SuDS aim to mimic the way water moves naturally in and around a site and provide a more sustainable approach to managing water. This differs from conventional drainage systems where rainwater runs quickly off hard surfaces, straight into drains and then into rivers, often carrying pollution with it.
SuDS involve a range of techniques such as green roofs, rainwater harvesting, permeable paving and landscape features such as ponds and wetlands.
There is a SuDS solution for every situation.
Benefits of SuDS
SuDS provide a range of benefits over conventional drainage systems:
- Reduced flood risk – SuDS slow down the flow of rainwater from a site by filtering and storing it. This reduces pressure on our overstretched drainage system and therefore reduces the risk of flooding, especially after heavy rainfall. This is particularly important as our drainage system is under increasing pressure due to development and the increased risk of heavy rainfall due to climate change
- Improved water quality – SuDS features, such as green roofs and permeable paving, filter and clean rainwater on site. This ensures water entering drains and then Haringey’s rivers are free of oil and pollutants which can harm wildlife
- Benefits for people and wildlife – SuDS creates opportunities for rainwater recycling and for creating attractive water features which support wildlife. SuDS also reduce the need for expensive conventional drainage systems, and thus can provide cost savings
