Design Options

Из-за неравномерности распределения водных ресурсов по территории России многие населенные пункты и даже города не имеют своих источников водоснабжения и водоемов, куда можно было бы сбрасывать очищенные сточные воды. Для решения этой проблемы проектируются, строятся и развиваются групповые и районные системы водоснабжения и водоотведения. Протяженность таких систем насчитывает сотни и даже тысячи километров. На их строительство и эксплуатацию ежегодно требуются значительные финансовые средства. Поэтому вопросы выбора трасс, состава сооружений и особенно способов транспортировки воды и сточных вод, обоснования мест расположения водозаборов и очистных сооружений являются актуальными и требуют особого внимания и технико-экономического анализа проектных вариантов. Предлагается методика комплексной оптимизации параметров систем водоснабжения и водоотведения, позволяющая определять наилучшие способы транспортирования воды и стоков (трубопроводами либо в цистернах автомобилей), места устройства водозаборов, водопроводных и канализационных очистных сооружений, оптимальные трубопроводные трассы и автомобильные маршруты между этими сооружениями и абонентами. Due to the uneven distribution of water resources across the territory of Russia, many communities and even cities lack own water supply sources and water bodies where effluents could be discharge into. To address this problem, group and district water supply and wastewater disposal systems are designed, built and developed. The length of such systems is hundreds and even thousands of kilometers. Significant financial resources are required annually for their construction and operation. Therefore, the issues of the choice of routes, composition of the structures and especially methods of transporting water and wastewater, justification of locating water intakes and treatment facilities are relevant and require special attention and technical and economic analysis of design options. A method is proposed for the comprehensive optimization of the parameters of water supply and wastewater disposal systems that will provide for determining the best ways of transporting water and wastewater (by pipelines or in road-tankers), location of water intakes, water supply and wastewater treatment facilities, optimal pipeline routes and auto routes between these structures and customers.

Осадки городских очистных канализационных сооружений являются самым массовым технологическим отходом, создающим проблемы утилизации для любого города. Рассмотрены возможные методы обработки осадков сточных вод на городских очистных канализационных сооружениях городского округа Самара с целью их последующей утилизации. Обозначены причины и приведены документальные подтверждениянекорректности возложения ответственности за обращение с такими отходами только на организации водопроводно-канализационного хозяйства. Рассмотрен способ захоронения обезвоженного осадка сточных вод в обвалованном полигоне. Установлено, что обработанные на очистных сооружениях осадки относятся к V классу опасности для окружающей среды. Обработанные, стабилизированные, подсушенные, обезвреженные отходы осадков сточных вод (малоопасный осадок с песколовок при очистке хозяйственно-бытовых и смешанных сточных вод, практически не опасный осадок с песколовок при очистке хозяйственно-бытовых и смешанных сточных вод и избыточный ил биологических очистных сооружений в смеси с сырым осадком) могут быть использованы в качестве наполнителей бетонно-цементных смесей и органоминеральных удобрений или переданы для утилизации сторонним организациям. Sludge from the municipal wastewater treatment facilities is the most massive technological waste that causes trouble for any city. Possible methods of wastewater sludge treatment at the municipal wastewater treatment facilities of the Samara Urban District with the purpose of its further utilization are considered. The reasons are indicated and documentary evidence of the incorrectness of assigning the responsibility for processing such wastes only to the water and wastewater utilities is provided. The method of landfilling dewatered wastewater sludge in a ridged landfill is considered. It has been established that the sludge processed at the wastewater treatment facilities is referred to the V class of environmental hazard. Sludge subjected to the treatment, stabilization, drying and neutralization (low hazardous sludge from grit chambers for domestic and mixed wastewater treatment; almost non-hazardous sludge from grit chambers for domestic and mixed wastewater treatment and excess sludge from biological treatment facilities mixed with raw sludge) can be used as fillers for concrete-cement mixtures and organo-mineral fertilizers or transferred for disposal to outside companies.

С момента перехода государства на новую экономическую модель развития социально значимые отрасли остались в тени «локомотивов» экономического развития – топливно-энергетического и минерально-сырьевого комплексов. Отрасли народного хозяйства, не имеющие коммерческого интереса, отмирали полностью или сжимались до размеров возможной минимальной окупаемости. Данные изменения затронули и отрасль жилищно-коммунального хозяйства, в частности водопроводно-канализационное хозяйство. Катастрофическое состояние отрасли в настоящее время требует особого внимания и особых решений со стороны всех участвующих и заинтересованных сторон: органов государственной и муниципальной власти, органов контроля и надзора, операторов систем водопроводно-канализационного хозяйства, коммерческих организаций, высшей школы, профильного научного сообщества и населения. Одна из базовых отраслей народного хозяйства не должна находиться в таком состоянии и, несмотря на отсутствие экономической стабильности, необходимо сделать ее восстановление приоритетной государственной задачей, направив на это максимальные материальные и интеллектуальные ресурсы страны. Приведен пример концессионного соглашения, которое иллюстрирует один из возможных путей продления ресурса городского канализационного хозяйства с предельным износом. Since the transition of Russian Federation to a new economic model of development, socially significant industries have remained in the shadow of the «locomotives» of the economic development, i. e., the fuel and energy and mineral resource sectors. Branches of the national economy that had no commercial interest died out completely or shrank to the size of a possible minimum payback. These changes also affected the housing and utilities sector, in particular, the water supply and wastewater disposal systems. The catastrophic state of the industry currently requires special attention and special decisions on the part of all the stake holders: the state and municipal authorities, control and supervision bodies, operators of water and wastewater utilities, commercial organizations, higher education, the relevant scientific community and population. One of the basic sectors of the national economy should not be in such a state and, despite the lack of the economic stability, its restoration should be a priority state task directing the maximum material and intellectual resources of the country. An example of a concession agreement is given that can be a possible way to extend the resource of an urban wastewater disposal system with a wear limit.

