Abstract The publication presents the main types of incidental events in collective water supply system. The special attention was addressed to the incidental events associated with a decrease in water quality, posing a threat to the health and life of inhabitants. The security method against incidental contamination in the water source was described.

The City

This paper provides a detailed look into the historical development of the water supply system of a big industrial city and its impact on the river environment and needs of the wastewater treatment system. The city of Brno, Czech Republic, was chosen for this study because it has a long history in the field of water supply, and the city has changed rapidly over the last 200 years. The city’s development necessitated an adaptation of drinking water sources, most significantly the use of the Březová nad Svitavou facility, which resulted in a change of condition of the Svitava River. The notable decrease in river flow, aided by industrial development of settlements within the Svitava River catchment between 1850 and 1950, strongly contributed to the spread of river pollution. However, the construction of wastewater treatment plants during recent decades led to a restoration of river quality and, consequently, of the entire environment of the Svitava River catchment. This paper also presents a view on activities connected with the long term surface water quality monitoring and improvement with regard to water quality conditions in spring areas and the river network influenced by the water supply system.

Water Composition

Затронуты вопросы, связанные с организацией контроля качества питьевой воды, в том числе производственного контроля, в соответствии с действующими санитарными и отраслевыми нормативными документами. Приведен опыт ГУП «Водоканал Санкт-Петербурга» по формированию программ производственного контроля, выбора контрольных точек в распределительной сети с учетом оценки риска при ухудшении качества воды у потребителя. Обозначены инициативы по внесению в нормативные акты, касающиеся организации производственного контроля, обязательности использования автоматизированных систем контроля качества воды по основным индикаторным показателям (температура, мутность, цветность, рН, общий органический углерод, остаточный хлор). Это позволит повысить эффективность управления системой водоснабжения, оперативно реагировать на изменения состава воды, проводить постоянный мониторинг состояния устойчивости системы с переходом на цифровые технологии («умный водоканал»). The issues related to the arrangement of the drinking water quality control, including in-process monitoring, in accordance with the current sanitary and sectorial regulations are touched upon. The experience of SUE «Vodokanal of St. Petersburg» in developing production control programs, selecting control points in the distribution network with account of the risk assessment in case of water quality deterioration at the consumer’s tap, is presented. Initiatives for including into the statutory regulations on the arrangement of production control, the mandatory use of automated water quality control systems for the main indicator values (temperature, turbidity, color, pH, total organic carbon, residual chlorine) are outlined. The amendments will provide for improving the efficiency of the water supply system management, responding promptly to the changes in water composition, and continuously monitoring the state of the system sustainability with the transition to digital technologies («smart water utility»).
