Lee Garnett from Council attended our November meeting to give members an update on these storage systems. The goals are to reduce demand for potable water use for irrigation, to create aquatic habitat, to increase amenity, improve waterway health by reducing the speed and intensity of flood waters, and to save money on water ills for community sporting clubs.
Water meters are on site to measure the volume of water collected. Council reports that the installations are currently providing 184 megalitres of water per year, and this will increase.
There are three types of stormwater harvesting stuctures :
1. Open water body
- Ekibin Park (formerly the site of Little Swamp Creek): This system is now fully operational and clubs are obtaining irrigation water from it.
- CB Mott Park: There were some teething problems with this installation but they have now been rectified.
2. Stormwater diversion from underground stormwater pipe into above-ground tanks
- Langlands Park: This device has a backflow prevention device to stop tidal flow from entering the freshwater storage tank.
- Sexton St Park: This will be completed behind the Wellers Hill Bowls Club.
3. Re-purposed concrete-lined channel
- Norman Park precinct: This system is still to be completed. It will be near Scotts Creek and Norman Park railway station.
Brisbane City Council's investment in these systems should have a positive impact on water quality in Norman Creek. You can read more about them on the Stormwater Harvesting page on the BCC website.
The image gallery shows the Stormwater Harvesting pond at Ekibin Park. The construction process was quite disruptive to the wildlife that formerly used Little Swamp Creek, but birds and animals are returning to the area and frogs have been heard there.
