In most developed countries, wastewater treatment plants are presently utilizing efficient purification technology meeting the sufficiency requirements of quality and quantity. However, in developing countries, the number of wastewater treatment plants is limited. As a result, the establishment of a connection between the wastewater collection system and wastewater purification plants is increasingly becoming a top priority for researchers. The aim of this article is to analyze wastewater collection and purification systems and establish the links between these two processes. In the present study, the efficiency of the present purification system at the Istanbul-Tuzla and Adana-Kozan plants was investigated with the aim of enhancing their performance. The findings pertaining to the model sewage system revealed a decrease in NH3-N by 20–70%, total nitrogen (T-N) by 25–75%, biological oxygen demand (BOD5) by 50–60%, chemical oxygen demand (COD) by 35–55% and suspended solids (SS) by 55–85%. As a result of studies performed in the Tuzla sewage treatment system, we can confirm that T-N decreased by 50–75%, suspended solid particles by 24–57%, and BOD5 by 34–57%, while 35–55% of COD was removed. Similarly, in the canal exit at Kоzan, BOD5 decreased by 40–55%, COD by 30–50%, SS by 25–45% and T-N by 5–40%.

The purpose of this economic and sector work (ESW) is to support the Republic Forum for potable water and sanitation (FOCARD-APS) member countries in improving the resilience of water supply and sanitation (WSS) services. This report summarizes the findings from seven country-specific assessments carried out in 2013 and 2014 that characterize the national disaster risk management (DRM) and climate change adaptation (CCA) frameworks and efforts designed to reduce the vulnerability of WSS services to disasters and climate change. This activity also supports the World Bank strategy for enhancing DRM in Central America. This analytical effort is the result of a comprehensive participatory process that contributed to building the analytical capacities of the institutions that conform the FOCARD-APS’s regional thematic group (RTG) for DRM. It involved thorough document reviews and two rounds of country visits for data collection, as well as consultation with national and regional experts. The findings of all assessments were validated through national and regional workshops by the RTG-DRM. Regional learning exchanges and study visits were organized as part of this activity to provide policy makers with concrete examples of approaches and potential measures for addressing disaster risk challenges from a WSS service provision perspective and through a broader political and sectoral scope covering policy development, financing, capacity building, and institutional reform.

From 2012 to 2014 water and sanitation service delivery assessments (SDA) have been carried out in seven selected countries in the East Asia and Pacific region under the guidance of the World Bank’s water and sanitation program and with valuable contributions of other development partners, such as United Nations Childrens Fund (UNICEF), WaterAid, and Asian Development Bank (ADB). Countries where SDA were carried out are Cambodia, Indonesia, Lao Peoples Democratic Republic (PDR), Papua New Guinea, Philippines, Timor-Leste, and Vietnam, while in Myanmar, a broad joint sector assessment took place by World Bank, UNICEF, ADB, and Japan International Cooperation Agency (JICA). SDA were implemented as a country-owned process led by key government agencies, and drew on the experience and methodology of similar assessments conducted in more than 40 countries (and states) in Africa, Latin America, and South Asia. It has three main components: a review of past water and sanitation access trends, a costing model to assess the adequacy of anticipated future investments, and a scorecard that allows diagnosis of bottlenecks along the service delivery pathways.

To evaluate and reflect the sustainability of services in the region, an overall sector sustainability assessment was done, taking into account four main dimensions: access to services, quality of services, efficiency of services, and financing of services. Each of these dimensions is measured through three simple and objective indicators. For each indicator, best practice values are established by looking at the best performers in the region, and countries closest to those best performers are deemed to have a more mature sector. A more complete description of the methodology to assess the sector sustainability is included in the Annex of the State of the Sector Regional Report from the Danube Water Program. The outcomes of this assessment for the Moldova water sector are presented, which also shows average and best practices in the Danube region. The Moldova sector sustainability score is 50, which is below the Danube average of 64, and is among the lowest scores in the region. The assessment shows that, on average, the country performs well in terms of collection ratio, nonrevenue water, and continuity of service. The main deficiencies of the Moldova water sector identified through the sector sustainability assessment are access to piped water and flush toilets, affordability, and investment level.

