SUDS - Engineering Aspects: Introduction


The course is based on "The SuDS Manual" published by CIRIA. SuDS are gradually attaining acceptance as the preferred method for draining surface water from new developments. For SuDS to operate correctly they require careful attention to the engineering aspects and an understanding of what problems can arise. This course is aimed at the engineering aspects of SuDS design rather than the amenity and water quality aspects.

Aims & Objectives:

The course will enable delegates to develop a deeper appreciation and understanding of sustainable drainage systems:

  • Why the EA requires SuDS on all new developments
  • What is required of site investigations to BRE365
  • What is involved in estimating green field run-off
  • Open channel flow with particular reference to swales
  • Adoption and maintenance issues
  • How to integrate SuDS into urban layouts and the need for early engineer involvement

Delegates should finish the course understanding:

  • why SuDS are necessary
  • the types of SuDS available and their uses
  • what we mean by "the management train"
  • what is required of the Site Investigation procedure for determination of infiltrations rates
  • how infiltration rates are calculated
  • how these rates are used in the design and sizing of infiltration device
  • how to estimate green field run-off rates
  • how to calculate open channel flow capacities
  • how to integrate SuDS into and urban layout
