Objetiva-se neste trabalho discutir a viabilidade da regulação subnacional do saneamento básico no País de acordo com o estabelecido na Lei no 11.445/2007. Foi analisada a viabilidade da regulação municipal em 2.523 municípios, com base na amostra do Sistema Nacional de Informações em Saneamento (SNIS) referente a 2005, mediante a aplicação de taxas de regulação de 1 a 3% do faturamento das concessionárias. Concluiu-se que a regulação local não apresenta viabilidade em 97% dos municípios pesquisados.; The objective of this paper is to discuss the feasibility and the alternatives for the sub-national regulation of the basic sanitation in Brazil, as established one in the Law 11.445/2007. We analyze a sample of 2.523 municipalities from the data set of the National System for Information on Water Supply and Sewerage Services (SNIS) of 2005, assuming regulatory fees ranging between 1% and 3% of the concessionaire’s revenues. We concluded that local regulation was impracticable for 97% of the municipalities in the sample.

The deficit of water and sewerage services is a historic problem in Brazil. The introduction of a new regulatory framework, in 2007, presented ways intending to overcome these deficits, among them, the providers efficiency improvement. This thesis aims to analyze the regulators performance regarding its ability to induce the efficiency of the Brazilian water and sewerage services providers. To this end, an analytical approach based on a sequential explanatory strategy was used, and it consists of three steps. In the first step, the Data Envelopment Analysis ( DEA ) was used to measure the providers efficiency in 2006 and 2011. The results show that the average efficiency may be considered high; however significant inefficiencies among the 29 analyzed providers were detected. The ones in the Southeast region showed better performance level and Northeast had the lowest. The local and the private providers were more efficient on average. In 2006 and 2011 the average performance was higher among non-regulated providers. In 2006 the group regulated by local agencies had the best average performance, in 2011, the best performance was the group regulated by the consortium agencies. To analyse the second step was used the Malmquist Index...

This paper provides evidence from eight developing countries of an inverse relationship between poverty and city size. Poverty is both more widespread and deeper in very small and small towns than in large or very large cities. This basic pattern is generally robust to choice of poverty line. The paper shows, further, that for all eight countries, a majority of the urban poor live in medium, small, or very small towns. Moreover, it is shown that the greater incidence and severity of consumption poverty in smaller towns is generally compounded by similarly greater deprivation in terms of access to basic infrastructure services, such as electricity, heating gas, sewerage, and solid waste disposal. The authors illustrate for one country -- Morocco -- that inequality within large cities is not driven by a severe dichotomy between slum dwellers and others. The notion of a single cleavage between slum residents and well-to-do burghers as the driver of urban inequality in the developing world thus appears to be unsubstantiated -- at least in this case. Robustness checks are performed to assess whether the findings in the paper are driven by price variation across city-size categories...

Using panel data, we estimate measures of density, scale and scope economies in four countries that differ substantially in their levels of economic development and in their piped water and sewerage coverage: Brazil, Moldova, Romania and Vietnam. We find evidence of economies of scale in Moldova, Romania and Vietnam. In Brazil, we cannot reject the null hypothesis of constant returns to scale. The results of this study show that the cost structure of water and sewerage utilities varies significantly within and between countries and over time.

Introducing private sector participation (PSP) into the water and sewerage sectors is difficult and controversial. Empirical studies on its effects are scant and generally inconclusive. Case studies tend to find improvements following privatisation, but they suffer from selection bias and it is difficult to generalise their results. To explore empirically the effects of private sector participation on coverage, we assemble a new dataset of connections to water and sewerage services at the city and province level based on household surveys in Argentina, Bolivia, and Brazil. The household surveys, conducted over a number of years, allow us to compile data before and after the introduction of private sector participation as well as from similar (control) regions did not privatise. Our analysis reveals that, in general, the share of households connected to piped water and sewerage improved following the introduction of private sector participation, consistent with the case study literature. We also find, however, that the share of households connected similarly improved in the control regions, suggesting that private sector participation, per se, may not have been responsible for those improvements. Results are similar when looking only at the poorest households. The share of poor households connected to piped water and sewerage increased similarly in areas both with and without private sector participation...

Using data from the International Benchmarking NETwork database, the authors estimate measures of density and scale economies in the water industry in four countries (Brazil, Colombia, Moldova, and Vietnam) that differ substantially in economic development, piped water and sewerage coverage, and characteristics of the utilities operating in the different countries. They find evidence of economies of scale in Colombia, Moldova, and Vietnam, implying the existence of a natural monopoly. In Brazil the authors cannot reject the 0 hypothesis of constant returns to scale. They also find evidence of economies of customer density in Moldova and Vietnam. The results of this study show that the cost structure of the water and wastewater sector varies significantly between countries and within countries, and over time, which has implications for how to regulate the sector.

This paper from the water sector in Uganda turns on its head conventional wisdom about capacity growth and how long it takes to effect enduring change. This example of a transformational process that was driven by passionate leadership and, contrary to popular development wisdom, was front-ended by short-term results producing initiatives that led to longer-term impact. The experience of the National Water and Sewerage Corporation (NWSC) in Uganda reflects a tripartite relationship among results achievement, capacity development, and performance improvement. Within a couple of years, NWSC went from being a fiscally and operationally dysfunctional utility to a financially sustainable and efficient service provider. The story of this transformation and conclusions on how charismatic leaders can cause profound changes within a short time frame are outlined in this paper.

