1. Professor David Butler Urban Water Research Group Imperial College London SUDS-related research SUDSNet meeting U. Sheffield 30 th December 2005

2. The WaND project Aim To support the delivery of integrated, sustainable water management for new developments by provision of tools and guidelines for project design, implementation and management

4. Project organisation Decision support WP9 Wastewater WP3 Water supply WP1 Recycling WP7 SUDS WP10 Stormwater WP2 Toolbox WP6 Envir health WP5 Decision- making WP8 Planning WP11 Risk & innov WP14 Socio-econ WP4 Household data WP12

5. SUDS-related work packages WP2: Stormwater (HRWallingford/CEH) WP10: SUDS performance at development scale – interactions with rainfall and groundwater (CEH/Sheffield) WP6: Toolbox development (Imperial)

6. WaND tools at three scales: 1.Large (regional, sub-regional)  Site Selection 2.Medium (site)  Technology Optioneering  Suitability for application evaluation 3.Small  design WaND toolbox

7. The user: 1.identifies a suitable site for the new urban development (Screening Tool), 2.identifies promising technologies to manage the urban water flows and investigates their interactions (Optioneering Tool) 3.identifies suitable sites within a given new development to place the identified technologies (Suitability Evaluation Tool) 4.carries out design of technology options

8. Screening tool Excel-Based GUI (development phase) Input GIS form Multiple Scenarios (Ecocentric/RPG12/Equal Importance)

9. SUDS types and site suitability criteria Infiltration SUDSStorage/RetentionPrevention Soil permeabilityPublic Space availabilityIn-house space availability Proximity to existing buildings Public health risk in the vicinity of schools and playgrounds Need for/acceptance of non-potable water use within the household Distance to the water tableLand priceResident’s financial potential to maintain the system properly Proximity to contaminated sites Slope and site morphology Local ground stabilityDownstream location with respect to impact of storage on the drainage system Proximity to groundwater vulnerability/protected zones Slope and site morphology
