Saving water in Randwick

 image: "Water 4 Life logo" 

The Water 4 Life partnership aims to create awareness and understanding of Randwick Council's existing stormwater re-use projects that are implemented across various sites and facilities in Randwick Council.

The water saved through these stormwater recycling projects is around 100 million litres of water which is equivelant to 40 Olympic swimming pools each year.

The shortage and restrictions on water use around the Sydney metropolitan area is well known. Randwick Council's Sustaining Our City program is responding to the need for increased water conservation through new and ongoing projects which collect, conserve and reuse our precious water supplies across our City.

Stormwater re-use

The stormwater re-use system operates by harvesting water from nearby Gross Pollutant Traps (GPTs) and re-using the water for the purpose of irrigation, hence avoiding the use of our precious drinking water.

The amount of water saved through this harvesting system is around 100 million litres of water which is equivalent to 40 Olympic swimming pools each year! Four of our stormwater re-use projects are featured in the Water for Life campaign. They are:

  • Council's Community Nursery at Kingsford - A 140,000-litre underground stormwater re-use system has been constructed and is providing more than 60 per cent of the nursery's irrigation requirements

  • Clovelly beach, Clovelly - treatment and irrigation systems are now in place providing treated stormwater for irrigation and toilet flushing  including Clovelly Lifesaving Club and washing down paved areas

  • Pioneers Park, Malabar - - treatment and irrigation system recycling stormwater from the Gross Pollutant Trap in Cromwell Park saving around 40 million litres of townwater each year

Rainwater collecting in Randwick

  • We've installed rainwater storage tanks, which hold more than 90,000 litres of water, dual flush systems in buildings and water saving showerheads and taps at our beach amenities
  • More than 160,000 litres of rainwater tank storage systems have been installed across Council buildings including: 75,000 litres at the Works Depot at Maroubra; 20,000 litres at Council's Administration Building to help offset water used in the buildings air conditioning system; 20,000 at  the Des Renford Aquatic Centre, 20,000 litres at Bundock Reserve; 10,000 litres at Malabar Library; 10,000 litres at Perry Street Recycling Centre; and 14,000 litres at the Town Hall used to supplement car-washing and irrigation of garden areas.

Wastewater and backwash water re-use

  • The wastewater re-use system at the Council's Storey Street Depot is providing around 70 percent of the Depot's water requirements
  • a 240,000-litre water re-use system is installed at the Des Renford Leisure Centre in Maroubra, treating and reusing backwash water from each of the pools at the swimming centre.

In June 2009, Sydney Water replaced water restrictions with Water Wise Rules

The rules provide simple and sustainable actions, including:

� All hoses must now have a trigger nozzle.

� Hand held hoses, sprinklers and watering systems may be used only before 10 am and after 4 pm on any day - to avoid the heat of the day

� Use a bucket, watering can or a hose fitted with a trigger nozzle to wash vehicles

� Use water from your rainwater tank to water your garden, as long as it's not connected to or topped up with drinking water

� Hose paths, driveways, concrete or other paved surfaces for health, safety, emergency, construction or surface discoloration reasons are allowed. .

� Fire hoses may be used for fire fighting activities only.


Exclusions
Recycled water, bore water and water used for testing fire systems, fire fighting and related activities are exempt from the Water Wise Rules.

Water from rainwater tanks is also exempt if it is not topped up from Sydney Water's supply.
