Improving water efficency
Decentralised water is about improving the way water is being used for buildings and operations, sourcing water locally for non-drinking purposes and the quality of our waterways.
Rethinking water use
Our current water strategy is to build large dams, hope for rain, treat all water to drinking quality, pump it all the way to the City and then only drink 2% of it. Even if we add the amounts used for showering and cooking, drinking water requirements equal no more than half of our total water consumption.
The other half is used for things like flushing toilets, air conditioning and watering parks and gardens – these jobs don’t need such high quality water. Also, more than half the water infrastructure in the local area is more than 70 years old.
The current water network is inefficient, unsustainable and highly sensitive to climate change. It’s time to rethink how we deliver Sydney’s drinking and non-drinking water supplies.
The City of Sydney has worked closely with a huge range of industry partners including Sydney Water, to come up with a solid master plan that will ensure the local area’s water needs are met sustainably. We are thinking locally, rather than relying on large-scale remote solutions.
Localised management of water, wastewater and stormwater is a major part of the plan. The best solution for Sydney is based on water efficiency, recycled water options, a reduction in stormwater pollution and cost. The plan, available for download below, details how we aim to bring together these solutions, where they should be located and how they will perform.
