Sequana, a trusted consultancy specialising in water security and environmental management, has expanded its operations into the UK. With climate-resilient expertise forged in drought-prone Australia, Sequana brings decades of hands-on delivery experience to help address the UK’s growing water scarcity challenges.
“Sequana is not just another engineering consultant. We are the water security partner that utilities can rely on,” said Mike Walsh, Sequana Chair. “From landmark desalination projects in Victoria, Perth, Sydney and Adelaide, we bring global best practice, delivered locally. Our track record equips us to support the UK as it faces intensifying climate change, regulatory scrutiny and rising community expectations.”
The UK faces escalating pressures, with record drought, population growth and complex regulatory frameworks. These converging challenges emphasise the need for solutions that combine technical reliability with community confidence, exactly the expertise Sequana offers.
EXPORTING AUSTRALIA’S CLIMATE-RESILIENT MODEL
Sequana has guided utilities and governments through decades of drought and climate extremes. Its model of water security blends technical excellence, environmental responsibility and stakeholder trust. Projects such as the Victorian, Perth and Gold Coast desalination plants now secure water for millions, demonstrating Sequana’s ability to deliver resilient, community-backed solutions.
UK LEADERSHIP AND LOCAL DELIVERY 
Sequana’s UK business will be led by Darren Nabbs, an industry leader with more than 30 years of water, wastewater and desalination experience.
With a 100% success rate in guiding complex projects through approval gateways, Sequana understands how to anticipate requirements, avoid delays and build regulator confidence. Just as importantly, it brings proven capability in securing social licence, now a growing requirement in UK water planning.
“With the UK facing urgent water security challenges, we’re proud to bring the best of Australia and global practice to support utilities here,” Darren said.
“Our mission is simple: to deliver water security that is climate-resilient, has social license and is technically excellent.”
WORLD-CLASS TEAM AND APPROACH
Backed by a team of 200 specialists, including internationally recognised leaders, Sequana provides strategic oversight, governance, risk management and delivery expertise, not just technical design.
Acting as an extension of utility teams, its integrated advisory model ensures consistency from business case to operation, while maintaining community trust and regulatory confidence.
With its UK expansion, Sequana offers utilities and regulators a proven partner to deliver the technical, environmental and social outcomes needed for long-term water security.
