SuDS in London - a guide

Info

7.5 Best value Natural capital is defined by the Natural Capital Committee (NCC) as ‘those elements of nature which either directly provide or underpin human wellbeing’. Liveability and wellbeing influence how value for society is perceived. CIRIA Research Project RP993 states that best value is not about cheapness. It is the opportunity to seek and obtain best overall value. A SuDS approach can be cheaper than piped solutions; it can also deliver considerable wider benefits, as this guidance illustrates. Sustainable surface water management can contribute to a step-change in the resilience of London’s drainage infrastructure and the quality of its urban realm.
