Council supplies metered drinking water to 15,700 properties (about 34,000 people) across the Western Bay District through a complex network of reticulation.
This network supplies three zones – Eastern, Central and Western – from which water is pumped from underground aquifers to individual properties.
Until the late 1990s Council’s water supply came from surface-fed sources (rivers and streams). These supplies sometimes failed to reach the national drinking water quality standards due to the water being affected by rainfall, rising waters, silts and turbidity. This resulted in Council being unable to supply clean potable water all the time. The overland nature of our infrastructure also put it at risk of damage in storms and floods.
We decided to convert from surface-fed to secure underground aquifers pumped by bores. This enabled us to achieve a more consistent quality of water and reliability of supply. It also allowed Council to increase its capacity to meet future demand and to improve reliability of supply in drought conditions.
This scheme employs the best technology to manage surface-fed supplies and consistently produce high quality drinking water.
