A better and more effective way of cleaning water pipes with virtually no water loss.
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.
Traditionally, water pipes have been flushed by opening fire hydrants and letting water discharge out into the street. The NO-DES system saves this water by attaching to two fire hydrants and creating a temporary above ground loop through which the water is circulated, cleaned and returned to the pipe. The NO-DES machine flushes the water between the hydrants at a velocity that intentionally stirs up the sediments, and then removes them in the purpose built NO-DES filters.

WHY CHOOSE NO-DES?
• It requires no shutdown of the water supply.
• It is a no disruption, efficient, effective way of cleaning water pipes,
• Minimal disturbance to customers supply (unlike conventional flushing), as NO-DES does NOT require the pipe to be de-pressurised or supply
to be turned off
• It is self-contained, with no water flushed down the street.
• It works using very high velocities.
• It filters and re-circulates the water inside the pipes (down to one-micron absolute – approx. 100 times smaller than the diameter of a human hair).
• It is a controlled flow providing for reduced damage – no water hammer or pipe / lining erosion.
• Conserves two vital natural resources — water and the energy it took to produce and pump it.
• Water quality is not compromised with the addition of Chlorine back into the supply if required.