Within Ireland, both the public water supply and group water scheme (GWS) sectors are crucial entities in the provision of water supply to individuals. In this study, variances in water charges and operation are assessed via an in-depth survey of 104 GWSs in order to establish the range in both domestic and commercial charges, and also to establish the factors influencing these charges within the rural water sector. Results are compared with the commercial water charges of the 34 local authorities involved in the provision of public water and wastewater services. Devoid of regulation, tariff setting is highly decentralised with substantial variations in connection, fixed and volumetric charges across both sectors. Greater transparency is essential to establish the full cost of supply to domestic and non-domestic consumers. Findings reveal average GWS volumetric charges to be 35% lower than public supplies, resulting in communities wishing to retain ownership of their schemes as there is much greater control over water pricing. Historic underinvestment has led to an infrastructure deficit and deficiencies within the public supply sector are discussed, such as inadequate revenue collection and high unaccounted-for water. Furthermore, recommendations are made towards effective operation and pricing in light of proposed government plans to establish a national water authority.

Modern wastewater treatment plants are often inappropriate for communities in developing countries. Such communities lack the funding, resources and skilled labour required to implement, operate, and maintain these plants. This research was conducted to investigate and establish an appropriate wastewater treatment system for the district of Gunung Kidul, Indonesia. Due to its lack of water during the dry season, this district is considered one of the poorest areas in the nation. First, wastewater was stored in septic tank units for a retention time of 26 days. Anaerobic conditions occurred, resulting in an 80% reduction of initial COD. The retained sludge was well stabilized with great potential, if dewatered, for reuse as fertilizer. Consequently, supernatant was separated for experiments consisting of lab scale aerobic sand filtering unit. Through filtration, further removals of COD (about 30%) and pathogens were achieved. Rich in nitrogen, the resulting effluent could be used for irrigation and soil conditioning. With faecal sludge and also a mixture of septic sludge and food waste, the hydrolysis stage of anaerobic digestion was examined. This paper discusses the laboratory findings in Karlsruhe and the design and implementation of a treatment system in Glompong, Indonesia.

New acts on wastewater disposal demand for higher process stability and effluent quality. The A-B process, a novel two step treatment system, meets these requirements in a cost effective way. Five full-scale plants have been put in operation over the last two years. The objective of this paper is to give an outline of the features of the A-B system in the context of the results of these full-scale plants. In spite of the extreme high load, the A-stage can be operated at a high reduction rate and is stable. Variations in the organic load and pH- and toxic shocks are leveled out and a constant, mainly soluble effluent is supplied. This implicates a low sludge production in the B-stage. As a consequence higher overall reduction rates are obtained as compared to conventional processes at the same sludge load. Very low and stable final effluent concentrations are observed in all full-scale plants. Of special interest are the possibilities of upgrading existing conventional treatment facilities, at minor costs, by incorporating the A-B technology. The A-B process therefore can be considered as a very promising, cost effective alternative for both existing and new wastewater treatment plants in responding to the increasing effluent demands.

The piped water supply in Lucknow was introduced in 1892 to serve the population of 2 Lacs. However, the population has risen exponentially since then from 2.1 million in 2001 to 2.86 million in 2011 according to the census data of the Government of India. In this paper, statistical analysis was done and it was projected that the population of Lucknow will be as high as 4.2 million in 2025 followed by 6.42 million in 2040. Since the water demand is proportional to the population, it is projected that present water demand of 550 million liters per day (MLD) would rise to the maximum of 1300 MLD in the year 2040 which is twice more than the present volume. The major concern of Lucknow city is the poor efficiency of wastewater treatment facilities which are deteriorating the quality of underground water and surface sources. The major concern lies in Gomti River. The wastewater generation in 2025 would be as high as 700 MLD while for the year 2040 it would be 1100 MLD. To meet the given figures a well-planned and effective wastewater treatment system has to be designed and implemented which may include centralized and decentralized treatment facilities in accordance with the need of the particular division followed by up-gradation of the present water supply and sewerage system. Care should be taken while discharging the sewage into river Gomti and other natural streams as it should strictly follow the prescribed standards by central state pollution control boards, also there should be the least disturbance of aquatic ecosystem. Furthermore, deterioration of the water quality must be minimized to a large extent.
