SuDS: Policy Position Statement

Floods, drought, nature decline and polluted water running off our land are growing problems in the face of climate change, development and land use change.

Part of the solution to all these challenges, particularly (though not exclusively) in the urban context are Sustainable Drainage Systems (SuDS). SuDS mimic natural processes and reduce flooding – particularly surface water flooding associated with sudden downpours – by managing rainfall close to its source and wherever possible at, or near the surface. By building in rain gardens, permeable paving, green roofs, swales, soakaways or ponds, SuDS slow, store and treat water that could cause damage.

Alongside flooding, we also face increasing pressures from road runoff pollution and sewage pollution of rivers from storm overflows that are exacerbated by climate change and development. Well-delivered Sustainable Drainage Systems (SuDS) can help respond to these challenges, build climate resilience, enhance urban beauty, improve air quality, human health and wellbeing, and contribute to nature recovery.

CIWEM’s new Policy Position Statement on SuDS includes ten recommendations to improve SuDS implementation in England and an overview of the key issues affecting SuDS delivery.

Thanks to the SuDS and Water Reuse policy leadership group for their input when creating this Policy Position Statement.
