Project summary

Edit project overview to modify the project summary.

The Lower Lee Valley waterways are profoundly polluted. The problem of urban diffuse pollution is chronic and highly visible. It blights the potential of East London’s rivers, reducing them as an amenity for people, damaging them for wildlife and turning them into open sewers. These problems have existed for many years now, but increasing population density and climate change are seeing them intensify. What has been missing from efforts to tackle the problems is properly involving people. Awareness of the pollution is very low, evidenced by the proportionately small number of calls to the Environment Agency’s Pollution Hotline. East London’s communities are fundamental to any long lasting improvement in the Lower Lee Valley’s water quality. While strategic efforts will aim to address the problems truly sustainable solutions have to happen at the household and street level too. The issue of diffuse pollution must be addressed as a priority in improvement works to rivers, oth-erwise rivers in East London will still run with wastewater and road run-off.

Thames21 has secured funding from DEFRA for the Salmon’s Brook Healthy River Challenge – a project to reduce diffuse urban pollution in the Salmon’s Brook, a main tributary of the River Lea in Enfield. The project will see the creation of six community centred bio-retention and sustainable urban drainage systems (SuDS) along the Salmons Brook. These SuDS will intercept diffuse urban pollution, provide attenuation for flooding, and create new areas of biodiverse habitat and new amenities for local people.
