Cleaning and Disinfection of Water Systems
Mains Water Disinfection / Chlorination
This involves injecting pre mixed chlorine or a disinfectant into the mains water supply. The chemical is then drawn through to all outlets within the building. The chemical is then left within the system for 1 hour to kill any bacteria and cleanse the system. The system is then flushed with fresh mains water to all outlets within the building ensuring that no chemical is left within the system.
Cold Water Storage Tank Disinfection / Chlorination
The cold water supply to the storage tank is isolated and water within the tank is drained. The internal walls of the tank are then manually cleaned along with the removal of all residual water. The tank is then refilled with mains water and dosed with the appropriate amount of chemical. Water is then drawn through to all of the outlets and plant supplied by the tank.
