Sustainable Drainage Systems (SuDS) make a vital contribution to managing local flood risk and water quality whilst providing opportunities for  biodiversity and amenity.  Following the Ministerial Statement (Dec 2014), SuDS are expected in all new major developments. Over time knowledge and experience has improved and this training will share the latest good practice in the delivery of high quality multi-benefits SuDS. 

This course has been developed to complement the CIRIA’s SuDS guidance - The SuDS Manual (C753) and the Welsh Statutory standards for SuDS. The training programme will enable practitioners to efficiently plan, design, construct and manage SuDS schemes.
