Editorial: Precast wins in Warrnambool

Precast wins in Warrnambool 🏗️

National Precast Concrete Association Australia member Otway Precast played an important role in delivering the Warrnambool Bio Reactor, part of Wannon Water’s $85 million upgrade of the Warrnambool Sewage Treatment Plant in regional Victoria. 📍

The project incorporated more than 3,000 tonnes of precast concrete and approximately 350 tonnes of reinforcement. Otway Precast manufactured and installed the precast panels and associated structural elements for the 18 megalitre bio reactor structure. 💧

The project shows how precast concrete can support complex water infrastructure through durability, dimensional accuracy and consistent quality. Manufacturing the elements off site also helped simplify installation sequencing, reduce in situ concrete work and support greater construction efficiency. ⚙️

👏 A big thank you to Tim Reinen from Otway Precast for contributing the project content and sharing insights into its delivery.

📰 Thank you also to Ashley G. and the team at Inside Construction AU for bringing the editorial to publication in the August/September 2026 edition, pages 52–53.
