Drainage is a fundamental engineering service that is mainly out of sight and not appreciated by most people. This course will open the eyes and ears of the participants to see the various roles that different types of drainage system play in all our lives. Such as how drainage impacts: the food we eat, the safety of the roads we drive on and the pavements we walk on, the quality of our indoor air, the risks of flooding, the opportunities for water and energy reuse, our water supplies, natural habitats, our health and the impacts on local, national and world-wide environments.

Learning Outcomes:

The reasons that we need drainage in various places and applications

The basic science and mathematics behind drainage system design

Some of the impacts of drainage on the environment and how to address them with techniques such as SuDS and IWM

Understand the wide range of different philosophies and important parameters of drainage system design

Identify and understand the key Legislation and Standards relating to drainage in the UK

John Griggs

Water Consultant JPJN Partners Ltd

John is a water consultant who previously worked at the Building Research Establishment, providing technical input to Building Regulations and Standards. He has carried out laboratory and field testing of above and below ground drainage systems and written a number of publications on drainage design. He has served on many BSI, CEN and ISO committees. He has also worked for the Department of Trade and Industry (DTI) as the Construction Products Issues and Impact Manager and as Science Officer for the Chartered Institute of Plumbing and Heating Engineering (CIPHE). He has been awarded an Honorary Fellowship by the Society of Pubic Health Engineers (SoPHE) and a SWIG award from the Sustainable Water Industry Group.

  • My background is research, being at the Building Research Establishment (BRE) for nearly 30 years in the Water Centre. The work I was involved in was used in the UK building regulations as well as national and international Standards. Hence, I am well aware of the science behind many of the requirements in today’s Standards, Regulations and Directives. Whilst at BRE, I was seconded to the Department for Trade and Industry for over 3 years; where I was responsible for all construction products. I worked on the EU Emissions Trading Scheme, the F-gas Regulations and other draft legislation that embraced the whole construction industry; not just water.
  • Since then I have worked for the Chartered Institute of Plumbing and Heating Engineering (CIPHE) and lead a number of European research and development projects on topics that included: renewable heat storage systems, solar energy, and sustainable plastics pipe. I am now a consultant working with various clients on diverse topics such as: solid waste transport, Certification of products, forensic plumbing and training. I have been honoured to co-author two recent handbooks on water supply and drainage with some of the leading academics in the UK. 
  • I currently live in St Albans, where I have done so for all my life. I am married to my wife Penny and we have two sons. Our house is fitted with a number of water efficient appliances and fittings and our drainage system is fitted with mechanical valves. For many years I have monitored the water consumption and it is generally about half of the UK average per person consumption.
