Cromwell Water Treatment Plant Upgrade

Location: Cromwell, NZ

Time: July 2025 – Ongoing

Job #16256

 

Background

Taurus Engineering has been engaged by APEX to support the upgrade of the Cromwell Water Treatment Plant, a key facility providing essential services to the region. The upgrade focuses on modernising the plant’s infrastructure to improve efficiency, reliability, and long term performance. 

The existing water treatment plant required significant upgrades to meet increasing demand and maintain compliance with current standards. A critical part of this work involved replacing and upgrading the stainless-steel pipework, which plays a vital role in water distribution and treatment processes. 

Solution 

Taurus Engineering was responsible for the full scope of stainless-steel pipework fabrication and the installation of pipework in the water treatment plant. This included: 

  • Workshop fabrication and welding of all stainless-steel pipework in accordance with approved shop drawings. 
  • Weld inspection, pickling and passivation to ensure compliance with ASME IX standards and long-term durability. 
  • Protection and delivery to site, followed by site fabrication and welding. 
  • Installation, commissioning, and testing to integrate the new pipework seamlessly into the plant. 

Throughout the project, Taurus worked closely with APEX and project engineers to ensure all QA documentation, inspection requirements, and reporting standards were met. The next stage is already underway, with most of the main stainless-steel pipework scheduled for shipping at the start of October.
