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»).

Mining cities have undergone the process of extensive exploitation, which always results in a series of water issues. Integrated water resource management is necessary in improving water supply, allocation and quality without damaging economic development. This article constructs a linear optimization model including a ‘Top-Down’ socio-economic mode, and ‘Bottom-Up’ water quality control and water supply–demand modes with integrated water resource management focused on water allocation and water reclamation. Based on computer simulation, the model can propose a water resource management under the constraints of water supply–demand and water quality control, and the model can precisely predict the influences of water resource management on economic development, water utilization and water quality. Taking Ordos, a Chinese national resource city, as a case study, this model addresses a detailed water resource management, including a water allocation plan among industries and water reclamation plan with technologies, selection, arrangement and subsidies. The implementation of water resource management can fulfill multiple objectives on water quantity, water quality and sustainable economic development. This study indicates that water resource management with a comprehensive dynamic model can be a maneuverable approach to realize the sustainable development of economic growth and water resource utilization, as well as formulate the regional development plan.
