Scope

• Secondary Treatment Expansion

Augment capacity at Quakers Hill WRRF with a new secondary treatment process train to achieve a greater output by 2028. Treatment upgrade is expected to enable a flow split between existing plant and new assets delivered under this works.

• Advanced Water Treatment Plant (AWTP)

Produce the design and construct of a new AWTP, with a ADWF recirculation capability, which consist of ultrafiltration, reverse osmosis and a stabilisation standpipe that discharges out to breakfast creek. The Advanced Treatment Upgrade will be required to meet environmental discharge requirements.
