Orange City Council has commenced construction of the Ploughmans Creek Stormwater Harvesting Scheme.
The Ploughmans Scheme will secure an additional water supply for Orange and will compliment the recently completed Blackmans Swamp Creek Stormwater Harvesting Scheme. It is anticipated the Ploughmans Scheme will add up to approximately 700 megalitres (around 17 per cent of current usage) to Suma Park Dam annually. The project is expected to be completed in September.
A Review of Environmental Factors was prepared last year and approved by Council in December.
A key component of the Ploughmans scheme is the construction of four wetlands located at Cargo Road, Escort Way, Sommerset Park and Burrendong Way. The constructed wetlands are multi-functional stormwater management systems that will improve stormwater quality, provide habitat diversity and create recreational areas.
The work across the four sites is expected to take up to four months. Following the earthworks, the sites will be revegetated with native plants specifically suited to constructed wetlands. The planting will be scheduled for the most appropriate weather conditions and time of year and is likely to be spring 2010.
The Ploughmans Creek Stormwater Harvesting Scheme consists of four wetlands, a stormwater retarding basin, two small V-notch weirs and associated pumps to pool and harvest stormwater flows and associated pipeline infrastructure to connect to the existing stormwater harvesting facility.
