Once water has been treated at one of our 37 Water Treatment Plants it is distributed to our customers via an underground network of pipes.

Treated water is usually held in storage tanks and reservoirs to ensure adequate supply and pressure is available during peak-usage periods. Elevated water tanks and booster pumps are used to maintain water pressure throughout the reticulation systems.

Treated water is reticulated through a network of distribution pipes before being received by customers. At peak times water flows at an average speed of 1 metre per second through water mains, with it spending anywhere from a few minutes to a few days in the system before making it to your tap.

Pipeline cleanliness is maintained through an ongoing preventative maintenance program of flushing, air scouring and swabbing. Treated water storage tanks are also cleaned regularly.
