Campvale Culvert Renewal

Overview

Campvale Canal Renewal

Campvale Culvert Renewal

The Campvale Culvert was constructed in the 1960's to transfer stormwater from Campvale Canal into Grahamstown Dam. The culvert has been identified as approaching the end of its functional life.

Hunter Water is undertaking a project to decommission the existing culvert and construct new assets to maintain functionality. Two new pipelines will be constructed from Campvale Pump station to Grahamstown Dam which will replace the existing culvert.

The driver for this project is to ensure the ongoing safety of the dam. This project is not part of any potential future plan related to changing the volume of water pumped from Campvale Canal into Grahamstown Dam or addressing any concern about water quality in Campvale Canal.

For more information on Grahamstown Dam see here

Location

Construction work will be occurring on Grahamstown Road, 500 metres from the intersection of Richardson Road. Works will span from Campvale Pumping Station, across Grahamstown Road, to Grahamstown Dam.

Temporary closure of Grahamstown Road

Grahamstown Road will need to be closed for approximately 5 weeks from Tuesday 20 February 2018. New pipelines are being installed across Grahamstown Road, which is constructed upon the dam wall. To maintain the impermeable (watertight) seal of the dam wall during and after construction, open excavation, and therefore closure of Grahamstown Road, is required.

Hunter Water appreciates that the road closure will cause some disruption and we thank you for your patience.

Hunter Water has consulted with Port Stephens Council, NSW Roads & Maritime Services and Hunter Valley Buses regarding the road closure.

Information on temporary changes to Hunter Valley Buses route is available here.

Temporary closure of cycleway

The section of the cycleway and footpath along the dam wall will be closed at this location for approximately 6 weeks from Tuesday 20 February 2018.

 Key dates

  • January 2018 - work commences on site.
  • February 2019 - scheduled project completion date.
  • February 2018 to April 2018 - closure of Grahamstown Rd (for approximately 5 weeks).
  • February 2018 to June 2018 - closure of cycleway (for approximately 6 weeks).

*Dates may change due to weather events and other unforeseen circumstances.

 

Closure of Grahamstown Rd

Grahamstown Rd will be closed for five weeks from mid-late February 2018 until early-mid April 2018 (exact dates to be confirmed). Letters have been sent to nearby residents and we will update the website once dates are confirmed.

It is necessary to close the road due to the construction of dual pipelines across the road.

For traffic travelling north/east from the direction of Raymond Terrace:
Grahamstown Rd will be closed at the intersection with Richardson Rd.
Traffic will be diverted along Richardson Rd.

For traffic travelling south/west along Grahamstown Rd (Lisadel Rd) Grahamstown Rd will be closed to through traffic at the entrance to the Grahamstown Sailing and Aquatic Club. A traffic diversion will be in place at the intersection of Grahamstown Rd (Lisadel Rd) with Fairlands Rd Medowie. Local traffic will be able to access Lakeside Tce, Old Farm Rd, Kedahla Cl and Wade Cl.

Hunter Water has consulted with Port Stephens Council, NSW Roads & Maritime Service and Hunter Valley Buses as part of developing the road closure plan.

A map showing the road closure and traffic diversion points is available here.

Frequently Asked Questions

Why is this project necessary?

The Campvale Culvert, which transfers stormwater from Campvale Canal into Grahamstown Dam, was constructed in the 1960s. It is now approaching the end of its functional life. In order to ensure ongoing safety of the dam, the Campvale Culvert needs to be decommissioned. Two new pipelines are required to maintain ability to pump stormwater flows from Campvale Canal.

Is this project part of a wider plan to address community concerns about flooding in Campvale and water quality in Campvale Canal?

This project is not part of any potential future plan related to changing the volume of water transferred from Campvale Culvert into Grahamstown Dam, or concerns about water quality in Campvale Canal.

Will this project result in a flooding risk to my property if it rains?

This project will not impact flooding risks associated with stormwater from the Medowie Catchment. Hunter Water will maintain the ability to operate Campvale Pumping Station throughout construction of this project.

Why is it necessary to close Grahamstown Rd?

The pipelines that are being constructed to replace the existing culverts need to traverse the saddle embankment of the dam wall upon which Grahamstown road is constructed. The saddle embankment is made up of a clay core and concrete cut-off wall providing an impermeable seal. The interaction between the new pipelines and the dam wall requires diligent construction to ensure that the dam wall is not damaged and the impermeable seal is maintained. The level of detail required during construction can only be achieved through open excavation. Hunter Water appreciates that the road closure will cause some disruption and thank you for your patience during construction.

How will the Grahamstown Road closure impact on the local bus route?

Hunter Water has consulted with Hunter Valley Buses in regards to the road closure. The local bus route will be diverted during the road closure. Further information including details on the route diversion and timeframe will be provided by Hunter Valley Buses.
