Auckland water network suppliers work together

This year Auckland recognises World Water Day on a regional basis as the suppliers of bulk and retail water work together to get important conservation messages out to the public.

Auckland’s population is expected to double within the next two decades and this increase in density and urbanisation places pressures on water and wastewater infrastructure. With population growth and current demand of 300 litres per person per day (combined domestic and industrial use), Auckland may need a new water source within 24 years. Wise use of drinking water may move the timing of such a source and the significant costs associated with building and operating a new water supply and treatment plant.

Preliminary investigations indicate that if the Auckland region were to reduce water demand by at least 15 percent of 2004 levels by 2025, it would be possible to defer infrastructure expenditure of around $300 million on the next major water source.

Water efficiency improvements are already underway with Auckland’s water operators and regional demand this summer is 5.5 percent less than last year’s summer. It appears that water conservation messages are being heard and actioned by some residents and businesses, helping to save money and the environment. However, there are still many residents unaware of how they can use drinking water more wisely in and outside the home, yet it can be surprisingly easy to conserve.

Over the 17th and 18th of March an advertorial will appear in suburban newspapers outlining top tips on how to achieve drinking water savings at home, for both indoor and outdoor use. They include recommendations ranging from turning off the tap while brushing teeth and following water-wise gardening practices to installing a rain tank or barrel.

World Water Day on Sunday 22 March is an official international day sponsored by the United Nations.
