The Te Puke Wastewater Treatment Plant (WWTP) processes approximately 1600 cubic metres of wastewater per day. The plant consists of an extended aeration plant followed by tertiary treatment consisting of a brush filter, UV unit and a wetland. Treated effluent is discharged to the Waiari Stream.
This project is divided into two main sections:
a) Tertiary Filter installation
b) Recycled Water System installation
The tertiary filter installation looks to improve the tertiary treatment at the WWTP by installing a Hydrotech Disc Filter to reduce suspended solids in the discharge. The Disc Filter will be installed in a new concrete structure with associated inlet and outlet pipework. Solids captured by the filter will be backwashed by the filter to a new sludge pump station.
The existing brush clarifier will be kept operational to serve as a high flow bypass. The works will also provide preparation for the installation of future duplicate Disc Filters.
The recycled water system looks to reduce the potable water usage within the WWTP by reusing some of the treated effluent. The system comprises pumping, storage, measurement and chemical treatment of the effluent.
The Principal is seeking proposals from experienced civil works contractors who can:
• Reference a significant track record and relevant experience in similar projects
• Develop and provide a robust methodology and work programme.
• Provide all labour, plant, tools, equipment and materials necessary to complete the Contract Works, all in accordance with the specification and implied on the construction drawings.
• Meet Council’s project completion timeline.
