We are pleased to announce the successful completion and dispatch of three 10m³ SPIROTAINER® units for the Porirua Wastewater Treatment Plant in New Zealand.
The units have now left the workshop and are en route to site, marking another key milestone in the delivery of reliable sludge handling solutions for municipal wastewater infrastructure across the region.
We’re excited to be exhibiting at Ozwater’26, Australia’s premier water exhibition and conference, taking place in Brisbane from 26–28 May 2026.
Join James Petrovski our Senior Sales Engineer, at the WIOA Bendigo Conference & Exhibition, where water industry professionals come together to share knowledge, technology, and best practice across the operations sector.
Operating costs in sludge storage and handling are driven by discharge reliability, minimal maintenance effort, and reduced operator involvement. Conventional sludge silos can struggle with sludge bridging, limited access for inspection, and material build‑up around the silo walls—often resulting in downtime, manual intervention, and increased operating costs.
The Cambridge Wastewater Treatment Plant in New Zealand is undergoing a significant upgrade to support a growing population and meet increasingly stringent environmental standards. SPIRAC has supplied the complete inlet works package together with a sliding frame sludge silo, and all equipment has now been delivered to site—looking excellent in position.
At SPIRAC, environmental responsibility informs every engineering decision.
As we approach the festive season, it’s the perfect time to pause and reflect on the year that has passed. 2025 has been a year of growth, innovation, and collaboration, and we couldn’t have done it without the continued support of our clients, partners, and dedicated team members.
SPIRAC is proud to be part of the ongoing upgrade at the Rouse Hill Wastewater Treatment Plant, delivering advanced sludge storage and handling solutions to support efficient operations.
