The past decades have seen planning and implementation of built infrastructure in all over the developed and developing world growing in large scales. This has been influenced by economic and population growths, urbanization and industrialization, which in turn have put increasing stress in provision of services. The paper reviews the policy dimensions of water infrastructure development and financing in the two largest economies at present, China and India, including planning, implementation and decision-making processes. Findings indicate that main challenges for infrastructure development have been limited sources of financing, but also policies and their implementation. The high levels of investment in water infrastructure in the two countries have been impressive, mainly in China. However, they still have not necessarily addressed efficiency over the long term, supported more inclusive and higher economic growth or improve social and environmental conditions in all cases. © 2016

One development can be predicted with complete certainty; the world in 2030 will be significantly different from what it is in 2010. Water governance, which is a broad concept, must also adopt to these changes. While there are no usable indicators for water governance that exist at present, some general indicators for governance of individual countries are available. These are of limited value for the water profession. It is argued that at least 10 to 12 good, independent and objective case studies of good water governance would be very useful to learn what were the enabling environment and critical factors that contributed to their success and could allow others to significantly improve their current practices and processes. © 2010 Taylor & Francis.

During the 1980s, after years of centralized management and a culture of inefficiency and corruption, the Phnom Penh Water Supply Authority (PPWSA) was dysfunctional. Unaccounted for water routinely surpassed 70%. During the 15-year timeframe between 1993 and 2008, it experienced a metamorphosis; with enlightened management and dedicated and competent staff, the Authority has been completely turned around. Its annual water production increased by 437%, the distribution network by 557%, pressure of the system by 1260%, and its customer base by 662%. Unaccounted for water was reduced from 72% to 6.19%. Its profit increased consistently as has the amount of taxes paid to the Cambodian Government. This paper is a summary of an independent evaluation that examines how this remarkable transformation has been achieved. © 2010 Taylor and Francis. © 2010 Taylor & Francis.

This paper seeks to contribute to the current debate about public versus private management of urban water supply services. The main purpose of urban water supply is to ensure the provision of a sufficient quantity of good quality water to users. This article examines water quality by using a subjective indicator: user satisfaction with tap water quality. The goal of the paper is to determine whether users perceive a difference in tap water quality supplied by public operators on the one hand, and by private-sector operators on the other. Data is sourced from a survey carried out in 64 Spanish cities. A number of different subjective determinants of water quality have been considered: the socio-economic characteristics of those surveyed, objective indicators of water quality, as well as environmental and economic factors of urban water services. Data analysis, using an ordered logit regression model, shows that when urban water services are in the hands of a private company, the quality of the tap water, as perceived by users, deteriorates. © 2015, Springer Science+Business Media Dordrecht.
