Western Water is building a new sewer pipe from Grant Street to the Bacchus Marsh Recycled Water Plant, and constructing a new water pipe from Griffith Street to East Maddingley Road.
Status: Under construction
Expected Completion Date: May 2021
Construction update—October 2020
Western Water is aiming to minimise disruption during construction. As part of current works along Parwan Road, between East Maddingley Road and South Maddingley Road, priority is being given to school buses accessing nearby Bacchus Marsh Grammar in the morning and afternoon peak. Parwan Road will have a single lane in operation but not always—there will be times when both lanes will be open to traffic. This work is anticipated to be completed by early December.
From early November, a section of pipe will be laid along Parwan South Road, starting at the Parwan South Rd /Parwan-Exford Rd intersection and continuing through to the Bacchus Marsh Recycled Water Plant. During this time, access to Parwan South Road from Parwan-Exford Road will be restricted during weekdays—although access will still be available from Nerowie Road to about Aerodrome Road. This section of work is expected to be completed by mid-February 2021.
What does this project involve?
- Construction of a 7.8km sewer rising main, starting at the sewer pump station on Peelmans Lane and traversing Grant Street, Parwan Road, Geelong-Bacchus Marsh Road, Parwan-Exford Road and Parwan South Road before connecting to our recycled water plant at Parwan. It includes the trenchless crossing of the Bacchus Marsh train station.
- Construction of a new 800m water pipe from Griffith Street to East Maddingley Road. Water pipe will be laid alongside sewer pipe in the same trench along part of the construction alignment, mainly along Parwan Road between South Maddingley and East Maddingley roads.
Contractor Jaydo Construction Pty Ltd is carrying out the work on our behalf. Work hours will be 7.30am–5.30pm Monday to Friday and 8am–1pm on Saturday (if required).
Why is this project needed?
Bacchus Marsh’s population is growing fast, particularly in Maddingley. As such, the existing networks need to be upgraded to ensure Western Water can meet the increased demand for essential sewer and water services.
Will my driveway be affected by the sewer main works?
During construction, contractor Jaydo may need to work across some driveways; however, we’ll notify residents in advance if this is required, and we’ll work with residents to maintain access. Once works are complete, the driveway and roadside will be returned to its original condition. Water may also need to be turned off briefly but again we will notify residents in advance of when this will occur.
Why is a water pipe being constructed at the same time as the sewer main?
A new water pipe is needed to boost water pressure downstream to businesses in Parwan, an area that is projected to have economic growth in coming years.
Part of the construction alignment—at the southern end of Grant Street and a section of Parwan Road between South Maddingley and East Maddingley roads—will include the laying of both water and sewer pipes in the same trench. This means we can consolidate construction and reduce impacts to residents along Parwan Road.
What impacts can I expect during construction?
Western Water will keep construction impacts to a minimum; however, the following is likely to occur:
We anticipate there will be some impacts to road users, as construction will take place along the Grant Street service road, Maddingley Recreation Reserve car park and Parwan Road rail crossing. Traffic management will be in place during this time.
Some noise can also be expected from the operation of machinery but this will occur during the daytime, thereby minimising any disruption.
There will be excavation work near the roadside. Fencing, barricades and trench covers may be used near the work site to ensure public safety.
Works during the coronavirus
In response to the coronavirus (COVID-19) outbreak, workers on outdoor sites will ensure they are at least 1.5m apart from each other at all times. This is in line with social distancing guidelines adopted by the construction industry and consistent with advice provided to the community. As an essential service, this work must continue, and our priority is to provide every customer with safe and reliable water and sewerage services.
What do we consider when planning a project?
There are several factors that inform our project planning. These include environmental and geotechnical impacts, cultural heritage, specialist investigations (such as a biodiversity assessment), population forecasts, location of other underground services (e.g. electricity, phone/internet, gas lines) and accessibility.
Consideration of future infrastructure in the area, such as major roads and drainage scheme infrastructure is pivotal to our planning along with advice from key stakeholders such as Moorabool Shire Council, Department of Environment, Land, Water and Planning, Landcare, Melbourne Water, Vicroads, VicTrack, and Southern Rural Water
