Water Conservation

Hornsby Council has a number of initiatives to improve water efficiency within the Shire.

The most significant of these was being the first Australian council to achieve all five milestones in the Water Campaign by the International Council for Local Environmental initiatives (ICLEI), a worldwide association of local governments who have committed to improve global environmental sustainability

The award was presented to Hornsby Shire Council in 2007 after a 21 percent reduction in corporate water consumption and a 20 percent reduction in community water consumption.

Protecting drinkable water

Hornsby Shire Council has taken significant steps to reduce the amount of drinkable water that is wasted, with major success. The recent focus has been water conservation within Council buildings, through the installation of water saving devices such as dual flush toilets, low flow showerheads and tap aerators. These devices save around 35 megalitres each year – enough to fill 35 Olympic-sized swimming pools.

Council has also installed rainwater tanks and stormwater harvesting infrastructure at its community nursery and at a number of local playing fields. These include Berowra Oval, Greenway Park, Pennant Hills Park, Somerville Oval, Epping Oval, North Epping Oval and Roselea Park. Further stormwater harvesting and sewer mining projects are in the design or planning phase.

Partnerships with 10 local schools and three local lawn bowling clubs have also led to the installation of rainwater tanks. The tanks range from 2,500 and 10,000 litres at schools to 240,000 litres at bowling clubs. These are used to irrigate the gardens, bowling greens and school grounds.


How do we protect the water cycle?

The water cycle is the term for everything that happens to water between falling as rainfall and being evaporated again into the clouds. The Sustainable Total Water Cycle Management Strategy allows Hornsby Shire Council to manage the water cycle in a way that is ecologically sustainable.

Currently the main focus of the strategy is to maximise water re-use and conservation, which is achieved through a range of projects such as stormwater harvesting.
