Originally built in 1965, the ageing Bird in Hand Wastewater Treatment plant needed an upgrade to support the growing population of the Adelaide Hills for the next 25 years. The existing plant consisted of 10 treatment lagoons. Its discharge was often foul-smelling and green in colour, which caused concern for residents.
SA Water approved the $60 million, three-year upgrade project that resulted in a 2.4 ML/d capacity, state-of-the-art, activated sludge treatment facility located in Woodside in the Adelaide Hills. This plant treats wastewater from several catchments including Lobethal, Woodside, Charleston and Inverbrackie.
Partnering for Success
Initially, we were subcontracted to GOLD Alliance for the concept development phase in an early contractor involvement arrangement. Later, SA Water engaged GOLD Alliance, a joint venture between Leed Engineering and Construction and Guidera O'Connor, to design, construct and commission the 12.5ML/d plant and we provided detailed design services.
Our early involvement in the project enabled us to deliver detailed designs quickly which saved significant time during the design process. We also resolved all site issues efficiently and without disrupting the project's schedule.
Delivered on time and on budget, the plant began treating water in September 2011 and was fully operationally by June 2012.
Overall, the community and environment have benefitted from the project. The new treatment plant delivers better quality water discharges local environment and health of the creek system. There is the opportunity for the future use of recycled water. The community can also now use water from the plant for local irrigation, reducing the strain on traditional potable-water resources.
