Wanganui Sewage Treatment Plant

The Wanganui wastewater treatment plant in New Zealand needed to be upgraded with a solution that was robust and could capture the odour produced from the plant. As a part of this upgrade, Treadwell worked closely with the mechanical contractor, builder and council to deliver an odour control cover solution using Treadwell’s EcoEX™ SureLine® HD system. In addition to containing corrosive gases, this project was designed to bear loads allowing safe access across the covers.

Project Challenges

Large spans between tank walls.
Designed to facilitate safe access for walking traffic across the panels in accordance with the roof loading requirements.
Exposure to highly corrosive hydrogen sulfide gas.
Required anti-slip surface that met P5 rating standards.

EcoEX™ SureLine® Heavy Duty FRP panels

Treadwell Solution

Treadwell’s high performance EcoEX™ SureLine® Heavy Duty FRP panels are manufactured from premium grade, corrosion-resistant fibreglass resins.
The panels for this project were designed and customized to meet live load requirements.
FRP is simply fabricated and modified on site. This means there is no need for any hot works permit.
Being lightweight and easy to install, FRP is very manageable during construction.
Given the nature of FRP, any system utilising it is virtually maintenance free, thus keeping maintenance costs as low as possible.
