Batar Creek Road Sewer Pump Station

Scope

QMAX was engaged in 2021 by a development consultant to provide a sewer pump station for a Manufactured Home Estate (MHE) in Kendall, NSW. This development aimed to deliver affordable housing to the region through 200 additional residential lots. The project required connecting to Kendall’s existing sewer system, which necessitated running a sewer trunk main beneath regional road and rail infrastructure.

Upon assessment, it was determined that the existing pump station lacked sufficient capacity to accommodate the additional load from the new development. QMAX collaborated with both the consultant and Port Macquarie-Hastings Council (PMHC) to develop a comprehensive solution centered around a replacement sewer pump station.

The technical scope involved designing, constructing, installing & commissioning QMAX’s flagship 3.6-meter diameter pump station at a depth of 7.5 meters as a complete turnkey solution.. The system featured dual 22kW Flygt submersible sewer pumps and DN150 316 stainless steel SH10 pipework. All valves, flow meters, and associated equipment were carefully designed to meet PMHC standards. The pump station switchboard was strategically installed on an elevated platform to ensure protection from flooding, positioning it above the 1% Annual Exceedance Probability (AEP) level for the location.

Challenges

Several significant challenges were addressed throughout this project:

1. Infrastructure Constraints: Running the sewer trunk main beneath regional road and rail lines presented complex engineering and regulatory challenges, requiring careful planning and specialised construction techniques.
2. Capacity Limitations: The existing sewer infrastructure’s inability to handle additional load from 200 new lots necessitated a complete pump station replacement rather than a simple connection.
3. Technical Complexity: The installation of a 7.5-meter deep pump station with substantial diameter (3.6m) required specialised engineering expertise and construction methodologies.
4. Flood Risk Mitigation: Environmental considerations demanded that critical components, particularly the switchboard, be elevated above potential flood levels, adding design complexity.
5. Compliance Requirements: All aspects of the system needed to adhere strictly to PMHC standards, requiring detailed coordination and approval processes.
6. Future-Proofing: The solution had to address not just immediate needs but ensure capacity for the next 20+ years, requiring forward-thinking engineering and modeling of future demand scenarios.

Working in partnership with Eire Contractors, QMAX successfully overcame these challenges to deliver a high-quality asset that effectively addressed the sewerage needs of the new development. The completed infrastructure not only enabled the affordable housing project to proceed but also significantly upgraded the sewerage capacity for the broader Kendall area, ensuring adequate service for decades to come.
