Press Release

April 23, 2015

AECOM has secured three contracts through the Environment Agency’s Water and Environment Management (WEM) framework to undertake restoration works on rivers in the North of England.


The clients, the Environment Agency and charity Red Rose Forest, reflect a diverse and growing environmental-improvement sector spanning regulators through to charities. The objective of the work is to encourage the diversity of species in the rivers and their surrounding areas that have been affected by pollution and historic modifications such as channel realignment.

The rivers selected for conservation work are Worsley Brook in Manchester, the River Derwent in Yorkshire and the River Yarrow in Lancashire. These rivers have been identified as key habitats of species recorded as under threat within the UK Biodiversity Action Plan Priority List including otter, sea lamprey and bullhead fish on the Derwent. All of the watercourses and their associated floodplains have been heavily impacted by historic and contemporary human activity ranging from coal mining to dye works on the Yarrow to realignment and flow regime modification on the Worsley Brook.

AECOM’s water scientists developed restoration plans for the sites based on geomorphological principles to check if feature creation matched the processes operating at each site. Flood risk was assessed alongside the restoration options, and benefits were identified to flood-prone areas associated with the sites. Scheme drawings and method statements have been developed, and works have been delivered at the Worsley site. The result of the works will be watercourses that are better connected to their floodplains, improved in-channel and floodplain habitat quality and diversity, as well as reduced flood risk, with lowered silt loads on restored reaches designed to be self-sustaining, saving on maintenance costs. 

Omar Sholi, Senior Environmental Scientist at AECOM, commented: “These three projects form part of the Environment Agency’s long-term strategy to manage England’s river environment to a consistent standard in line with the Water Framework Directive. We are pleased to have the opportunity to support the Environment Agency and Red Rose Forest in their joint mission to protect and enhance our natural environment.”
