discharged to the environment and customers remain in supply. Once the section is cleaned, the system can then be removed and located elsewhere.
