Wastewater Infrastructure Upgrades at Menangle Park and Menangle

NSW
Sydney Water
In progress

Our teams, as part of the West Region Delivery Team (WRDT), are delivering essential wastewater infrastructure to support ongoing growth in Menangle Park and Menangle. Located within the Greater Macarthur Priority Growth Area, these suburbs are experiencing rapid residential development, requiring new long-term assets to replace interim systems.

As part of this program, two new wastewater pump stations are being constructed alongside an upgrade to an existing pump station.

Scope of Works

Menangle Park – New Pump Station

The new pump station at Menangle Park provides vital wastewater capacity for expanding developments. The scope involves:

  • High-capacity submersible pumps with underground wet well and valve chambers.
  • Emergency storage and relief systems to maintain continuous service.
  • Instrumentation, control systems, and energy substation for reliable operation.
  • Site infrastructure, including hardstand, driveways, lighting, fencing, and stormwater drainage.

Menangle – New Pump Station

The new Menangle pump station will service new developments and replace an existing interim facility. The scope involves:

  • High-capacity submersible pumps with underground wet well and valve chambers.
  • Emergency storage, surge vessels, and a permanent diesel generator for resilience.
  • Instrumentation, control systems, chemical dosing and energy substation.
  • Site infrastructure, including hardstand, driveways, lighting, fencing, and stormwater drainage.

Menangle Park – Existing Pump Station Upgrade

The existing Menangle Park pump station has been upgraded to increase capacity and modernise electrical and control systems. The scope involves:

  • Upgrade of high-capacity pumps.
  • Electrical system and switchboard modernisation.
  • Odour control improvements and underground services.
  • Stormwater drainage upgrades.

Coordinating multiple sites

The project spans three separate sites, each at different stages of development. Coordinating access, design and construction across these geographically dispersed sites requires careful planning and integration with surrounding developer works.

Maintaining service during upgrades

The new pump stations replace interim facilities while maintaining continuous wastewater service through staged connections and careful interface management. Integrating these assets into a rapidly evolving network requires close coordination with Sydney Water, developers and utility providers.

Complex electrical and mechanical works

Significant electrical, mechanical and pumping upgrades, combined with construction within active urban release areas, demand precise planning, specialist equipment and ongoing stakeholder collaboration to ensure safe and efficient delivery.
