Sydney Water has replaced the water restrictions with water wise rules. To get further information on these new water wise rules, tips on saving water, or to apply for an exemption, visit Sydney Water.
By taking the following easy steps, you can reduce the amount of water you use every day and save money.
To reduce water consumption at Council's assests Council has implemented a wide variety of water conservation methods ranging from the installation of low flow taps and dual flush toilets to larger scale projects such as the award winning water reuse project at the Gipps Road sporting complex, which uses stormwater diverted from a 91 hectare catchment area into a settlement pond and filtration units before being used to iirigate the Aussie Rules Oval.
Some other projects that stand out are the installation of rainwater tanks at nine sporting fields in the Holroyd area:
The stormwater captured in these tanks is being used to flush toilets and urinals in each fields amenities block.
Council has also adopted a Water Savings Action Plan (WSAP) to conserve water and implement more sustainable practices throughout the organisation. The Water Savings Action Plan provides an important framework to improve the efficiency of the use of water in Council operations, reducing both total water use and the cost to the community.
