Pressure Management
in Water Distribution Systems 13 – 17 April 2015, University of Cape Town
Introduction
Municipal water distribution systems often supply water at pressures significantly higher than the minimum required for good service. International research over the last two decades has shown that these excessive pressures have several negative effects on distribution systems, including higher pipe failure rates, larger leakage rates and reduced capital service life. This has led to the wide use of pressure management, in which pressure control valves are used to optimally manage the pressure in discrete network zones. The Water Distribution Systems research group at UCT has been involved in ground-breaking research in the field of pressure and leakage, and is working closely with industry on pressure management problems.
Course aim
The aim of this course is to provide a structured introduction to the theoretical and practical aspects of pressure management in water distribution systems.
Course content
The main topics that will be addressed in the course are as follows:
Introduction to water losses: International Water Association water loss categories; Infrastructure Leakage Index (ILI) and water loss benchmarks; water loss components and water loss management.
Pressure in water distribution systems: Static and operating pressures; transient pressures; pumped systems; district managed areas (DMAs); pressure management areas (PMAs), average zonal night pressure (AZP) and day-night factors.
Pressure and burst frequency: Factors influencing burst-frequency; relationship between pressure and burst frequency and modelling burst frequencies.
Pressure and leakage rate: Orifice equation; power leakage (N1) equation; FAVAD equation and the leakage number.
Leak hydraulics: Orifice parameter estimation; laminar and transitional flow and implications for leakage.
Leak-soil interaction: Darcy flow; non-Darcy flow; suspended flow; pipe erosion and implications for leakage.
Water demand: Factors influencing water demand; volume and time based demands; modelling pressure-dependent demands and minimum night flow demands.
Leak area variation with pressure: Fixed area leaks; elastic deformation; viscoelastic deformation; plastic deformation; fracture and implications for leakage flow.
Modelling system-wide leakage: Leak types and their distributions; modelling system leakage parameters, day-night factors and the link between ILI and system leakage.
Pressure management zones: Principles of DMA and PMAs, isolating zones, integrity testing and management.
Pressure management installations: Control valve principles, pressure reducing valves, valve controllers and designing pressure management installations.
Economic analysis: Costs, benefits and economic analysis of pressure management.
Management of pressure management systems: Operation and maintenance requirements; dealing with common system and consumer problems and ensuring sustainability.
Case studies: Several pressure management case studies will be presented and discussed.
Site visit: A site visit to an operational pressure management system.

Course presenters
Prof Kobus van Zyl holds Bachelor and Master’s degrees in Civil Engineering, and a Diploma in Scientific Computing from the University of Johannesburg. He obtained a Ph.D. in Civil Engineering at the University of Exeter in 2001. He is a registered Professional Engineer, a member of the South African Society of Civil Engineering, American Society of Civil Engineers and the International Water Association, and a Fellow of the Water Institute of Southern Africa. In 1998 Prof van Zyl chaired the 10
th
Water Distribution System Analysis (WDSA) Conference in the Kruger National Park. This is one of the two leading international conference series on water distribution systems, and was the first time a WDSA conference was held outside the USA. He has twice been awarded the Best Paper prize in the Journal of the South African Society of Civil Engineering, and is an Associate Editor of the Journal of Water Resources Planning and Management. The relationship between pressure and leakage is the core focus of Prof van Zyl’s research, and he has made a number of important contributions to this field. Prof van Zyl is currently the Assistant Dean: Academic Development in the Faculty of Engineering and the Built Environment at the University of Cape Town.
Mark Shepherd is a registered Professional Civil Engineer who is based in Durban. He has a total of 22 years’ experience in engineering and Government support contracts and has spent the last 14 years focusing on water demand management and Non-Revenue Water reduction projects, both nationally and internationally. He has served on the American Water Works Association’s International Council and is currently a member of the Repair or Replace, Pressure Management and Transient- Induced Leakage Committees of the International Water Association’s Water Loss Specialist Group. He has specialised in pressure management solutions in water distribution networks and is currently part of internationally-leading research on the impact of pressure on leakage and burst frequencies.
Course Information
Who should attend? This course will benefit engineering and technical staff at municipalities, bulk water suppliers and consultants who deal with pressure management. It is a technical course and thus a scientific or engineering background is required.
Format Lectures will be given over 5-days by the course presenters and selected experts on aspects of pressure management. The course is aimed at providing theoretical and practical knowledge and will include several hands-on calculation, modelling and design exercises, as well as a site visit to an operational pressure management installation.
Cost The CPD fee for this course is R9500.00 (as an educational activity, this fee is not subject to VAT). This fee includes a comprehensive set of course notes.
Certificates and CPD Points A certificate of attendance will be awarded to CPD participants. Participants need to attend 80% of the lectures to qualify for an attendance certificate. CPD participants can also request a formal university transcript, which will show this course as part of a Professional Development Career. Please note: If you are interested in attending this course for credit purposes, you will need to register for the Masters Programme or as an occasional student. If you attend the course as a CPD participant, credit cannot be claimed in retrospect. This course is registered with ECSA for the award of 5 CPD points. The ECSA course code is UCTPMWD15
