Our climate is changing and the demand for water resources is continually increasing, driving the need to enhance catchment resilience.
From fabricated solutions like fish counters to green engineering projects like leaky dams, our created assets are built smartly using recycled materials and low-carbon methods to reduce their environmental impact.
Our nature-based solutions and green asset creation programmes prioritise whole-catchment thinking, restoring water ecosystems to enhance climate change resilience, protect water quality, and secure sustainable access to water resources for people and wildlife.

A new fish counter & eel pass
A complex project in the South West of England, commissioned by the Environment Agency. The project involved the fabrication and installation of an access gantry, fish counter and eel pass, ensuring that fish and eels – an endangered species – are able to pass safely, promoting biodiversity and ensuring the species continues to spawn and thrive.
