The development of protocols for an efficient monitoring of rivers quality is extremely important for urban planning. This paper shows up the Rapid Urban River Assessment Protocol (RUAP) and the results of its application in the Palmital River, located in an area of public water supply in the Metropolitan Region of Curitiba (RMC), in the State of Paraná - Brazil. Four points were analyzed in the lower third of the river and it was figured out with low quality status of the river and with environmental degradation. RUAP was proved to be a simple and accessible tool for monitoring river environments and that can be used by environmental agencies, as well as in formal and informal education of the population, supporting the popular participation in decision-making involving urban plannings.

An evaluation of the water quality at the hatchery of Tanjung Riau was conducted to understand the water quality status at the several place of the hatchery unit such as brood stock tanks, larva rearing tank, water storage tank, fi ngerling tank as well as the source of the water supply. The water quality status of Tanjung Riau generally is in a good condition to support the hatchery activities, but for turbidity and salinity were in the exceed and below the normal status and its infl uence on the spawning activity. To overcome the problem on the spawning of the brood stock, the improving of water supply with higher salinity and low turbidity should be set up to ensure the succeeded of the spawning.Key words : Water quality, grouper brood stock, hatchery,Tanjung Riau Batam

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.
