Esh Winning Sewage Pumping Station

Project Summary

Retroflo were engaged by Esh/Stantec to undertake the mechanical and electrical design at the initial I&D stage (now C&D) for a new three-pump sewage pumping station. The project included design, installation, and commissioning of the pumping station and a 60 kVA permanent standby generator with auto changeover facility. The installation enhances network resilience, ensuring a minimum of 48 hours of continuous operation during mains power outages, reducing the risk of flooding and pollution.

Scope of Works

Retroflo provided a full end-to-end service, including:

Mechanical and electrical design at I&D stage
60 kVA permanent standby generator with integral fuel tank (48 hours minimum operation)
Electrical design including cable calculations, SLDs, cable diagrams and loop diagrams
New GRP walk-in kiosk with intruder system
Re-purposed 3 pump MCC relocated from Johnson St
Three 15.0 kW VFDs
Three 13.5 kW submersible sewage pumps
250 mm ductile iron pipework and associated valves
Mechanical and electrical installation, commissioning and documentation
Associated civils installation
NICEIC 18th Edition inspection, testing and certification

Results

Strengthened network resilience with 48-hour backup capability
Reliable sewage pumping with integrated VFD-controlled pumps
Fully compliant M&E installation with NICEIC certification
Turnkey delivery including civils, commissioning, and documentation
