Capability Statement

We were a member of the Adelaide Aqua consortia responsible for designing, building, and commissioning the Adelaide Desalination Plant, the state's largest ever infrastructure project. The reverse osmosis plant is one of the most efficient in the world and can produce 100 GL of fresh water each year.

The project encompassed all construction disciplines including bulk earthworks, civil structures, marine, tunnelling, mechanical, electrical, and building works. Some 10,000 people were employed during construction.

On behalf of Unitywater, we're delivering critical new water and wastewater infrastructure to support growth on Queensland's Sunshine Coast. The new pipelines, pump stations, and storage reservoirs will support the new Aura and Harmony communities in the Caloundra region.

For the Aura development (which will grow to 50,000 residents by 2050), we're delivering a new wastewater network that includes over 12 km of 900 mm diameter pipeline and one pump station. We're also delivering a new water supply network for this community, that includes over 12 km of 800 mm diameter pipeline connecting the Ewen Maddock Dam to a new 12 ML water reservoir.

We used the optimum mix of tunnelling and trenched construction techniques to deliver the Barber Grove to Seaview Wastewater Treatment Plant Pipe Duplication Project for Wellington Water, causing the least impact possible.

The project involved the installation of a new 1.2 km long, 1 m diameter pressurised wastewater pipeline. It services 90% of the residents in Hutt Valley, improving water quality and catering to the region’s growth.

Through our local office, we've been working with Dunedin City Council to successfully deliver 'three waters' (wastewater, stormwater, and drinking water) upgrades.

As a member of the Council's works panel, we are one of a small number of organisations upgrading the city’s water and wastewater treatment plants through to 2031.

In Gisborne, on the east coast of New Zealand’s North Island, we upgraded a wastewater treatment plant, doubling its existing capacity while saving our customer 30% in construction costs.

The budget for the Gisborne Wastewater Treatment Plant Upgrade – Stages One & Two was tight, but we love a value-engineering challenge! Working with the Gisborne District Council, the team rescoped and redesigned the construction method, reducing the cost by 30% and reducing the carbon footprint of the job.

Our in-house mechanical team delivering these works has extensive experience in asset renewal, planned maintenance, and fabrication. They are using advanced techniques such as LiDAR scanning, 3D modeling, and the creation of digital shop drawings to reduce site work and save time compared with traditional methods.

Regularly recording site conditions using drone-captured photogrammetry data has also enabled better tracking and more accurate progress payment claims.

Co-financed by the Australian and Indonesian governments, we successfully delivered the Palembang Waste Water Treatment Plant Project to improve the health, quality of life, and the natural environment for 40,000 residents on the island of Sumatra.

The project represented a significant undertaking and the centrepiece of a wider program to improve Indonesia's overall sustainability and resilience of essential water assets.

We delivered this state-of-the-art wastewater treatment plant upgrade in Auckland, drawing on our learnings from past projects to value-engineer the design and fast-track the programme. We delivered the project on time and within budget, all while keeping the existing plant fully operational.

We were engaged (in joint venture) by Watercare to upgrade the Pukekohe Wastewater Treatment Plant to support population growth in Franklin, and improve the quality of the water discharged into the Waikato River.

In joint venture with Diona (the Water North JV) we're one of three major framework partners delivering SA Water’s multi-billion dollar capital delivery program. The 'Frameworks' model fosters collaboration and innovation in the planning and delivery of water projects across metro and regional South Australia.

During the first four years (2020 - 24) our team delivered approximately 150 projects, including the design and construction of:

Working across 10 different work sites, from private land to remote mountain terrain, we delivered a multi-staged upgrade of the water supply network on Rarotonga. Engaging a significant number of locals on the project, we've left a legacy of new skills and world-class water infrastruture for the Cook Islands.

As the largest infrastructure project ever undertaken in the Cook Islands, Te Mato Vai (meaning 'source of water') delivers fresh drinking water to all residential and commercial properties connected to the existing network. The project was an integral part of the Cook Islands National Sustainable Development Plan.

We're delivering Contract C1A, part of Singapore's Deep Tunnel Sewage System Phase 2 project.

Contract C1A, involves site establishment works, and all temporary and permanent above and below ground services and utilities for the new Tuas Water Reclamation Plant (TWRP). Located in the south west corner of the island, TWRP will receive both industrial and domestic wastewater.

Using an innovative caisson (sunk shaft) construction method, we designed and delivered the Warkworth Pump Station, part of Watercare's broader scheme to improve the wastewater network from Warkworth to Snells Beach.

We built the new 247 litre per second wet-well / dry-well pump station adjacent to an existing pump station in Lucy Moore Memorial Park, implementing construction strategies and approaches to protect the sensitive park and river environment.

As part of the Deerubbin WaterFutures Consortium, we designed and constructed of one of the largest water recycling plants in Australia. The St Marys Advanced Water Treatment Plant provides environmental flows to the Hawkesbury-Nepean River system and highly treated recycled water for industry and new homes in Sydney’s booming western suburbs.

The consortium included United Group Infrastructure, GE Water and Process Technologies, and ourselves.
