Our Work

Environment

River Restoration

Stonbury engages in a range of activities that protect the UK’s riverine habitats and restore streams and rivers to a more resilient, ecologically diverse status.
Environment

Large-Scale Weir Removal

Following a successful tender, Stonbury was contracted by the Environment Agency to complete the removal of a 70-metre-wide weir – the largest project of its kind in the country.
Environment

Water Feature Maintenance

Stonbury returns to a water feature it built two years ago as part of a long term maintenance programme.
Environment

Invasive Species Clearance

Stonbury was contacted by a local council regarding an on-line balancing pond that was built on the Moorgreen Stream, due to overgrowth of Typha latifolia (bulrush/reedmace) and the presence of the invasive non-native Hydrocotyle ranunculoides (floating pennywort) identified by the Environment Agency.
Environment

Harbour Desilting & Flood Gate Release

Stonbury was asked by the Environment Agency to propose and execute a solution to free a set of floodgates within a harbour on the bank of the tidal River Severn.
Environment

HYDROMETRIC STATION ASSET MAINTENANCE

Following the successful completion of routine maintenance works at over forty-five hydrometric stations, Stonbury has been awarded several contracts to manage and carry out routine quarterly maintenance at over one hundred gauging sites across Wales.
Environment

Stepped access Design, Fabrication & Installation

A client asked Stonbury to stabilise the banks at a monitoring station on the River Isbourne to improve the safety of the access to the river bank. The scope included the installation of a secure, gated, non-slip staircase with handrails, and cleaning and calibrating the river level gauge boards.
Environment

DAM AND WATERCOURSE REFURBISHMENT

A county council contracted Stonbury to carry out a package of repair works to dams and watercourse at various locations. The repairs were required due to deterioration of the masonry, erosion, tree root damage and water ingress.
Environment

Weed Screen Replacement

Following a successful tender, Stonbury was engaged by a client to design a trash screen that incorporated a manually operated vertical penstock screen.
Environment

IMPROVING WATER CONVEYANCE

Stonbury was contracted to complete works along a tributary of the River Avon in Worcestershire. The works were necessary to maximise conveyance and improve the positive impact of the flood storage area upstream.
Environment

RIVER CHANNEL WORKS

Working with an ecologist, Stonbury recently cleared 650 metres of dry channel, including the removal of obstructions to flow. Site won, green materials were then used to enhance the stream. Gloucester Wildlife Trust commissioned this work as part of the ERDF Wild Towns Project, which had been developed to create, connect and enhance green spaces for wildlife across Gloucestershire.
Environment

Bank Stabilisation

Stonbury was recently contracted to complete bank stabilisation works to a section of riverbank in the South of England. The scope of works also included the removal and disposal of Himalayan balsam and other native vegetation.
