Broomfield Park wetlands, Enfield - light case study

Where

The surface water drainage system was diverted to a newly constructed wetland within a well-used park to fit into the existing parkland setting.

The introduction of a wetland altered the way that surface water flows through the park, ultimately attenuating high flows.

The existing surface water sewer running through the park drained an urban area of approximately 40 hectares.

The wetland captures surface water from this area and removes pollutants before discharging to Pymmes Brook, a tributary of the Lower Lea, which is one of the most polluted catchments in the UK.
