The course predominantly targets mid-career professionals dealing with technical aspects of drinking water transport and distribution, working for water supply companies, municipal assemblies or consulting bureaus. The prerequisites include a BSc degree in Civil Engineering or similar technical background, general PC-computer knowledge (word processing, spreadsheets) and good English command. The course is however designed to start from scratch on hydraulics and other technical aspects and is as such, in theory, also suitable for 'softer' professional backgrounds where multidisciplinary work in teams would be taking place as a follow-up; for instance, for rural WATSAN experts working for NGOs.
The main objectives of the module are to introduce the basics of planning, hydraulic- and engineering design, construction, operation & maintenance of water transport and distribution systems.
Introduction to Water Transport and Distribution:
Main objectives and components of WTD systems;
Water demand categories, patterns, calculation and forecasting;
Steady-state hydraulics of pressurised flows, single pipe calculation, branched and looped networks, pressure driven demand;
Hydraulics of storage and pumps;
Hydraulic design: choice of supply scheme, network layouts, design of pumping stations, power requirements and energy consumption;
Engineering design: choice of pipe materials, valves and other equipment;
Network construction: pipe laying, testing and disinfection;
Operation & maintenance: regular & irregular supply, network cleaning and rehabilitation.
Water Loss Management and Control:
Definition of non-revenue water and IWA terminology used in the sector;
Components of water losses, methods of reducing and controlling real- and apparent network losses;
Quantification of leakage in distribution systems, leak location and repair techniques, pressure management.
