Grant Street Sewer Pump Station Upgrade

We are upgrading the existing sewer pump station in the reserve at the corner of Peelmans Lane and Grant Street.

Project snapshot

Town(s): Maddingley, 

Status: Under construction

Cost: $6.7m

Expected Completion Date: May 2021

What does this project involve?

We are upgrading the existing sewer pump station in the reserve at the corner of Grant Street and Peelmans Lane.

Construction involves the excavation and installation of two underground storage tanks, pumps and an above-ground electrical cabinet. The project will increase pump capacity from 37 litres per second to 100 litres per second, enabling additional sewage to be received and pumped to the Bacchus Marsh Recycled Water Plant in Parwan for treatment. 

Contractor Jaydo Construction Pty Ltd is carrying out the work on our behalf. Work hours are 7.30am–5.30pm Monday to Friday and 8am–1pm on Saturday (if required).

The pump station upgrade is part of a larger package of works, which includes the laying of a 7.8km sewer pipeline from Grant Street to the recycled water plant in Parwan and construction of an 800m water pipe from Griffith Street to East Maddingley Road.

Service relocation works

To accommodate the upgraded pump station, service relocation works were undertaken in November 2018 and again in June/July 2019. This involved excavation onsite to relocate gas, telecommunications, water and irrigated water services to a new location. Overhead power lines were relocated in March 2017.

Why is this project needed?

This investment is critical to ensuring Western Water can meet the increased demand for essential sewer and water services in Bacchus Marsh, particularly in fast-growing Maddingley.

What will be visible at the pump station site once the project is complete?

As the pump station will be installed underground, the only additional noticeable infrastructure will be an above ground electrical cabinet.

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.

Will my services be affected by the sewer main works?

No, we don’t anticipate any interruption to water supply or sewerage services.

What impacts can I expect once construction commences?


During works, vehicle access to Peelmans Lane from Grant Street will be maintained for most of the time. There may be occasions when access will be closed but this will only be for a short period and detours will be provided. The existing crushed rock pathway along the reserve will also be diverted during construction—in its place will be a temporary footpath along the edge of Peelmans Lane.


Some noise can also be expected from the operation of machinery but this will occur during daytime, thereby minimising disruption.


Fencing, barricades and trench covers may be used near the work site to ensure public safety.

What factors do we consider when planning a project?

Several factors influence 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
  • Southern Rural Water
