Eridge Park Road Water Transfer Pump Station

Project Overview

QMAX Pumping Systems delivered the Eridge Park Transfer Water Pump Station for Wingecarribee Shire Council, providing a reliable above-ground solution to strengthen water security for the Southern Highlands. The project involved the complete design, construction, installation and commissioning of a high-capacity water transfer facility connecting the Bowral–Moss Vale trunk main to the Moss Vale reservoir.

Scope

QMAX was engaged to deliver the full project lifecycle, from concept design through to commissioning. While QMAX typically specialises in underground sewer and stormwater pump stations, this project required a tailored above‑ground solution.

The pump station was engineered to transfer water from the trunk main between Bowral and Moss Vale and fill the Moss Vale water reservoir to 98% capacity, ensuring improved reliability and resilience for the region’s supply network. QMAX developed comprehensive design documentation covering the station layout, operations, controls, and mechanical configuration.

System Overview – The integrated pumping solution included:

• Two Grundfos end-suction pumps to achieve 145 L/s at 45 m head
• Purpose-built precast concrete pump room with 50-year design life
• Track-mounted crane system for safe, long-term maintenance access

QMAX also delivered the full electrical and control system, including a frame‑mounted pump controller with pressure monitoring, flow display, and automatic mains‑to‑generator changeover capability. The system was fully integrated with Wingecarribee Shire Council’s SCADA network, enabling remote monitoring and operational oversight. Power supply works included ASP3 design, installation of a 500kVA transformer, and mains connection to the pump room.

On‑site works included:

• Construction of a reinforced concrete slab and access driveway
• Installation of all mechanical and electrical equipment
• Connection to the existing trunk water main – requiring excavation of Eridge Park Road to complete the tie‑in.
• Full system programming and commissioning, along with the operation and maintenance documentation in client handover.

Challenges

The Eridge Park project had several challenges that required the team to adapt, given the above‑ground nature of the pump room; a unique configuration for QMAX Pumping Systems. While we have delivered similar structures before, the shift from underground wet‑well environments to a fully enclosed building demanded a different approach to spatial planning, equipment layout, and long‑term maintainability.

Key challenges included:

• Constrained site location and access, located approximately 10 m from Eridge Park Road
• Managing traffic and public safety during road excavation and trunk main tie-in
• Integrating large mechanical equipment and a track-mounted crane within the pump room
• Coordinating delivery and installation of heavy precast and mechanical components

Despite these challenges, QMAX successfully delivered this project with our disciplined planning, strong communication, and a collaborative approach with Wingecarribee Shire Council. The completed pump station demonstrates QMAX’s capability to deliver complex water infrastructure solutions with the same precision and reliability that define our underground systems, while supporting improved water security for the Moss Vale community.
