YOUNG BACK CREEK RD TRUNK MAIN

3.7kms of 300mm PVC Trunk Mains and associated infrastructure

Hilltops Shire Council required a Design and Construct Potable pipeline upgrade for Young which obtains its water from Golden fields Water, project connection would start adjacent to the Terminal Storage Reservoir (TSR) on Back Creek Road. Council has identified the need to replace an existing DN225 Cl pipeline with a new pipeline of DN300 PVC pipeline from the TSR along Back Creek Road to a point just south of the intersection with Mathew Crescent, a distance of approximately 2.7km.The proposed pipeline begins on the eastern side of Back Creek Road opposite the TSR, runs along the eastern side of Back Creek Road until it transitions to the western side the road at a curve, and continues on the western side of Back Creek Road. The pipeline then turns west under Back Creek Rd and connects to an existing 450mm internal diameter AC pipeline. There are connections to existing rising mains, and 37 existing metered service lines, along the alignment. These pipelines are to be kept in service throughout the works and transferred to the proposed pipeline as part of the commissioning of the works.

Works Undertaken

• 2.7km of 300mm PVC Trunk Main along Back Creek Rd and reconnection.
• 11 required Isolation Valves, Air Valves and Scour Valves along the pipeline route
• 4 Trunk branch line connections to pick up existing branch lines
• 37 existing meter connections to be transferred of existing mainline
• 4 Road crossings along pipeline route
• Interconnect 300mm PVC main to existing 400mm AC including all isolating valves
• Manage Traffic Control and traffic movements per day along Back Creek Rd
• Testing – Commissioning and Disinfection of Pipeline

Highlights, Innovations and Key Risks

• Project finished on schedule and budget even with delays
• No major disruption to town water supply through the project duration
• RMS Road daily traffic management along roadside to eliminate traffic delays
• Manage Traffic Control with all interconnecting intersections along Back Creek Rd per day
• No underground service strikes for the duration of the project
• 4 branch roads to cross without causing traffic delays or residential disruption
