Sustainable Urban Drainable Systems for Management of Surface Water

Abstract

Sustainable Urban Drainage Systems (SUDS) provide a system by which water drainage can be managed as closely as possible to what nature has intended, before the runoffs from urban development enter the watercourses. The system removes water quickly and efficiently in a sustainable manner and should be included in the masterplanning for building and urban development wherever possible. The SUDS concept is an integrated approach to surface water management, which equally considers quality, quantity, and amenity aspects to provide a more pleasant habitat for people as well as to increase the biodiversity value of the local environment. The growing demand for housing and commercial developments in the twenty-first century, as well as the environmental pressure caused by climate change, has increased the focus on sustainable construction and SUDS. The management of water quality is required by the European Union Water Framework Directive. Stakeholders should be consulted in every development for masterplanning to include SUDS to minimize impact on the local environment and land use; and also to mitigate risk of flooding and pollution on watercourses. There should be adequate care of the environment, as well as social and economic considerations in building development. Learning outcomes: On successful completion of this chapter, students will be able to: (1) Understand the requirements for sustainable surface water drainage for a building development. (2) Grasp the concept of sustainable urban drainage systems and the treatment train (sequence). (3) Have knowledge of SUDS techniques and their applicability. (4) Scope study, survey of ground soil, and hydrology characteristics of the site. (5) Appreciate land use and planning consent. (6) Gain insight into SUDS management.
