Location: Wanaka, NZ
Time: Oct 2024 – Mar 2025
As part of an infrastructure upgrade at the Wanaka Wastewater Treatment Plant, a comprehensive fabrication and supply project was initiated to enhance the facility’s operational efficiency and safety.
The existing water waste treatment plant was established in 1988. The plant was upgraded in 2000 and has now reached capacity and is due for an upgrade. In 2025, Taurus was selected to supply and fabricate key components for the plant’s new walkway and support structures. The scope of work included the fabrication of 6 walkway modules, 7 walkway pipe supports, handrails for the modules, and a stairway as well as the supply of FRP mini mesh grating and clip sets. Despite the project’s complex requirements and the need for precise fabrication to meet engineering specifications, Taurus successfully completed all fabrication work, with items hot dip galvanised for durability and corrosion resistance. The finished components were delivered to the Wanaka Wastewater Treatment Plant according to the agreed timeline.
Since the initial fabrication and supply of key components for the walkway and support structures, additional work ongoing, includes the outer manifolds, cross pipes, and a manifold central to improve the flow and control of the wastewater treatment process… These modifications have optimized the plant’s operational efficiency and accessibility for maintenance tasks. These upgrades, along with the original scope of work, have collectively contributed to the overall success of the project, reinforcing Taurus’s commitment to precision, durability, and seamless integration of complex systems.

This project, situated in central Wellington, was undertaken to address urgent challenges within the city’s wastewater system. Its main goals included seamlessly integrating a new pump station into the existing wastewater network, optimizing flow redirection, and preparing for a future connection to the Taranaki Street Rising Main. The driving force behind this initiative was to overcome the limitations of the current wastewater system, expand its capacity, accommodate future growth, and enhance the robustness of vital wastewater infrastructure.
The intricacies of the project were notable, with the pump station boasting a 10.88m external diameter and 8.66m internal diameter, situated approximately 8.5m below ground level.
Our scope of work was comprehensive and included:
Several challenges emerged during the project, and innovative solutions were required to overcome them.
The project achieved its objectives successfully and within the stipulated timeframe and budget. Client satisfaction was paramount, with our work meeting high standards and quality expectations. Effective communication and collaboration with BPC played a pivotal role in swiftly resolving potential issues. This project not only addressed critical wastewater network challenges but also showcased our ability to execute complex projects in confined urban settings with efficiency and professionalism.
By maintaining a pragmatic and straightforward approach throughout the project, we delivered results that met the client’s needs and upheld our commitment to excellence in engineering solutions.

Project Background
As part of the Council’s infrastructure improvements, the old Sydenham suction tank was replaced. Taurus was tasked with providing the pipework connecting the new tank to four existing well heads and a pump station. Additional structural installations such as a surrounding stairway and pipe supports were also part of the project.
Scope of Work
Challenges and Solutions
A sudden change in material and specifications was effectively managed by Taurus, who chose to use stainless steel pipes, allowing for a quick turnaround and minimal impact on the project timeline.
Taurus introduced a socketed pipe system for the underground sections, a first for all involved. Close communication with the supplier and the Council led to an alternative locking mechanism, negating the need for thrust blocks.
Some existing infrastructure was not aligned either parallel or perpendicular, which is fairly standard. This was effectively handled through on-site pipe fabrication, facilitated by our Hamilton crane, which enabled the easy manoeuvring of larger pipe sections.
Designing and installing the stairway was challenging due to its complex geometry and location. Through effective communication between our project office and the fabrication floor, the stairway was successfully installed.
Outcome
All components were fabricated and installed successfully. The experience has enriched Taurus’ project office and site team, equipping us with valuable skills for future projects.

Job number #101967
In early 2023, Taurus Engineering partnered with a company in Queensland, Australia, to deliver a pressure vessel for air purification in the chemical industry in Melbourne.
Build for demanding applications
The pressure vessel was built to the main specification of AS1210 Class 3 Pressure Vessel, with additional examination and pressure testing required to be done to Spec (4037-1999_R2016). All welding was done to ASME IX specs.
Constructed using grade 304 stainless steel with thicknesses between 5mm and 20mm, the vessel was made of plate, pipe, fasteners, rod, and machined flanges. These materials were chosen for their strength, malleability, and resistance to corrosive environments and applications.
Designed for corrosion challenges
The vessel was designed for a specific application in the chemical industry. However, due to its use, there were potential corrosive challenges that needed to be considered during the construction process.
Welding the pressure vessel presented multiple challenges, including Die Pen testing and 100% visual examination, as the vessel needed to meet the hazardous Class 3 specifications. Quality assurance checks needed to be thorough, and all material certificates were checked upon arrival. Multiple parties were involved in the welding process to ensure that no preparation was missed and that all quality assurance documents showed compliance with the AS1210 Class 3 specs.
The vessel had a capacity of 3.6 m3 and a maximum operating pressure of 0.58 bar. Its technical details made it unique and of particular interest to the chemical industry. The successful delivery of this pressure vessel demonstrated our expertise in meeting the specific needs of clients in the chemical industry and our commitment to meeting the highest quality standards.
