The $80m Pukekohe Wastewater Treatment Plant upgrade is a joint venture between McConnell Dowell and HEB Construction, requiring around 2500m of handrail.
With the goal of tripling capacity to meet the demands of population growth, the project comprises various stages, the most complex being the recently-completed reactor.
Pukekohe WWTP is a complex project with various teams of up to 120, working on different areas simultaneously. The scope for Moddex the reactor was for 200m 3-rail aluminium handrail system and another 1700m of handrail in HDG
Why was Moddex product selected?
The flexibility of Moddex’s pre-engineered systems enabled the work teams to work autonomously and install on-the-fly around varying site availability.
Assembly was able to take place on the ground, removing the risk of potential falls from the high platform.
Due to the highly-corrosive environment and high levels of H2S, Moddex supplied the proprietary Tuffrail® range in hot-dipped galvanised steel and aluminium.

Couldn’t have gone any other way for the speed we needed. Knowing how our builds are here, the component-based system gives us the option to build it when it suits the program.Bruce Williams
