Project Overview
The Cambridge Wastewater Treatment Plant upgrade is a major public works project in New Zealand, designed to support the region’s growing population and improve long term wastewater infrastructure for Cambridge and the wider Waipa district.
Delivered for Waipa District Council, Moddex was engaged by Spartan Construction on the $108.5 million new-build facility which includes multiple treatment and operational areas requiring safe, durable and compliant access throughout the site.
The Moddex Solution
Working with Spartan Construction, Moddex supplied and delivered nearly $1 million of pre-engineered access solutions throughout the Cambridge Wastewater Treatment Plant.
The scope included Tuffrail® TR20 and TR25 handrail and guardrail systems and custom Ezibilt™ platforms and stairs installed across multiple stages of the project.
Working from 3D models and using third party site scanning technology, Moddex’s in house design and engineered team developed Design Intents for handrails and custom Ezibilt™ solutions for a range of key operational areas including bioreactor, inlet works, contingency lagoon, septage receival facilities, chemical access area, biosolids processing facilities and the Waipa weighbridge.
Completed in April 2026, the project marks Moddex’s first WWTP project of this scale with Spartan Construction and has since led to the award of a second major wastewater infrastructure project.
