Our expertise

We have extensive expertise in strategic planning, delivery, operations and maintenance and have a proven track record working under various contracting models- designing and delivering water and wastewater asset reliability and renewals and capital infrastructure projects. We also offer a comprehensive suite of capabilities and technologies to renew or rehabilitate sewer, water and stormwater networks in regional and metropolitan areas. Our capability is broad and includes civil, structural, mechanical, electrical, design and process works and ensures the effective delivery of complex water infrastructure projects that help to build better communities. 

Pumping Stations and Pipelines

We collaborate with water utility clients and governmental organisations to deliver pumping stations that transfer water when gravity alone is not enough and when pressure needs to be increased. Our approach is agile, often integrating the design, construction and commissioning phases, prioritising efficiency and effectiveness. Each project is approached with a deep understanding of its unique challenges, ensuring we minimise risk and mitigate impacts on stakeholder, communities and the environment. 

Water and Wastewater Treatment Plants

In addition to pumping stations, we design and deliver complex water and wastewater treatment plant projects. We are adept at carrying out work under brownfield conditions and expertly navigate the complexities of integrating new systems within existing infrastructure to ensure minimal disruption and optimal efficiency. 

Pipeline Rehabilitation and Renewals

We provide end to end rehabilitation and replacement services across water, wastewater and stormwater utility assets. The broad range of solutions we offer, covering mains, pipes, pits, pumps and customer service lines, enables us to confidently investigate and recommend the optimal solution for each situation. 

Our solutions and technologies include conventional construction, lift and relay, removal of asbestos water mains, pureflow, pipe bursting, directional drilling, EX PVC fold-and-form pipe lining, CIPP pipe lining, structural patches, junction sealing, GRP jacking, dead-end lining, maintenance hole and pit rehabilitation, CIPM, civil repairs and vent shaft rehabilitation. 

Annually our pipeline renewals team completes approximately:

  • >20km of stormwater pipeline reticulation;
  • >100km of sewer network rehabilitation;
  • >15km of sewer main carrier rehabilitation;
  • 10km of spiral lining, with the longest line 180m at 600NB (3km of profile);
  • 3km of CIPP;
  • Replacement of 350 sewer ventilation stakes; and
  • 25-30km of water main upgrades.
