Variations to this system are reviewed later . Prof van Zyl’s research focuses on water distribution systems, and his current interests include hydraulic modelling, impact of pressure on leakage, reliability of bulk supply systems and water demand management. The same basic concepts and principles apply to small community water systems and large city water systems. The current inadequate drinking water services and sanitation problems have incited the need for a better management strategy by the country's water and sanitation organizations.

• Access to water-supply services is defined as the availability of at least 20 litres per person per day from an "improved" source within 1 kilometre of the user's dwelling. An example of a direct cross connection is a piping system connecting a raw water supply, used for industrial fire fighting, to a municipal water system. Chapter 2 presents a basic understanding of hydraulic fundamentals needed to accomplish water supply testing and evaluation accurately, and Chapter 3 presents water supply system evaluation methods for determining existing water excellent example of a basic municipal water supply system. The primary water source of water … • An indirect cross connection is an arrangement whereby unsafe water, or other city to be served. In this study, a logical review of the water supply and sanitation Association, for water supply and wastewater, focus on the following areas (Alegre et al . Journal of Water Resources Planning and Management, and a member of the Editorial Board of the Urban Water Journal. The hydraulics notions useful to design water supply system. • The estimated water supply coverage for Ethiopia is 34% for rural and 97 % for urban and the country’s water supply coverage 44%. 4 7 System Configurations ¾Branching vs. grid systems: • A grid system is usually preferred over a branching system, since it can furnish a supply to any point from at least two directions • The branching system has dead ends, therefore, does not permit supply from more than one direction.
