HILLTOPS COUNCIL
YOUNG – WOMBAT ST RETICULATION MAINS

Renew Reticulation Mains and associated infrastructure

Hilltops Shire Council required a Design and Construct Potable pipeline to renew various water mains within the township of Young. Council has identified the need to replace the existing pipelines along Back Creek Rd, Wombat St, Berthong St, Brock St and William St as the existing infrastructure is showing signs of distress and deterioration and there are major leaking service outlets and continual mainline bursts in these mainlines.

Back Creek Rd and Wombat St

• Open trench Construction of approximately 3.3km of DN300 PVC Water main.
• Under boring of two major street roundabouts and a rail crossing
• 300mm DICL Underslung Bracketed Bridge crossing.
• Installation of 40 Fire Hydrant out valves along the mainline.
• Installation of 11 Isolation Gate Valves along Wombat St pipeline.
• Connection into the existing DN300 AC supply main at each end of Wombat St
• 25 branch line connections to pick up off existing AC main lines
• 210 existing meter connections to be transferred off existing mainline
• Manage Traffic Control and pedestrian movements per day along Wombat St
• Testing - Commissioning and Disinfection of new PVC Pipeline.

Berthong St

• Open trench Construction of approximately 1.7km of DN150 PVC Water main.
• Under boring of two major street roundabouts
• Installation of 25 Fire Hydrant out valves along the mainline.
• Installation of 8 Isolation Gate Valves along Berthong St pipeline.
• Connection into the existing DN150 AC supply main at each end of Berthong St
• 18 branch line connections to pick up off existing AC main lines
• 50 existing meter connections to be transferred off existing mainline
• Manage Traffic Control and pedestrian movements per day along Berthong St
• Testing - Commissioning and Disinfection of new PVC Pipeline.

Brock St

• Open trench Construction of approximately 830m of DN100 PVC Water main.
• Installation of 12 Fire Hydrant out valves along the mainline.
• Installation of 8 Isolation Gate Valves along Brock St pipeline.
• Connection into the existing DN100 AC supply main at each end of Brock St
• 75 existing meter connections to be transferred off existing mainline
• Manage Traffic Control and pedestrian movements per day along Brock St
• Testing - Commissioning and Disinfection of new PVC Pipeline.

William St

• Open trench Construction of approximately 870m of DN100 PVC Water main.
• Installation of 12 Fire Hydrant out valves along the mainline.
• Installation of 5 Isolation Gate Valves along William St pipeline.
• Connection into the existing DN100 AC supply main at each end of Brock St
• 2 branch line connections to pick up off existing AC main lines
• 70 existing meter connections to be transferred off existing mainline
• Manage Traffic Control and pedestrian movements per day along Brock St
• Testing - Commissioning and Disinfection of new PVC Pipeline

Highlights, Innovations and Key Risks

• Project finished on budget even with council variations as they arose
• No major disruption to town water supply through the project duration
• Daily traffic and pedestrian management along all Streets to eliminate delays
• No major underground service strikes for the duration of the project
• Pipe underslung on Bridge crossing
• Under boring of RMS Roads and major Roundabouts
• Under boring of Rail line crossing
• Branch roads to cross without causing traffic delays or business house disruption
• All metered services switched over without disruption to residential houses services
• Major disruptions to construction due to continual Wet Weather delays.