The outcomes of this assessment for the Czech Republic water sector are displayed in Figure 9, which also shows average and best practices in the Danube region. The Czech sector sustainability score is 88, which is much higher than the Danube average sector sustainability of 64, and is among the best practices in the region. The assessment shows that, on average, the country performs very well in terms of access to piped water and flush toilets, continuity of service, wastewater compliance, staffing level, collection ratio, and nonrevenue water. The main deficiencies of the Czech water sector identified through the sector sustainability assessment are operating cost ratio and affordability. The main sector challenges are: implementing reform regarding the regulatory framework of the sector. Within the framework of the 2014-2020 operational program for environment, the European Commission stipulated ex-ante conditions, requiring the Czech Republic to establish a regulatory office for the sector. Different alternatives are discussed at the governmental level, and regulatory impact assessment papers are being prepared; and facilitating sector strategic planning despite the heterogeneity of the utility ownership structure. Around 6,000 entities (owners, public services providers) operate in the water sector (Expert estimate). To some extent, the heterogeneity of those entities in terms of size, legal status, scope of competencies and interests prevent effective strategic planning, resource balancing, and efficient asset management of regional systems, including drought and water scarcity issues management. Addressing this situation could help implement more efficient sector planning.

This report analyzes the progress and challenges of 16 countries in the Danube watershed in delivering sustainable water and wastewater services to all, while meeting the European Union environmental acquis communautaire. After putting the services that are being delivered into context, the report analyzes the organization of services in the region and the level of access to services, that is, how well countries are doing in terms of providing access to water and wastewater services for the entire population. It then looks at the performance of the sector, including the quality of services provided and customer satisfaction with it. It also draws a picture of the efficiency of services, including whether they reflect accepted good practices. Finally, it analyzes the financing of services, looking at whether the financing of operation, maintenance, and investments is secured and affordable. The report draws largely from existing public data sources at the national and regional level, and consolidates them into a coherent, regional narrative, and analysis. The methods of analysis include horizontal comparisons among countries at a given point in time and trends within the countries or the region over a given period of time. Given shortcomings in the availability and comparability of data across 16 countries, the report seeks to encourage and inform a policy dialogue around sector challenges rather than provide a definitive set of policy recommendations.

This synthesis report details the process, outputs and intermediate outcomes of the World Bank’s Water and Sanitation Program (WSP) Technical Assistance (TA) to Support Government of India for implementation of the National Urban Sanitation Policy (P131963). The objective of this TA was to (i) strengthen urban sanitation services and target the urban poor by development of strategies for regulation, funds allocation, improved accountability mechanisms and implementation of inclusive sanitation policies at national level and in at least five states, with two of these low-income states (LIS). This was to be supplemented with (ii) enabling design and use of improved performance monitoring systems by Government of India, 3 states and 300 urban local bodies by 2015, and (iii) strengthen capacity of local urban government institutions to provide improved – inclusive and sustainable – sanitation services for all. This TA provides the building blocks for sustainable sanitation improvements which are being adopted and implemented as part of another TA (P131967) in Madhya Pradesh and Tripura to pilot and operationalize City Sanitation Plans (CSPs) towards outcome oriented sector improvements. The areas addressed in this TA include the following specific goals of the NUSP: open defecation free cities, and integrated city-wide sanitation. The TA provided assistance to central government and the states in putting in place various elements identified as necessary for sector improvement, including planning, provisioning and monitoring processes. The TA also identified the need for the cities to see opportunities for financial recovery of investments through reuse and recycle strategies, to strengthen the incentive for investment in sanitation improvements.

The severe conditions in Zimbabwe, which reached a nadir in 2008 and 2009, led to a collapse of basic systems including the reliability and safety of water supply and sanitation services, leading to an outbreak of cholera with more than 4,000 deaths and over 90,000 people infected. The World Bank provided Technical Assistance (TA) to the City of Harare to improve water and sanitation services in the period October 2012 to June 2014 to the value of approximately 600,000 US dollars. This Summary Note summarizes the key elements of the work undertaken and makes a set of recommendations to the City of Harare, the adjacent local authorities of Chitungwiza, Epworth, Norton and Ruwa, and Government of Zimbabwe to inform a strategic plan to improve water and Sanitation services in the greater Harare area. This Summary Note also sets out the context at the commencement of the TA, summarizes the work undertaken in the TA and the outcomes from this work, and makes recommendations for the way forward.