National Water & Sewerage Company (NWSC), the Ugandan utility responsible for urban water delivery, was operating at a loss of Sh 348MM a month with performance indicators below African utility standards. In 1999, the Bank recommended that NWSC close down for good, after five years of intensive investments aimed at turning- around the utility. However, just three years later, the NWSC is hailed as a model by other African nations, corporations, and municipalities. What made the difference? Dr. William Muhairwe, the newly hired Managing Director declared a 100-day program focusing on targeted outputs. A sharp focus on results and "stretch" goals brought out the hidden reserve of capacity that already existed in the utility.

Our analysis reveals that, in general, connection rates to piped water and sewerage, improved following the introduction of PSP, consistent with the case study literature. We also find, however, that connection rates similarly improved in the control regions...

From 1994 onward, Bolivia undertook a major reform of its infrastructure sectors. The authors examine the impact of the reforms from the perspective of poor households in the adjacent cities of La Paz and El Alto, particularly in terms of access to services. Different policies adopted across the infrastructure sectors led to diverging outcomes. In the water and sewerage sector, the concessionaire was placed under legal obligation to meet connection targets in low income neighborhoods, while customers were given the facility to spread payment of connection charges over a two year period and opt for a lower cost "condominial connection." As a result the rate of expansion of services increased by 70 percent relative to the pre-reform period. In the telecommunications sector, fixed and cellular services tell very different stories. On the one hand, fixed line services remained inaccessible to the poor due to the membership fee of US$1,500 charged by the cooperative, or the alternative nonmember option of paying a US$23 monthly rental fee. On the other hand...

Using a city-level database of global Urban Indicators, the author finds that: 1) Improved access to urban potable water and sewerage connections is consistently associated with low child mortality. 2) Government involvement in providing water services, especially locally, significantly reduces child mortality. 3) Private or parastatal participation in providing sewerage connections is associated with low child mortality. $) Rapid urban growth and high levels of poverty within the city are correlated with high child mortality.

This report presents the main results from cost models that were developed as an input to the High Powered Expert Committee on Urban Development in order to estimate the investment, operations, and maintenance requirements for urban water, sanitation and municipal solid waste in India. The cost models are designed as tools that allow linking the various building blocks of the cost estimation to one another, and tests the impact of the main model assumptions on the overall investment requirements. A cross-country comparison is also conducted to benchmark the key service standards adopted in the models against international experience. The report addresses the challenge of India's fast growing urban population and the high backlog in urban service delivery. Infrastructure deficits in urban areas are large and growing. Universal water access for urban population in India has yet to be realized. The report uses the cost models to discuss India's municipal financing needs, urban water supply services, urban sewerage services...

Before the Gulf wars, Baghdad had a well-functioning water and sewerage system, with standards of reliability, access, and quality similar to many first world countries, illustrated by a coverage of 95 percent in urban areas and 75 percent in rural areas in the 1990s. Because of the war, economic sanctions, and the deteriorating security situation, the national drinking water coverage was down to 48 percent by 2005. Based on an analysis of the issues, the Mayoralty of Baghdad (MoB) adopted the leadership for results (L4R) approach following contacts with the World Bank team in November 2012. The project "Improving Water and Sewerage Management in Baghdad", supports a change management process in addition to technical infrastructure improvements, and contributes to achieving the government's ambitious goal of serving all citizens of Baghdad with reliable water and sewerage services by 2017 and as outlined in the objectives of the National Development Plan (NDP) 2013-2017. The L4R is about changing behaviors (without large upfront investments) to better serve customers. The L4R and rapid results initiative (RRI) demonstrated that an enabling environment established through leadership...

O objetivo deste trabalho é estudar as tubagens de polímeros aplicadas nas redes prediais de águas e esgotos. A utilização deste tipo de material tem vindo a aumentar, mas o conhecimento por parte de projetistas e instaladores não tem vindo a acompanhar o ritmo de crescimento. Esta análise irá permitir um maior conhecimento dos materiais disponíveis e das suas caraterísticas próprias, o que induz a uma escolha acertada e a uma instalação adequada. No início do trabalho clarificou-se o significado e a origem dos polímeros, contando a sua história. Visitou-se a fábrica de tubos Fopil para pesquisar o processamento de polímeros. Explicou-se o fabrico de polímeros, que varia de acordo com as propriedades e aplicações desejadas. Os tubos poliméricos disponíveis no mercado para abastecimento de águas e esgotos foram analisados em relação às suas caraterísticas, vantagens e desvantagens e ligações disponíveis. Existem cuidados a ter no transporte, armazenamento e manuseamento dos tubos. Após a análise das caraterísticas técnicas, fez-se o estudo económico para os tubos existentes no mercado. Para isso foi considerado o abastecimento a um edifício multifamiliar com seis apartamentos. O projetista deve estar sempre informado...

The poor productivity in the water and sewerage services (WSS) has been a justification for the difficulties these entities face when trying to expand the service coverage, enhance the quality of service and reduce the cost of service. Improving the WSS productivity is, therefore, one of the best ways of protecting the customer's interests. This article presents an empirical study that computes the total factor productivity (TFP). It stresses the results obtained and discusses them, proving the low productivity of this sector in Portugal and pointing to the conclusion that the private and the rural WSS are the most productive ones.

Many studies of the water and sewerage industries place significant importance on the benefits of economies of scale and scope and how these relate to vertically integrated firms. We have re-examined the early literature on scale and scope economies and find that these studies do not implicitly preclude non-integrated firms from fully utilising assets for multi-product activities; they can still reap scope economies through trading in the open market. Further, we demonstrate difficulties in separating these two types of economies when assessing firm performance. Trade-offs between governance and production costs are a key issue in determining the value of vertically integrated firms that may undergo divestiture. We discuss the present policy debate regarding the optimal structure of the water and sewerage markets in England and Wales in the light of this, and recommend avenues of research that will help determine the optimal policy.
