This paper is a study on financial sustainability of water supply service to the city of Offa, in Kwara State, Nigeria. The value consumers place on water supply and the willingness-to-pay (WTP) for improved service and the factors that influence their preferences were determined using an econometric model. The WTP was estimated using a double-bounded dichotomous model and the mean WTP was found to be 70% higher than the current tariff, while the expected monthly revenue from domestic customers alone was 21 million ($175,000)1. The study revealed that the consumers were not satisfied with the level of service but they were willing to pay for improved service and even support reforms that will bring about this change. The mean WTP in practical terms gives social benefit of a policy for the offered service for the affected population. The study outcome shows that the high WTP is a good incentive for private sector involvement in the management of urban water supply.

In this study the contingent valuation method is applied in order to estimate the willingness to pay (WTP) of the inhabitants of Sucre (Bolivia) for an improvement in the urban water supply system. The study finds that about 55 per cent of households would be willing to pay an increase in their water bill for an improvement in the service. In order to deal with the problem of protest responses and the possible presence of a sample selection bias, a Heckman two-step model was estimated. More specifically, the econometric analysis undertaken reveals that there is no evidence of sample selection bias and that WTP positively relates to the respondents' household income, their level of education, the continuity of the water supply service, and the fact of being forced to carry water to cover their basic needs of drinking, cooking and hygiene.

Abstract. Combining historical climatology and environmental history, this article examines the diverse range of strategies deployed by the city government of Barcelona (Catalonia, NE Spain) to confront the recurrent drought episodes experienced between 1626 and 1650. Our reconstruction of drought in Barcelona for the period 1525–1821, based on pro pluvia rogations as documentary proxy data, identifies the years 1626–1635 and the 1640s as the most significant drought events of the series (highest drought frequency weighted index and drought duration index). We then focus on the period 1601–1650, providing a timeline that visualises rain rogation levels in Barcelona at a monthly resolution. Against this backdrop, we examine institutional responses to drought and discuss how water scarcity was perceived and confronted by Barcelona city authorities. Among the several measures implemented, we present the ambitious water supply projects launched by the city government, together with the construction of windmills as an alternative to watermills, as a diversification strategy aimed at coping better with diminishing water flows. We pay special attention to the institutional efforts to codify the knowledge about Barcelona's water supply, which in 1650 resulted in the Book of Fountains of the City of Barcelona (Llibre de les Fonts de la Ciutat de Barcelona). This manual of urban water supply, written by the city water officer after 3 decades of experience in his post, constitutes a rare and valuable source to study water management history but also includes significant information to interpret historical climate. We analyse the production of this manual in the context of 3 decades marked by recurrent episodes of severe drought. We interpret the city government aspiration to codify knowledge about urban water supply as an attempt to systematise and store historical information on infrastructure to improve institutional capacities to cope with future water scarcities.

Groundwater is an excellent alternative to meet public water supply demands, especially in the face of the water crisis and pollution of surface water bodies. Many municipalities throughout the national territory use water from springs for urban water supply. Barra Mansa, a city located in the southern Fluminense region, is an example of this. The aim of this study was to evaluate the water quality of three springs located in the city of Barra Mansa, in order to verify its water potential. The results obtained showed the water potential of the Municipality, revealing, however, the state of degradation and the risk of contamination of groundwater, imposing the need to develop measures to preserve, prevent and mitigate anthropic impacts on the water sources. In this way, the questions proposed here may contribute to a reflection about the exploration of the sources and the implications inherent to its use.

The provision of safe and universal water supply in an equitable and efficient manner is extremely important for urban water reform programs currently being carried out in developing countries. The sector reform not only requires a significant amount of working capital, but also people's willingness to pay for the improved infrastructure. This paper serves two purposes – first, it explains the meaning of ‘full-cost of water services’ in urban areas and attempts to provide a framework to value economic and environmental externalities for the urban water supply and use through a case study of India's capital city – Delhi. The second part uses contingent valuation method to establish people's willingness to pay from a survey of 1,100 households for water supply with better quality and reliability. Policy implications are subsequently discussed, keeping in mind cost of provision of water supplies. Also included is the assessment of the cost of unreliable supply (coping cost), which otherwise households are spending in the absence of a reliable supply. The paper shows several instances of reciprocal externality wherein the residents themselves absorb the cost of over-extraction, in terms of declining water tables, and cost of salinity in terms of decentralised treatment cost.
