The existing Rosewood STP with a capacity of 3,000 EP is located on the southern bank of the Western Creek approximately 1.5km upstream from the confluence with the Bremer River at Rosewood, QLD.
The old plant utilised the following equipment:
- Two intermittently decanted extended aeration tanks. WAS from these tanks was stored temporarily onsite, prior to being transported to Bundamba STP for dewatering
- Three open surface lagoons, one sub surface flow constructed wetland and an emergency lagoon for storage of raw sewage
- Chlorine contact tank; after disinfection effluent can be pumped to Rosewood Golf Course, stored on site and used as a supply of Class B water, or discharged via an outfall to Western Creek.
