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.

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.

Paper describes and analyses new and innovative concept for possible integration of solar photovoltaic (PV) energy in urban water supply system (UWSS). Proposed system consists of PV generator and invertor, pump station and water reservoir. System is sized in such a manner that every his part is sized separately and after this integrated into a whole. This integration is desirable for several reasons, where the most important is the achievement of the objectives of sustainable living in urban areas i.e. achieving of sustainable urban water supply system. The biggest technological challenge associated with the use of solar, wind and other intermittent renewable energy sources RES is the realization of economically and environmentally friendly electric energy storage (EES). The paper elaborates the use of water reservoires in UWSS as EES. The proposed solution is still more expensive than the traditional and is economically acceptable today in the cases of isolated urban water system and special situations. Wider application will depend on the future trends of energy prices, construction costs of PV generators and needs for CO2 reduction by urban water infrastructure.
