Project complexities, simplified by Alpha:
- Delivering an 800m+ live watercourse diversion under Environment Agency regulation, requiring staged approvals, controlled excavation methods and continuous monitoring to ensure compliance and hydraulic performance.
- Managing flood events, water levels and environmental risk during construction, including maintaining channel stability, preventing sediment mobilisation and protecting downstream water quality.
- Implementing robust environmental control measures, including sediment containment, pollution prevention and monitoring systems to ensure no environmental incidents.
- Coordinating multi-stakeholder interfaces, including regulators, landowners and statutory bodies, ensuring compliance with planning and environmental requirements.
- Managing public interface and access during construction, including installation of fencing, safe diversion routes and sensitive reinstatement of affected areas.
Scope of Works:
- Excavation and formation of an 800m+ diversion channel, realigning Salt Brook to improve hydraulic performance and site development capacity.
- Maintenance of live flow from an existing 1200mm outfall, ensuring uninterrupted water movement throughout construction.
- Channel grading and profiling, including formation of primary and secondary flow paths to support long-term hydraulic performance.
- Construction of a balancing pond, enhancing flood attenuation and managing peak flow conditions.
- Vegetation clearance, bank reprofiling and hydroseeding, stabilising the channel and preventing erosion.
- Installation of over 600m of palisade fencing, securing the site and protecting public interfaces.
- Reinstatement of access routes and public interface areas, ensuring safe and compliant integration with surrounding infrastructure.
