Sutton Forest Trunk Main

Upgrading a critical transfer main between Exeter and Moss Vale to strengthen regional water supply and support bushfire resilience.
Wingecarribee Shire Council
Sutton Forest, New South Wales

2.7km HDPE OD500 Trunk Main Installation

[Project Background]

Strengthening a Critical Water Transfer Connection

Wingecarribee Shire Council initiated the replacement of a 60-year-old cast iron trunk main that serves as a key transfer link between Exeter and Moss Vale. After decades of operation, the aging pipeline was showing signs of deterioration and required renewal to maintain reliable water supply across the network.

The upgrade introduced a larger capacity pipeline designed to improve system performance, reduce leakage risk through fewer joints, and ensure the network could provide reliable water supply, including critical flows required for bushfire response.
