This project entails a major upgrade to Bowral’s Wastewater Treatment Plant infrastructure that will ensure its utility for the next generation. The scope of work currently being carried out by Haslin includes:

• Inlet works with two mechanical band screens for fine screening and grit removal;
• Contingency for emergency storm or flooding conditions, in the form of a manual screened bypass to the existing storm detention pond, which later returns stored water to the treatment process;
• A new lift pump station to transfer influent to the bioreactors;
• Odour control measures
• Two new bioreactors and two secondary clarifiers;
• Tertiary filters consisting of four dual media filter cells and a new UV system;
• An aerobic digester;
• A new mechanical dewatering and sludge handling facility;
• Conversion of the existing catch/balance tank to an emergency storage tank;
• Upgraded reclaimed effluent system for onsite use.
