About the course

Water distribution systems use interconnected elements such as pipes, pumps and service reservoirs to convey treated water from one or more sources to customers spread over a wide area. Given that capital costs and ongoing maintenance and repair costs of these systems are often enormous, the need for more economic and efficient designs is very important. Water distribution systems are composed of three major components: pumping stations, distribution storage, and distribution piping. These components may be further divided into subcomponents, which in turn can be divided in sub-subcomponents. For example, the pumping station component consists of structural, electrical, piping and pumping unit sub-components. The pumping unit can be divided further into sub-subcomponents: pump, driver, controls, power transmission. The exact definition of components, subcomponents and sub-subcomponents depends on the level of detail of the required analysis and to a somewhat greater extent, the level of detail of available data. In fact, the concept of component-subcomponent-sub-subcomponent merely defines a hierarchy of building blocks used to construct the water distribution system.

The water distribution system operates as a system of independent components. The hydraulics of each component is relatively straightforward; however, these components depend directly upon each other and as a result effect the performance of one another. The purpose of design and analysis is to determine how the systems perform hydraulically under various demands and operation conditions. All engineers like to think that they produce good, safe designs that are operationally efficient and cost effective. However, it is rare for a designer to have the time to consider more than a handful of solutions to a problem. In the planning phase of a project there are often many alternatives to each individual component of a scheme. The number of different designs for a complete scheme can thus be extremely large, if not infinite. Even with detailed design, there are usually far too many possibilities for each to be considered and evaluated.

This state-of-the art course is designed to provide participants with a good overview of the latest methods, materials, techniques and tools for water system networking and pumping stations. The course will present an up-to-date overview of the current water network design procedures and develop basic guidelines to be followed in both the design and the redesign of water networks and pumping stations. The course treats the water network design problem in a comprehensive and systematic framework, starting with objectives and elaborating on various technical design features. It will show how to apply the fundamentals of various disciplines and subjects to produce a well-integrated pumping station that will be reliable, easy to operate and maintain and free from design mistakes. In a field where inappropriate design can be extremely costly, there is simply no excuse for not taking expert advice from this course. Further, the course will tackle the Industry-specific issues and problems that engineers face every day. It will cover design, installation, operation, maintenance, retrofitting and rehabilitation of water network system and pumping stations.
