Cities worldwide are experiencing the failures of water privatisation. Unequal access, broken promises, environmental hazards and scandalous profit margins are prompting municipalities to take back control of this essential service. Water ‘remunicipalisation’ is a new, exciting trend that this book explores at length. Case studies analyse the transition from private to public water provision in Paris, Dar es Salaam, Buenos Aires and Hamilton, as well as look at a national level experiment in Malaysia. The journey toward better public water illustrates the benefits and challenges of municipal ownership, while at the same time underlining the stranglehold of international financial institutions and the legacies of corporate control.

The circulation of water in nature takes place through the large and small water cycles. Humanity, through its activities and systematic transformation of natural land into cultured land, accelerates the runoff of rainwater from land. Limiting evaporation and the infiltration of water into the soil decreases the supply of water to the small water cycle. The equilibrium of the water balance in the small water cycle is thus disturbed and it gradually starts to break down over land.
If there is insufficient water in the soil, on its surface and in plants, immense flows of solar energy cannot be transformed into the latent heat of water evaporation but are instead changed into sensible heat. The surface of the ground soon overheats, and as a result, a breakdown in the supply of water from the large water cycle arises over the affected land. Local processes over huge areas inhabited and exploited by human beings are changed into global processes and with processes that occur without the assistance of human beings; together they create the phenomenon known as global climate change. The part of global climate change caused by human activities then is largely based on the drainage of water from the land, the consequent rise in temperature differences triggering off mechanisms which cause a rise in climatic extremes. The disruption of the small water cycle is accompanied by growing extremes in the weather, a gradual drop in groundwater reserves, more frequent flooding, longer periods of drought and an increase in the water shortage in the region.
