Kawana STP K150 Upgrade Project

KEY FEATURES

ACCIONA will be the process delivery contractor for the project with design, construction, and maintenance of the Kawana Sewage Treatment Plant upgrade.

• Current treatment capacity of 90,000 PE (population equivalent)

• Increase treatment capacity to 200,000 PE (150,000 PE specified)

• 24 months to design and construct

• Estimated in-service date is late 2018

BENEFITS

• The treatment process of Moving Bed Biofilm Reactor (MBBR) will be introduced which is designed in order for micro-organisms to grow which optimise capacity in quantity and quality of the water and is highly cost efficient.

• Due to the innovative nature of the MBBR process, the proposal submitted increased the treatment capacity from the specified 150,000 PE to 200,000 PE, without any significant CAPEX cost increase.

• This project will enhance the utilisation of by-products from wastewater through sustainably promoting co-digestion and generation of methane gas in order to generate electricity to offset the plants power requirements and thus reducing its carbon footprint.

CURRENT STATUS

ACCIONA has recently, in collaboration with Monadelphous, won the bid for the Kawana Sewage Treatment Plant upgrade project through Unitywater. The design and construction of the project will take an estimated 24 months which will be followed by a 12 months operational evaluation period. The project is currently underway.
