Dunkirk Wastewater Pump Station – A Milestone in Sustainable Infrastructure

At Maskell Productions Ltd., we are proud to have secured the contract for the Dunkirk Wastewater Pump Station in Auckland through our collaboration with Fulton Hogan. This significant project, part of a $51 million initiative by Watercare and Kāinga Ora, aims to prevent wastewater overflows into the Tāmaki Estuary while supporting residential growth in Panmure and the surrounding suburbs.

What We Delivered:

Our role involved the manufacturing and design of high-performance FRP (fiberglass-reinforced plastic) components that are essential to the pump station’s operation:

• Tanks: We designed and manufactured four 166,000-liter tanks, each 24 meters long.These large-volume tanks are designed to store wastewater and prevent overflows during heavy rainfall.
• Manholes: We produced four DN2000 manholes, each 5.4 meters deep, which are equipped with durable steel ladders for safe access. These manholes facilitate safe entry and control within the system.
• Wetwell: The DN3500 wetwell, measuring 8 meters deep, plays a vital role in handling high wastewater flow rates. It was pre-equipped with DN350 steel pipe rising mains, ensuring efficient management of wastewater flows. Penstock valves were pre-installed in both the manholes and wetwell to streamline on-site assembly.
• Valve Chamber: Our DN3500 valve chamber, with a depth of 3.7 meters, all necessary valves pre-installed, simplifying the installation process. Project Impact:

The Dunkirk Wastewater Pump Station is designed to manage flows of up to 225 liters per second, significantly reducing the risk of overflows into local waterways, including the Tāmaki River. The storage capacity of 700,000 liters in our tanks ensures the system can handle surges during heavy rainfall, providing reliable wastewater management for the surrounding community.

This project is a testament to the successful partnership with Fulton Hogan, highlighting our collective commitment to sustainability. By using FRP materials, we achieved a reduction of 1,400 tonnes of carbon dioxide emissions compared to traditional materials like concrete and steel. Furthermore, the fast installation process of our FRP products allowed for quicker and more efficient assembly, helping the project meet its deadlines. You can see the installation speed in action through the project video.

At Maskell Productions Ltd., we take pride in our ability to deliver solutions that combine high performance with environmental responsibility, thanks to our innovative designs and collaboration with industry leaders like Fulton Hogan.
