Water Utilities

Creating and maintaining water and wastewater infrastructure to help communities thrive

We have a proud history of supporting the Australian water sector that dates back 30 years.  Over that time, we have grown to become a leading infrastructure contractor working with water resources and urban water utilities across the east coast of Australia and New Zealand.  

Our unique skills and expertise include the construction of new assets, upgrades of existing treatment facilities and networks as well as tunnelling, sewer rehabilitation, and water main renewals. These capabilities help to make us an ideal program and project partner for utility clients seeking value for money outcomes for their customers. Our self-perform tunnelling and network renewal capabilities set us apart, enabling us to provide outstanding cost outcomes for our clients. 

Our teams work collaboratively with clients, are solution-focused, and look forward to opportunities for early project involvement to drive innovation, unlock value, and deliver win-win outcomes.

Our approach

We adopt a collaborative, outcomes focused approach to all projects and programs of work.  A significant part of our work in the water sector consists of long-term, collaborative delivery programs which include the West Region Delivery Team for Sydney Water, the Asset Renewal and Replacement Program for WaterNSW, Integrated Planning and Delivery for South East Water, Asset Upgrades and Renewal for Watercare (Auckland, New Zealand), Maroochydore Sewerage Treatment Plant Upgrade Program for Unity Water and the Safety Focus Performance for Melbourne Water.

Beyond program delivery, we also undertake small to large-scale green and brownfield projects working under all contract models common in Australia and New Zealand.  

Water and Wastewater Treatment

We collaborate with water utility providers to contribute to a sustainable water future. Our experience is extensive and includes the design and construction of both drinking water and wastewater treatment facilities ranging from upgrades of existing facilities to ensure optimal performance and efficiency to the delivery of new facilities to cater for growing demand.

Our team’s expertise includes process, civil, structural, electrical, mechanical and instrumentation to deliver reliable assets that service community and environmental needs. 

Our teams work closely with clients, designers and operators to carefully sequence and schedule works to minimise disruption and ensure compliance with operating license conditions. We create detailed plans, implement innovative solutions and maintain a strong commitment to safety and risk management, and sustainability across all projects.

We also build strong relationships with the treatment supply chain to leverage technology and resources to maximise value for money while complying with client standards and operators’ expectations associated with operability, reliability and maintainability.  Our goal is to deliver cost-effective water and wastewater treatment systems that will serve the community for years to come.

Water and Wastewater Network Assets

We also deliver new and refurbished linear infrastructure and asset renewals. Specialising in both civil and structural trenchless solutions, we prioritise measures to mitigate disruption to communities and the environment. Our expertise covers a wide range of services, from reticulation and major pipelines, to pumping stations and network renewals. Our comprehensive capability and approach allow us to meet the unique needs of each project, ensuring efficiency and effectiveness across all aspects of our work. 

Reticulation

Our reticulation services ensure the efficient distribution of water, wastewater, and stormwater through well-designed and maintained networks. We have the capability to construct pipelines using a variety of methods including open trench as well as micro-tunnelling and horizontal directional drilling. This versatility allows us to tailor our approach to the specific needs of each project, ensuring optimal performance and minimal disruption.

Major Pipelines and Tunnels

We have delivered major pipeline projects across Eastern Australia and New Zealand, ensuring the highest standards of safety and reliability, ensuring the seamless transport of water and wastewater over long distances. Like water reticulation, we can combine conventional methods with advanced techniques and strive to ensure all pipeline projects are delivered with care, delivering robust and reliable infrastructure that meets the needs of the community.

Pumping Stations

We collaborate with water utility providers 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, prioritizing efficiency and effectiveness. Each project is approached with a deep understanding of its unique challenges, ensuring we minimise risk and mitigate impacts on stakeholders, communities and the environment. 

Abergeldie Pipeline Renewals

We provide end-to-end pipeline renewal 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.
  • 25-30km of water main upgrades.
