Sydney Water’s Lower South Creek Treatment Program (LSCTP) has adopted several innovative process technologies. Delivering significant sustainability outcomes and helping pave the way to a more sustainable water services industry.
LSCTP achieved Sydney Water’s first ‘As Built’ rating of 'Excellent' with a score of 67, helping better gauge sustainability performance compared to other utilities and infrastructure projects.
LSCTP has introduced a regional biosolids hub, with the transfer of biosolids from Quakers Hill to St Marys treatment plan. This has created the scale and feasibility for a new anaerobic digestion facility with cogeneration at St Marys, to provide significant energy recovery from biogas, with the flexibility to implement co-digestion.
Three new process technologies have been installed including mechanical primary screens, aerated granulated sludge biological process for secondary treatment and thermal hydrolysis to enhance anaerobic digestion.
The project is estimated to achieve a 43% reduction in greenhouse gas emissions over the construction and operational life of the project. With on-site thermal energy recovery and electricity generation, the project is estimated to self-supply 67% of its electricity demand.
Additionally, all 10 possible innovation points were achieved for the implementation of Australian or NSW first technologies as well as exceeding expectations of ISCA’s Energy benchmark ratings.
UGL-WSP Adapt JV is Sydney Water's delivery partner for this program of work.
