Water & Utilities

As an essential resource to sustain life, effective water capture, treatment and supply are of increasing environmental concern to Governments and utilities providers around the world.  They are seeking innovative solutions to effectively manage clean water and waste water assets.


Laing O’Rourke understands that the water industry is predominantly engineering-driven, with a high level of integrated civil, mechanical and electrical expertise required to deliver fit-for-purpose end products that meet the health and environmental needs of the communities they serve.  

In Australia we designed and constructed the country's first potable water recycling plant, and are a leading provider in the management and engineering of industrial water processing. 

In the UK we have delivered works as part of major framework agreements with clients including Yorkshire Water and Thames Water.

Laing O’Rourke’s leading in-house manufacturing, civil, mechanical and electrical expertise is crucial given these types of projects are very concrete and process engineering intensive. Our direct employment model is also a major benefit as it gives us greater control and dependability in delivering complex water projects on time and within budget. 

Using an innovative DfMA solution for the aeration and final settlement tanks, Laing O’Rourke delivered the project to upgrade facilities and build new capacity at one of Europe’s largest sewage treatment works on opposing banks of the River Thames at Beckton and Crossness. 

In the Australian coal seam gas market, Laing O’Rourke is constructing the Kenya Water Treatment Plant at Chinchilla in Queensland for client QGC, the second of three such plants for this client. These plants house the processing infrastructure needed to purify water released during the mining and capture process. 

Laing O’Rourke takes an integrated approach to deliver solutions to complex water management issues. Our capability encompasses expertise in pumping stations, processing plants, tunnelling, clean water, waste water and industrial water networks, and water main construction and maintenance to ensure the efficient operation of the water services for urban, agricultural and industrial purposes. 

We also offer broader gas and electricity utility network connection solutions from the installation of mains and service utility networks through to their continuous maintenance and eventual disconnection.

Sector facts

Using an innovative DfMA solution for the aeration and settlement tanks, Laing O’Rourke upgraded existing facilities and built new capacity at one of Europe’s largest sewage treatment works at Beckton and Crossness in London.

The Luggage Point Advanced Water Treatment plant in Brisbane, Australia produces 70 million litres of purified recycled water a day – a first for Australia – and thanks to advanced DfMA processes and offsite manufacture, was constructed in just 18 months to meet Government and community requirements in a time of extreme drought.
