Rapid residential development across South Australia’s northern corridor has increased demand for reliable sewer infrastructure capable of servicing multiple growing communities.
To support expansion across Munno Para, Angle Vale, and Salisbury, a high-capacity sewer pump station was required to transfer wastewater reliably to the Bolivar Wastewater Treatment Plant (WWTP) for screening and treatment.
Working in partnership with Fulton Hogan, Global Water Group delivered a modular, high-capacity sewer pump station and emergency storage system engineered to meet strict SA Water compliance requirements.
A fully packaged sewer pumping and emergency storage solution was supplied. It was designed to service multiple residential catchments feeding into the Bolivar WWTP. The system was engineered to support both current development demand and future network expansion, providing the following; long-term structural durability in buried sewer conditions, reliable hydraulic performance and compliance with SA Water infrastructure standards. Due to restricted site access and a limited construction footprint, a modular prefabricated solution was selected to process the large volume of wastewater, simplify installation and reduce on-site construction complexity.
The Roseworthy pump station presented a combination of technical, logistical, and compliance challenges typical of large-scale sewer infrastructure projects.
Such challenges were:
The project required a solution that balanced constructability, hydraulic performance, and long-term durability in a buried sewer environment.
To meet system requirements while simplifying installation, we delivered a fully engineered Volym dual pump concrete pump station, integrated with high-capacity emergency storage.
Volym Dual Pump Concrete Pump Station
Depth: 6.5 metres
Effective chamber diameter: 3.8 metres
Total wet well capacity: 20,000 litres
Duty configuration: Duty / standby
Performance: 93.1 L/s @ 42 m total system head
Pumps: Specialised 70 kW pumps designed for high-capacity sewer transfer
The pumping chamber was manufactured using HES 50MPa cement and calcareous aggregate, improving durability in aggressive sewer environments.
A HDPE liner was incorporated to provide additional protection against long-term corrosion and structural degradation in buried sewer applications.
Access & Maintenance Design
To improve operational safety and simplify ongoing maintenance, the pump station incorporates:
Linked access lids designed to improve safe access for maintenance crews and simplify pump servicing.
Emergency Storage Capacity
To provide resilience during peak flow events or abnormal operating conditions, the system includes:
4 × FRP emergency storage tanks
Capacity: 100,000 litres each
Diameter: 2200 mm
Length: 29 metres
These FRP tanks function as non-pressurised emergency storage, providing contingency capacity without being subjected to the operational loads experienced by the primary concrete pump station.
The Roseworthy Sewer Pump Station will provide reliable, high-capacity wastewater transfer supporting both existing communities and future residential growth across Adelaide’s northern corridor. Designed to service multiple suburbs, the system will efficiently convey wastewater to the Bolivar Wastewater Treatment Plant for screening and treatment, helping strengthen regional sewer infrastructure as demand continues to increase. With a modular, prefabricated design, the pump station also supports a more efficient installation process, reducing the complexity of construction within a constrained site area. To provide confidence from the outset, all key infrastructure components were tested to SA Water requirements prior to delivery, helping reduce risk during installation and commissioning while ensuring the system is ready to perform when it matters.
“Global Water Group were a valued partner in delivering sewer infrastructure for a large residential subdivision. They supplied a Volym pump station along with sewer holding tanks to support effective wastewater management.
