Water Distribution ACT Distribution map Canberra Water supply profile Water from the treatment plants is delivered by gravity fed bulk supply mains to service reservoirs. There are 44 service reservoirs in the Canberra water supply system which are either the excavated, concrete lined type, or the circular, above ground type in concrete or steel. All reservoirs are roofed and designed to blend in with the environment. Pump stations are used to pump water from lower to higher level service reservoirs. Each service reservoir stores around 912 million litres of water.
Consumers receive water through a network of reticulated pipes.
The reticulation system is divided into pressure zones with each zone served from one or more local service reservoirs. The quality of water from the catchment to consumers is evaluated through physical, chemical, and microbiological analyses of water samples from the dams, treatment plant, local reservoirs, and garden taps of Canberra residents. Other water quality problems may be due to problems in internal plumbing. If you notice blue water coming from any of your taps, your water pipes may be affected by copper corrosion .
