Revitalising Ballarat’s Century-Old Sewer for a Sustainable Future

We are thrilled to be working with Central Highlands Water on Stage 2 of the Ballarat Sewer Build. This significant project marks a major upgrade to Ballarat’s wastewater network, replacing century-old infrastructure to meet the demands of the city’s rapidly expanding community and enhance wastewater management efficiency.

This phase of the project has included laying 2km of pipeline, integrating deep excavations, micro tunnelling, trenching, river crossings, and above-ground sections. A key focus has been on respecting Ballarat’s rich cultural heritage. We have taken special care near the Yarrowee River and historical landmarks to ensure our work honours and protects these significant sites. This includes a particular focus on the iconic bluestone structures and sites sacred to the Wadawurrung people.

Our commitment to environmentally conscious construction has led to several impactful initiatives. We have prioritised recycling trees and vegetation removed during construction, donating them to local organisations like the Ballarat East Men’s Shed and the Ballarat Wildlife Park. Additionally, we’ve engaged the community in a tree planting day to help rejuvenate the project area.

At Diona, enabling communities to thrive through the delivery of essential services is what motivates us. Working alongside Central Highlands Water and the Ballarat community is a privilege. This collaborative effort not only advances critical infrastructure but also strengthens the long-term well-being and sustainability of the region.
