Who should attend?

  • Water and environmental professionals
  • Stormwater engineers
  • Landscape architects
  • Urban planners
  • Developers

Key topics

  • Introduction to WSUD/IWCM concepts
  • Conceptual catchment modelling (Rainfall-Runoff and Pollutant exports)
  • Formulation of treatment strategies - understanding of fundamental processes
  • Pathway to WSUD/IWCM implementation
  • WSUD sizing – things to be considered
  • Stormwater harvesting concepts
  • Optimised use of alternative water sources
  • WSUD/IWCM case studies
  • Common errors in WSUD/IWCM practices


  • Provide South African professionals and decision makers with insights into the latest developments, technologies and case studies related to WSUD and GI technology
  • Bring professionals from all sectors, i.e. academics, government officials, consultants and private sector together to discuss not only theoretical aspects, but also practical features, e.g. costs, implementation challenges, possible strategies, lessons learnt, etc.
  • Demonstrate how software tools developed by eWater Solutions visualize, analyse and assess different strategies for improving urban stormwater management
  • Present MUSIC (Model for Urban Stormwater Improvement Conceptualisation) which is the widely used stormwater modelling tool and leads the way in decision support for stormwater quality management and water sensitive urban design.
  • Present the successes of this user friendly modelling tool for both simple and highly complex urban stormwater systems.
  • Introduce the various GI devices and the application of these devices within a treatment train
  • Build on participants’ understanding of the physical, chemical and biological processes taking place in urban stormwater treatment systems to cover the theories adopted to model these processes
  • Discuss the challenges and the formulation of treatment strategies along with typical case studies and international experiences. Can these successes be superimposed into our South African environments and what should be considered to make successes relevant to our challenges?

Background Seminar Information

Managing urban waterways is challenging, requiring agreement among large number of stakeholders with competing interests. To protect the environment and South Africa’s ecosystems, we need an approach that recognises the environmental impacts of urbanisation, the linkages between land and water management and the importance of community values and involvement. The recent drought experienced in parts of South Africa must make us realise the challenge of securing reliable water supplies and making our communities more resilient to future climate challenges. Major initiatives promoting water conservation and water efficiency such as stormwater harvesting are gaining prominence, particularly in respect of the of the provision of an alternative water source.

A new paradigm is emerging in South Africa with regard to recognising sustainable approaches to stormwater management. This concept, variously referred to as Low Impact Development (LID) or Green Infrastructure (GI) or Sustainable Urban Drainage Systems (SUDS) or Water Sensitive Urban Design (WSUD) or Integrated Water Cycle Management (IWCM), has gained widespread recognition, especially in terms of urban stormwater runoff quantity and quality control. The South African Government has called on municipalities to take a ‘back to basics’ approach which ultimately aims to improve the functioning of municipalities to better serve communities by getting the basics right. The premise is that by incorporating GI / WSUD into our conventional built infrastructure environments, municipalities’ will be better able to serve communities

This is a call for new ideas on:

  • how to build infrastructure in a way that satisfies multiple objectives yet still meets the needs of the people it serves,
  • how to make health waterways, and
  • how to integrate water into the landscape to enhance visual, social, cultural and ecological values.


Ashis Dey, PhD., eWater, Australia.

Dr Ashis Dey is Deputy CEO of eWater Solutions. He has over 20 years’ experience in hydrology, hydraulics and water resources. Dr. Dey has extensive experience in leading the development of several well recognised stormwater modelling tools. In the last decade he led various national and international water modelling projects and peer reviewed many key models. He has delivered more than 100 training courses in various countries in recent years. Dr Dey has a Bachelor in Civil Engineering; Masters and PhD on flow and sediment modelling in rivers and floodplain. He has been the recipient of several academic awards throughout his career. He is a member of the Engineers Australia and American Society of Civil Engineers.


Gary Morgan, MSc., EnviroSource, South Africa.

Gary is a Director at EnviroSource. He has 10 years’ experience in water, waste and remediation. Gary specialises in the fields of hydrology, water resources, hydraulic modelling, flood studies, water quality sampling techniques and monitoring programs, contaminant investigation/remediation, geohydrology, installation of appropriate monitoring equipment for parameters estimation (surface and subsurface) Gary has worked in Australia and recognized the advantages of building a relationship with the Australian specialists for their strong background of stormwater practices.

This seminar is supported as a capacity building and networking event by the South African Water Research Commission’s and contributes to the Water Sensitive Design Community of Practice programme which is hosted by the Urban Water Management research unit at the University of Cape Town.
