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.

The NO-DES System is a unique and extremely effective method of removing corrosion and disinfection by-products from water mains. The NO-DES approach flushes water through its advanced filter system to clean the water, quickly and efficiently. It’s extremely portable and can be set up on site within minutes of arriving.

• It requires no shutdown of the water supply
• 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

• 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