A partir del análisis de la problemática de la base aérea sede del GAORI en el manejo de sus drenajes, se estableció la necesidad de formular un plan de manejo integral del recurso hídrico, que involucrara los proyectos que demandaran este recurso. De tal forma que para suplir la escasez de agua tratada para consumo, se explora la posibilidad de optimizar los sistemas existentes y aprovechar los efluentes de aguas residuales tratadas y las pluviales en actividades que no demandan altos niveles de calidad en el agua requerida. Es así como se inicia con un diagnóstico que conduce al diseño delos componentes de la infraestructura considerados imprescindibles, como son la ampliación de la red de alcantarillado sanitario, los canales de drenaje pluvial de la pista aérea y la optimización de la laguna de oxidación existente, y se formulan alternativas de reuso. Finalmente, integrando los resultados obtenidos en la ejecución del trabajo se obtiene el plan de manejo integral del sistema de drenaje de la Unidad Abstract. From the analysis of the problems of the air base headquarters GAORI in managing your drains, the need to formulate a plan for integrated management of water resources projects that involved sued this resource was established. So that to meet the shortage of treated water for consumption, the ability to optimize and leverage existing systems effluent treated wastewater and storm water activities that do not demand high levels of quality in the required water is explored. Thus begins with a diagnosis that leads to the design of components considered essential infrastructure, such as the extension of the sanitary sewer, storm drainage channels of the airstrip and the optimization of the existing oxidation pond and reuse approaches formulated. Finally, integrating the results of the implementation of the work plan for the integrated management of the drainage system of the unit is obtained. Maestría

Many empirical studies have demonstrated the close relationship between a country’s economic development and its stock of infrastructure. Decades of deferred maintenance and lack of long-term financing have taken a heavy toll on Zimbabwe’s infrastructure that at one time was ranked at the top in Africa. Only the information and communications technologies (ICT) sector has been performing relatively well but its high tariffs add to the cost of doing business in Zimbabwe. The strategy in the infrastructure sectors is to encourage public private partnerships (PPPs) for the financing and execution of the different sub-projects. This strategy has been emerging in the electric power, road transport, and ICT sectors and is now being extended to water supply and sanitation. This review builds on the findings from an October-November 2013 mission that, upon the request of the Ministry of Finance, assessed the ministerial submissions for the 2014 public sector investment program (PSIP). The review concludes that the perception of the predictable policies is key for attracting responsible private partners for sustainable PPPs. The review recommends less risky options such as: (i) outsourcing operations of existing plants; (ii) lease contracts of existing plants; and (iii) sales of existing thermal plants. The review notes that the analytical multi donor trust fund (AMDTF) is programmed to close on June 30, 2014. It is of the essence to explore the possibilities to locate concessionary funding for a successor to the AMDTF given the high priority of additional studies in the power, water, and ICT sectors to prepare for the reforms suggested.

This report presents insights from the FY11 review of the World Bank s water portfolio. The report includes a methodological section followed by reviews of four broad areas: the water related commitments managed by the World Bank Group (WBG) for FY011; the water-related commitments of the International Bank for Reconstruction and Development (IBRD) and of the International Development Association (IDA) for FY11; water-related projects approved in FY11; and analytic and advisory activities (AAA), in particular economic and sector work (ESW) and technical assistance (TA), delivered in FY11. The focus of the report is on the new IBRD and IDA commitments in FY11, which are analyzed not only based on data provided in the World Bank s project database but also with data generated by reviewing the Project Appraisal Documents (PADs) using a newly developed questionnaire. Some of the key findings of the FY11 review are the following: Water-related IBRD and IDA commitments comprised about 95% of the overall WBG managed commitments for water. From FY02 to FY11 they grew more than five-fold, from US$1.3 billion to US$7.4 billion largely driven by increased commitments for water supply and sanitation. In FY11 a total of 105 water-related IBRD and IDA projects were approved. Commitments by region were largest for the East Asia and Pacific Region (EAP) and the South Asia Region (SAR) with 30% and 29%, respectively. With regard to the number of projects, Africa was by far the leading Region with 33 projects. Of the 105 water-related projects, only 22% were mapped to the Water Sector Board (WAT) and most of these were water supply and sanitation projects.

The report uses a theoretical model of a typical drainage basin, but the approach could be applied to many of the drainage basins managed by the holding company for water and wastewater in Egypt. This study set out to assess the relative health impacts of different wastewater management strategies on health in the Nile delta region using an approach similar to that used in the Ghana. The ultimate objective was to develop a framework for long-term investment planning based on monitoring of health and productivity impacts of proposed Bank operations which could be included in project Monitoring and Evaluation (M&E) systems. This will equip task teams to assess the risks and opportunities which arise due to the proposed shift from on-site to networked sanitation in four governorates where the Bank has wastewater operations. A secondary objective was to assess the extent to which existing legislation supports health riskbased planning. The conclusions of the study provide an indication of how such methods could increasingly be used to enable the selection of cost-effective and appropriate wastewater management strategies.

