Проведенный анализ современных нормативноправовых документов и практики оценки физического износа структурно сложных объектов водопроводноканализационного хозяйства показал, что современные методы оценки не учитывают особенности этих объектов. Выявлены факторы, влияющие на структуру показателей оценки физического износа по основным группам и элементам объектов водопроводноканализационного хозяйства. На их основе разработан алгоритм оценки физического износа объектов с применением рискориентированного подхода для трех уровней: объект, технологические элементы объекта (сооружения), функциональные элементы в составе сооружений (здания, оборудование). Использование алгоритма позволяет разработать рекомендации по корректировке периодичности и частоте проведения мониторинга показателей уровня физического износа объектов централизованных систем водоснабжения и водоотведения и их элементов. Практическое применение разработанного алгоритма будет способствовать внедрению современных подходов по управлению рисками, связанными с уровнем физического износа и оценкой вероятности потенциальных негативных последствий природного, антропогенного и другого характера. Внедрение алгоритма позволит также устанавливать уязвимые области и проводить предупредительные мероприятия в отношении возникновения угрозы нарушения обязательных требований, в том числе меры по снижению рисков (техникотехнологическое обновление зданий, сооружений, оборудования). Это необходимо для объективного и обоснованного планирования капитального ремонта, восстановления и развития объектов водопроводноканализационного хозяйства и их элементов.The paper analyzes current regulatory documents and experience in the field of assessing the deterioration of structurally complex water supply and sanitation facilities. The paper shows that modern assessment procedures do not take into account any features of such objects. The paper identifies factors that affect the indicator framework for assessing the physical deterioration of the main groups and components of water supply and sanitation facilities. Based on these factors, the paper proposes an algorithm for assessing the physical deterioration of facilities using a riskoriented approach for three levels: an object itself, its engineering components (facilities), and their functional elements (buildings, equipment). The paper indicates that the use of the algorithm would provide for developing recommendations for adjusting the frequency of monitoring indicators of the physical deterioration level of facilities of public water supply and sanitation systems and their elements. The implementation of the developed algorithm would contribute to the successful introduction of advanced approaches to managing risks associated with the level of physical deterioration and assessing the probability of potential negative consequences of natural, anthropogenic, and other origins. The introduction of the algorithm would also allow identifying vulnerable areas and taking preventive measures against the threat of violation of mandatory requirements including measures for reducing risks (technical and engineering renovation of buildings, facilities, equipment). This is required for objective and substantiated planning of overhaul, restoration, and development of water supply and sanitation facilities and their components.

Drinking-water supply and sanitation services are essential for human health, but their technologies and management systems are potentially vulnerable to climate change. An assessment was made of the resilience of water supply and sanitation systems against forecast climate changes by 2020 and 2030. The results showed very few technologies are resilient to climate change and the sustainability of the current progress towards the Millennium Development Goals (MDGs) may be significantly undermined. Management approaches are more important than technology in building resilience for water supply, but the reverse is true for sanitation. Whilst climate change represents a significant threat to sustainable drinking-water and sanitation services, through no-regrets actions and using opportunities to increase service quality, climate change may be a driver for improvements that have been insufficiently delivered to date.

В настоящее время в России принципиально изменился подход к процессу создания новой нормативной базы и контролю качества продукции. АО МосводоканалНИИпроект уже 80 лет занимается проектированием систем водоснабжения и водоотведения с использованием нормативноправовой базы РФ. Институт не только проектирует, но и имеет большой опыт по созданию нормативных документов (санитарных норм и правил, сводов правил и др.). Проведенный анализ нормативноправовой базы в сфере проектирования, строительства и эксплуатации систем водоснабжения и водоотведения показал, что на федеральном уровне этот вопрос решен, однако на региональном уровне требуется его дальнейшая глубокая проработка. Нередко требуется доработка, а в некоторых случаях и переработка утвержденных ключевых документов. Избежать недоработок в нормативной базе возможно лишь при тщательном анализе технических и технологических решений с привлечением широкого круга специалистов и при корректном внесении изменений в действующие нормативноправовые акты.At present the approach to the process of developing a new regulatory framework and product quality control has been essentially changed. MosvodokanalNIIproject JSC already 80 years has been designing water supply and sanitation systems with the use of the RF regulatory and legal framework. Aside from designing the Institute has been well experienced in developing regulatory documents (sanitary norms and rules, codes of practice etc.). The analysis of the regulatory and legal framework conducted in the field of designing, constructing and operating water supply and sanitation systems shows that this matter has been settled at the federal level however, at the regional level its indepth analysis is needed. Every so often improvement and, in some cases, revision of the approved key documents is required. Avoiding shortfalls in the regulatory framework is possible only with the careful analysis of the technical and technological solutions involving a wide range of experts and with the correct amendments to the effective regulatory and legal acts. Key words: regulatory and legal framework, water supply and sanitation systems, design, construction, operation.

To achieve the Millennium Development Goals for urban water supply and sanitation ∼300,000 and ∼400,000 people will have to be provided with an adequate water supply and adequate sanitation, respectively, every day during 2001–2015. The provision of urban water supply and sanitation services for these numbers of people necessitates action not only on an unprecedented scale, but also in a radically new way as “more of the same” is unlikely to achieve these goals. A “new paradigm” is proposed for low-cost urban water supply and sanitation, as follows: water supply and sanitation provision in urban areas and large villages should be to groups of households, not to individual households. Groups of households would form (even be required to form, or pay more if they do not) water and sanitation cooperatives. There would be standpipe and yard-tap cooperatives served by community-managed sanitation blocks, on-site sanitation systems or condominial sewerage, depending on space availability and costs and, for non-poor households, in-house multiple-tap cooperatives served by condominial sewerage or, in low-density areas, by septic tanks with on-site effluent disposal. Very poor households (those unable to afford to form standpipe cooperatives) would be served by community-managed standpipes and sanitation blocks.

The paper is devoted to the study of the features of mathematical modeling of water supply and sanitation systems. These systems are complex systems consisting of branched pipeline networks, structures, installations and equipment. In this case, the work of all elements must be linked to each other. This task is very diffi cult due to the presence of a large number of parameters and technological processes occurring in water supply and sanitation systems. Therefore, in practice, diff erent types of modeling, including mathematical, are used to solve these problems.
