“…This characteristic of the allocation of diameters to pipes plays in favor of a correct hydraulic operation of the network and has a beneficial effect on water quality, see, e.g., the discussion in [121]. This is depicted in Figure 7.3 where the size of each diameter is proportional to the thickness of the arc 5 .…”

Results are reported from studies conducted using a unique laboratory-based, full-scale, temperature-controlled pipe facility to examine the impact of conditioning shear stress on discolouration risk, as characterised by bulk water samples (turbidity, iron and manganese) and biofilm pipe wall measurements. The facility uniquely allowed for replication of the dynamics of an operational network but with rigorous control, thus yielding fully representative results overcoming the limitations of bench-scale or operational studies. The effect of the daily variation in flow (and boundary shear stress) was observed to be greater than the effect of the average daily flow rate at reducing discolouration risk. This is useful for informing operation and maintenance strategies, specifically that regularly imposing cycles of flow variation are more effective than increasing total average flow rates at limiting discolouration risk. The application of such knowledge aids the development of cost-effective, proactive, operational interventions to manage discolouration.

“…A concept of creating a self-cleaning distribution system is presented in [366]. It is proposed to maintain a constant water flow velocity at a level of 0.4 m/s which is sufficient for a daily removal of deposits from a distribution system.…”

The relative critical overview of indicators, which set norms to the drinking water and are used as background for regulatory instruments of the USA, the EU, the WHO, Ukraine and Russia, has been revealed. The analytical review of current problems in drinking water preparation technology at centralized drinking water treatment plants has been delivered. The role of natural organic compounds of natural origin in drinking water quality has been revealed. The application of different technological measures to prepare high quality drinking water has been analysed and explained. The influence of condition of water distribution system on the drinking water quality has been evaluated. It has been cited the examples of modern technological systems of drinking water treatment. A new concept of supply the population with a quality drinking water has been introduced. It is based on representation the need to consume adequate water by a person, which is genetically safe, comprises no man induced alloys, and is characterized by occurrence of such natural substances and microelements that are easiest to digest for a body from water. KeywordsThe quality of drinking water · International regulatory instruments · Centralized drinking water treatment plants · Modern water treatment technologies · Man induced alloys, natural microelements · A new concept of supply the population with a quality drinking water Ecological and Hygienic Classification of Centralized Drinking Water Supply SourcesIn the Ukraine, the goal of creating and adhering to adequate quality and safety standards for drinking water is guaranteed by law. Legal documents such as the Water Code of Ukraine [1] and the Law of Ukraine "On drinking water and drinking water supply" [2] were written to uphold this goal. Codex found in these documents details a range of specific tasks centered around ecological, sanitary, and hygienic contents namely:• A complex development of interrelated regulatory documents (standards and norms) for ensuring an ecological and sanitary-hygienic safety practice in the field of use and protection of water and water resources;