Over the past 25 years, Uganda has experienced sustained economic growth, supported by a prudent macroeconomic framework and propelled by consistent policy reforms. Annual Gross Domestic Product (GDP) growth averaged 7.4 percent in the 2000s, compared with 6.5 in the 1990s. Economic growth has enabled substantial poverty reduction, with the proportion of people living in poverty more than halving from 56 percent in the 1992 to 23.3 percent in 2009. However, welfare improvements have not been shared equally; there is increasing urban rural inequality and inequality between regions. Revitalizing economic growth and tackling persistent poverty will require addressing a number of challenges. These include alleviating infrastructure bottlenecks; increasing agricultural productivity; managing land, water and other natural resources; addressing demographic challenges; and confronting governance issues. The development and management of water resources is intimately linked to Uganda's continued development ambitions. Water can be both a positive force-providing productive input to agriculture, industry, energy and tourism, and sustaining human and environmental health-as well as a destructive one-to which the devastating consequences of floods and droughts can attest. The National Water Resources Assessment (NWRA) estimates that Uganda's total renewable water resources are about 43 million cubic meters (MCM), less than was estimated in the Ministry of Water and Environment's (MWE's) Sector Investment Plan (SIP) in 2009. About 13 percent of this is sustainable groundwater (5.67 MCM) and the balance is surface water (37.41 MCM). About one half of all districts in Uganda experience annual rainfall deficits-the difference between evapotranspiration and rainfall-ranging from slightly above zero to 400 mm. The frequency of rainfall anomalies below normal (or long-term annual average) is significantly greater than the frequency of rainfall anomalies higher than normal. The Uganda water Country Assistance Strategy (CAS) aims to assist the Government of Uganda (GoU) in identifying priority actions for building on successful outcomes, tackling remaining challenges, and exploiting opportunities in Uganda's water sector. The objective of the water CAS is to define the World Bank's strategic role in supporting GoU to better manage and develop its water resources. The recommendations of the water CAS are complementary to the World Bank Uganda Country Assistance Strategy (CAS) 2011-15 priorities for Uganda and consistent with the country's development objectives as defined in the National Development Plan (NDP) and water and related sector plans and strategies, which form the foundation of the World Bank Uganda CAS.

Man-made climate change is affecting water infrastructure in all regions of the world, affecting large numbers of people in their daily life and the development of their societies. As part of the World Bank Water Anchor's analytical and advisory work on water and climate change, consultants have investigated how private sector services to infrastructure may address the challenges related to climate change while, at the same time, improving development opportunities for people. This report, which is one of the outcomes of the work, addresses the role of private providers of non-financial climate change-related services with relevance for water infrastructure. This report investigates to need for additional services with regard to climate change and analyzes the potential for the private sector in providing these services. The analysis focuses on the water sectors likely to be affected by climate change, that is, water resources management, irrigation and drainage, hydropower, coastal protection, flood protection, urban water supply, and sanitation as well as water quality. In addition, opportunities for mutual engagement of public and private agencies are analyzed and the perspectives of market development are explored. The central aim of the report is to deepen our understanding of the opportunities for engaging private providers of climate change services in climate change adaptation combined with socioeconomic development opportunities.

The primary objective of the Southern Gobi Regional Environmental Assessment (REA) is to provide guidance for sustainable management of environmental resources in the future development of the Southern Gobi Region (SGR), development that will be led by rapid expansion of mining. The REA defines two development scenarios-a base-case and a high case-and explores their direct and indirect impacts on the natural environment, taking into account the opportunities, constraints, and vulnerabilities of the Gobi natural systems; the individual and cumulative direct environmental impacts and potential indirect impacts of the planned development; and, at a general level, the institutional capacity to manage the impacts. The REA target audience includes government officials at central, regional, and local levels; private sector investors and the consultants who are engaged for project design and environmental impact assessment; development finance organizations; and Mongolian civil society. This report was discussed in draft form at stakeholder workshops held in Ulaanbaatar and Dalanzagdad in April 2009 and has been revised to reflect comments received. Thanks are due to all those who joined those discussions. The report draws on information from workshops held in Mongolia, in May, September, and October 2008, and a field mission to the Southern Gobi Region in November 2008. Other information was obtained from various mining companies in Mongolia including Ivanhoe mines Mongolia, Inc., and its consultant Eco Trade; Rio Tinto; Energy Resources LLC; and South Gobi Sands.

Sustainability of wastewater collection, treatment and disposal options in the coastal region of the Republic of Croatia are discussed in the context of recent large-scale infrastructure investments. Past experiences are used for evaluation of development plans from a sustainability standpoint, bringing into focus the question of selecting the right strategy that would fulfill both population and environmental needs. The DPSIR approach (drivers-pressures-state-impacts-responses) is discussed in the context of the inherent complexity of the wastewater management sector and legislative ambiguities which create the opportunity for different development scenarios in partially sewered small and medium-size coastal municipalities.
