FISH PASSAGE SOLUTIONS
Restoring river connectivity
Man-made structures such as weirs, culverts and sluices can disrupt natural river processes, restrict fish migration and degrade water quality. Over time, these impacts reduce biodiversity, ecological resilience and channel capacity.

Wherever possible, we prioritise the removal of artificial structures to restore natural river processes and reconnect habitats. When removal is not feasible, we design and install high-quality fish passage solutions that enable safe fish movement and improve ecological connectivity.
What we deliver:
- Weir and structure removal where appropriate
- Design and installation of fish passes
- Retrofitting solutions to existing structures
- Regulatory liaison and technical approvals
- Turn-key delivery from concept to installation

We work closely with regulators and stakeholders throughout, following the Environment Agency’s Fish Pass Manual to ensure the highest technical and environmental standards.
"The work has been well planned and delivered in an efficient and cost-effective way. Nature Based Solutions are a professional and knowledgeable organisation and are well respected in the delivery of environmental conservation work in the Tees Valley."
