Kooindah Waters is located one kilometre east of Wyong town centre on the New South Wales Central Coast. When complete it will comprise 252 one and two storey residential dwellings, an 18 hole championship golf course and various resort facilities such as a hotel complex with restaurant, bars and function facilities, tennis courts and swimming pools. The golf course was opened in April 2006 and houses are progressively being constructed. The site initially posed a host of challenges (described more fully in the case study for Conservation of Biodiversity) and it was decided early on that a Water Sensitive Urban Design (WSUD) approach, involving extensive water reuse and rain water harvesting, would be the most appropriate means of managing the water coming onto and off the development. Each house is fitted with a 4000L rainwater tank for water harvesting of 50% of the roof area to service toilets, laundries and irrigation. The resort is fitted with 80,000L of rainwater tanks to service irrigation, laundries and toilets. Similarly, the golf course maintenance facility is fitted with 40,000L of rainwater tanks to provide water for cleaning and washing down equipment each day after maintenance on the golf course. All overflow stormwater from all areas of the project including irrigation of the golf course ends up in the extensive bio retention swale network around the project. The swales, large vegetated verges designed to minimise impact on the storm water system, allow the water to infiltrate into the ground water system and replenish the upper 10m aquifer. This is then harvested by five bores located on the front nine holes of the golf course. Essentially 100% of all stormwater is utilised on the project. |
