Abstract

© 2017 John Wiley & Sons, Ltd. All rights reserved. This chapter reviews rainwater harvesting (RwH) and sustainable drainage systems (SuDS), as well as existing approaches to integrate RwH and SuDS in England and Wales. A new design method is proposed for the design of dual-purpose RwH systems, and the method is subsequently used to assess the benefits of such systems for a case study development in Exeter, England. Benefits and limitations are discussed. Early studies which sought to appraise the ability of RwH to control stormwater discharges were undertaken during the WaND project. As part of this study, Kellagher and Maneiro Franco used hydraulic models to assess the overall reduction in stormwater runoff volumes and peak flow rates from a development where a large communal RwH storage tank was proposed. The chapter seeks to address the first step towards improved control of stormwater using RwH systems by proposing a retention and throttle RwH design method for application at UK development sites.
