    This course introduces operators to the practical aspects of operating and maintaining small drinking water supply systems and treatment plants, with an emphasis on safe practices and procedures. Topics covered include the duties of small system operators, water sources, and treatment processes. A water distribution systems is one in which the drinking water is transported from the centralised treatment plant or well supplies to the service connection or consumers´ taps. These systems aim to preserve the quality and quantity of water, as well as maintain sufficient pressures in .

      Water Distribution Systems. The purpose of distribution system is to deliver water to consumer with appropriate quality, quantity and pressure. Distribution system is used to describe collectively the facilities used to supply water from its source to the point of usage. Requirements of Good Distribution System. Water quality should not get. distribution system. The same basic concepts and principles apply to small community water systems and large city water systems. For a basic understanding of these concepts, two illustrations are provided that include a relatively small water distribution system and a medium size water distribution system.

    Types of Public Water Systems A. Community Water System (CWS): A CWS has at least 15 service connections used by year-round residents or regularly serves at least 25 year-round residents. Examples of a CWS may include, but are not limited to, cities, villages, nursing homes and mobile home parks. B. Nontransient Noncommunity Water System. Non-Transient Non-Community Water System (NTNCWS): A public water system that regularly supplies water to at least 25 of the same people at least six months per year. Some examples are schools, factories, office buildings, and hospitals which have their own water systems.

The water quality integrity is a control of degradations as the water travels through distribution systems. The impacts of water quality can be caused by physical or hydraulic integrity factors. The water quality degradations can also take place within the distribution systems such as microorganism growth, nitrification, and internal corrosion.
