Delivered on behalf of Cain Bio, in partnership with United Utilities and Cumberland County Council, this sensitive in-river restoration scheme stabilised a severely eroded section of the River Petteril. Initially scoped at 200m, works extended to approximately 250m during delivery.

The project combined robust civil engineering with nature-based solutions, incorporating over 6,000 tonnes of natural stone alongside bioengineering techniques to strengthen banks and enhance biodiversity.

Key Works Delivered

• Site enabling works including temporary fencing, ground protection, and compound setup.

• Selective vegetation clearance and harvesting of live willow for restoration works.

• Channel realignment through removal of sediment berms to reinstate historic river alignment.

• Installation of 140m of rock rip-rap along the west bank, with upstream and downstream tie-ins to existing infrastructure.

• 120m of downstream toe protection to prevent future undercutting.

• 250m of east bank reprofiling to restore natural channel form.

• Repairs to cracked utility pipe collars safeguarding critical assets.

• Integration of ecological enhancements including large woody material, live willow, coir rolls, and natural geotextiles.

• Full landscaping and reinstatement within Melbourne Park.

This project demonstrates a balanced approach to river engineering — delivering resilient bank protection while improving ecological value and protecting key infrastructure.
