BIBIMULYA CONSTRUCTED WETLANDS WATER QUALITY STUDY
| Who: | Moreton Bay Regional Council |
| What: | Water Quality Study |
| When: | 2009 |
| Where: | Bibimulya Street Constructed Wetlands, Bribie Island |
| Why: | The Bibimulya Wetland is a highly modified constructed wetland that is located adjacent to urban development on Bibimulya Street, Bellara on Bribie Island. The system has been artificially constructed to manage urban drainage (flood mitigation/stormwater quantity management) and also to improve runoff water quality. The system consists of a series of interconnected wet ponds, drainage links and adjacent dry detention/flood storage areas. The purpose of the project was to investigate perceived water quality and odour issues associated with the wetland. |
| Outcomes: | A number of physical, chemical and biological measures of water quality as well as sediment chemistry were sampled and tested. The results of these tests indicated that hypoxia may occur on or near the bottom of the pond under certain environmental conditions and a number of circumstances were identified that may be contributing to the water quality and odour issues. Simple management measures that could improve the water quality of the wetlands were suggested, including:
