Tools for the design and evaluation of sustainable drainage systems (SuDS)

Our suite of tools provides users with the facility to estimate:

  • pre-development greenfield site runoff rates
  • storage volumes required to meet site flow rate controls
  • suitability of different SuDS for treating site runoff
  • infiltration and rainwater harvesting system storage volumes
  • the type of SuDS components applicable for specific site constraints
  • the impact of downstream boundary conditions on design return periods (joint probability analysis).
