Sustainable drainage systems for new developments mandatory

May 30, 2019 at 9:30 AM

Farmers in Wales planning a development on their property are reminded that they must now meet new standards for drainage. From January 7, 2019, all new developments of more than one dwelling house or where the construction area is 100m2 or more, will require Sustainable Drainage Systems (SuDS) for surface water. “The compulsory regulations introduced by the Welsh Government aim to reduce flood risk and improve water quality,” said Kathryn Williams, a chartered surveyor with Davis Meade Property Consultants. “All new development must be built in accordance with the new standards and be approved by the local authority overseeing SuDS before construction work begins.” “The regulations should help improve habitats for surrounding wildlife and diversity and reduce pollution. “ SuDS work by making use of landscape and natural vegetation to control the flow of surface water and reduce the risk of flooding. Designs can include ponds and permeable paving which slow down the discharge of surface water more than conventional piped drainage. “The sustainable systems are also designed to reduce surface water runoff and improve water quality while being more resilient and longer lasting than conventional drainage,” she said. “Planting trees can also help reduce run off on farms as can installing water butts to harvest rainwater,” she said.
