Delivering emergency wastewater storage infrastructure and associated pipeline upgrades for Wingecarribee Shire Council.

Wingecarribee Shire Council

Bundanoon, New South Wales

Reservoir & Tank Installation

[Project Background]

Strengthening Wastewater Network Resilience

Wingecarribee Shire Council initiated upgrades to the SPS BU8 pump station to improve operational resilience and emergency storage capacity within the sewer network.

The project involved installing a new emergency storage tank alongside upgrades to the existing sewer rising main to improve reliability and system performance.

[Outcome / Key Features]

Emergency Storage Infrastructure Delivered for Sewer Network

Outcome

Installation of 200kL concrete emergency storage tank in accordance with AS 3735 standards
Construction of DN125 HDPE sewer rising main pipeline (approx. 1km)
Installation of vent stack and valve infrastructure associated with the storage system
Integration of new infrastructure with the existing pump station and treatment plant network

Key Features

Installation of aluminium access covers for tank maintenance and safety access
Construction of associated manholes and valve pits
Pipeline installation delivered using open trenching and HDD methodologies
