As Sydney go through the stormwater last week, the urban water collection is considered and the Kogarah Town Square is the best example in Sydney.
The Kogarah Town Square includes 220 residential apartments, 225 parking places, commercial retail place and a public library. The water management system in Kogarah Town Square was designed in a holistic water cycle management approach, The project aims to reduce the impact of stormwater through conservation and efficiency by reducing the reliance on mains water and managing stormwater quantity and quality through capture, reuse and treatment.

The three ways of Kogarah Town Square Project's urban water collection treatment and reuse are capturing stormwater from impervious areas, collecting rainwater from the roofs and reducing rainwater from the roofs and reducing the demand of potable water through water conservation.
In the impervious areas, stormwater goes through a gross pollutant trap that filters out the litter and large pollutants. The water is collected in a storage tank and pumped to irrigate landscape areas. It saves up to 2,130 kilolitres of potable water per year. In addition, the landscape area acts as a filter for the water, removing the excess nutrients and fine particles. The filtered water is collected and stored in a separate tank and used as a primary top up supply for the other tanks.
For the roofs, rainwater is collected in a storage tank under the public car park. The water goes through a screen filter and is pumped for toilet flushing, car washing and into the water feature in the Town Square.

About 85% of rainwater in the Kogarah Town Square is collected and treated. It is then used to flush toilets, wash cars, water gardens and to fill a park water feature. This has reduced demand for drinking water by 42% and saves over two million litres of drinking water a year.
The Kogarah Town Square was developed as a successful example of water collection and reuse.
