Exotec offers two different methods for water main cleaning: Veloce Plus and Veloce.

------------------------------------------------------------------------------------------------------------

1. Veloce Plus: Cleaning and passivation of cast and ductile iron water mains in order to restore flow

and pressure and prevent water quality deterioration. The objective of the passivation is to 'harden' the pipe wall and accelerate the natural passivation process, thus stopping the undesirable 'leaching' of the pipe following the removal of encrusted sediments.

ENV EXOTEC PASS passivation solution is certified NSF/ANSI standard 60.

Benefits of Veloce Plus include:                                                

                                

  • Up to 80 % savings compared to other non-structural rehab methods
  • No need for temporary water supply
  • Up to 200 meters cleaned per day
  • Water service is restored to customers on the same day of work
  • No need to close service lines
  • One (1) access pit for up to 300 meters of water main
  • Proprietary NSF passivation process prevents discoloured water
  • Immediate improvement of flow - pressure - water quality
  • Delay replacement costs for many, many years....

 2. Veloce: Air scouring to flush-out the non solidified deposits and improve water quality.

See a schematic of the Veloce process.

Benefits of Veloce include:

  • No excavation
  • No need for temporary water supply
  • Up to 1 km of water main cleaned per day
  • Cleans the water main in BOTH flow directions
  • Scouring velocities of about 5 meters / sec.
  • Water service is restored to customers immediately after the cleaning
  • Optional: Soaking of NSF certified surfactant to help dislodge sediments
