The Warkworth and Snells Algies wastewater infrastructure is made up of five projects, being:
- the Snells Algies outfall
- the Snells Beach Wastewater Treatment Plant
- the Warkworth to Snells transfer pipeline
- the Warkworth Wastewater Pump Station, and
- the North West pipeline.
SNELLS ALGIES OUTFALL
Awarded to McConnell Dowell, the outfall pipeline involved construction 4.3 kilometres of a pressure/gravity main, 2 kilometres of a 1.2 metre diameter stell pipe, and 230 metres of outfall pipe. The Snells Algies wastewater pipe and outfall was completed in March 2021.
WARKWORTH WASTEWATER PUMP STATION
Awarded to McConnell Dowell, the project involved construction of a new pump station with 271 litres / second capacity. Construction began in September 2021 and was completed in June 2024. The station is located in Lucy Moore Memorial Park.
SNELLS BEACH WASTEWATER TREATMENT PLANT
The plant will process wastewater from the Warkworth and Snells-Algies communities, with Wastewater being pumped from Lucy Moore Memorial Park through a new five-kilometre pipe tunnel. The existing Warkworth Water Treatment Plant will be decommissioned. Construction began in early 2022 and is expected to be complete in 2024.
WARKWORTH TO SNELLS TRANSFER PIPELINE
A five-kilometre new pipeline from Lucy Moore Memorial Park to the new wastewater treatment plant. Construction began in 2022 and is expected to be complete in 2024.
WARKWORTH NORTHWEST GROWTH SERVICING PIPELINE
A proposed pipeline that will carry wastewater from the northern new developments to the Warkworth Wastewater Pump Station. Planning and design are currently underway.
