Public water supply system is a system of structures under the unified management and supervision that provides, collects, treats, and delivers water to the users. Water sources are all public waters ? groundwater or surface water ? from which the public water supply systems abstract water (springs of groundwater, springs of water with surface water inflow, running waters, natural and artificial lakes). Water provided is treated water, i.e. water went through the treatment process aimed at obtaining pure drinking water (sludge, filtrating, chlorinating, etc.), where water chlorinated or distilled is not considered to be processed. Water losses are volumes of fresh water lost during the transport between abstraction point and usage point, between points of use and re-use, including leaking, fractures, evaporating and errors in water measuring.
