Shaping the future of water
Our expertise spans the treatment of polluted raw water using advanced technologies and we are at the forefront of global desalination.
From source to sea and back again
At Binnies, we are leading the response to one of the greatest challenges of our time: securing the world’s water future. Climate extremes, population growth, pollution and ageing infrastructure are testing every system we depend on.
That is why we bring together engineers, scientists and environmental specialists across disciplines to design resilient, low-carbon, and future-ready water systems while extending the life and performance of existing assets through smart asset management and proactive maintenance.
We have successfully delivered some of the world’s largest water supply projects, many of which have won awards, including single treatment plants with a capcity of up to 1.137 million m³/day. Our expertise spans the treatment of polluted raw water using advanced technologies to produce safe, high-quality drinking water, and we have been at the forefront of global desalination for more than half a century, delivering four municipal seawater plants in Singapore with a combined capacity of 729,000 m³/day.
A more sustainable water future
For over a century, we’ve evolved within the industry, from building reservoirs and treatment works to pioneering digital networks, water reuse, and nature-based design.
Our people combine deep technical expertise with creativity and care, helping clients protect resources, enhance ecosystems and ensure water security for generations to come.
From source to sea, and every drop in between, we are shaping a smarter, safer and more sustainable water future.

Water resources, dams and reservoirs
Water resources, dams and reservoirs
Securing water for generations to come
We safeguard water security through world-class reservoir, dam and storage design. From new strategic reservoirs to the modernisation of existing assets, we deliver complex, multi-billion-pound infrastructure programmes that manage floods, store water, and strengthen resilience for future generations. Backed by some of the most experienced reservoir panel engineers in the industry, we combine design excellence with digital innovation, asset management insight and sustainability to ensure lasting performance, safety, and reliability.
Treatment and desalination
Treatment and desalination
Cleaner, safer, smarter water
We deliver advanced treatment and desalination technologies that provide sustainable water supplies for communities and industries worldwide. From removing emerging contaminants such as PFAS, microplastics and nutrients to converting seawater into high-quality drinking water, our engineers lead every stage – from feasibility and pilot testing to full-scale delivery – integrating digital optimisation, energy efficiency and net zero performance.
Networks and conveyance
Networks and conveyance
The arteries of modern society
We design, manage and optimise water and wastewater conveyance systems – pipelines, tunnels, pumping stations and distribution networks – that keep communities supplied and environments protected. Using digital twins, AI-enabled analytics, and hydraulic modelling, we enhance reliability, reduce leakage and extend asset life while cutting carbon. Our expertise covers water conveyance, wastewater conveyance and network services, ensuring integrated, data-driven performance across the full asset life cycle.
Wastewater and reuse
Wastewater and reuse
Transforming wastewater into a resource
Our teams design and optimise treatment and reuse systems that recover energy, nutrients and clean water. Our expertise spans primary, secondary and tertiary treatment, nutrient removal, disinfection, sludge management and water recycling for industrial and non-potable use, delivering circular economy solutions that reduce abstraction and carbon footprint while safeguarding public health and the environment.
Bioresources and energy recovery
Bioresources and energy recovery
Turning byproducts into sustainable energy
We harness the energy potential of wastewater and biosolids through anaerobic digestion, combined heat and power, and nutrient recovery. Our bioresources specialists help utilities turn waste into clean energy, lowering emissions, reducing costs and supporting the transition to net zero operations.
Stormwater and nature-based solutions
Stormwater and nature-based solutions
Engineering for a changing climate
We integrate engineering and ecology to manage surface water, reduce flood risk, and enhance biodiversity. Our teams create sustainable drainage systems (SuDS), blue-green infrastructure, and catchment-wide nature-based solutions that protect communities, improve water quality, and deliver measurable environmental and social value.
Products and asset support
