  • Water quality perceptions and willingness to pay for clean water in peri-urban Cambodian communities

    This paper studies household demand for improved water quality in peri-urban Cambodia, with particular attention paid to the influence of water quality on willingness to pay (WTP). Utilizing data from 915 household surveys, we analyze responses to a contingent valuation scenario using multivariate logit regression techniques that account for subjective perceptions of water quality. We estimate a ...

  • Urban environment — SOER 2010 thematic assessment

    Urban areas and quality of life For the three-quarters of Europe’s population that lives in cities and towns, a good urban environment is a precondition for a good quality of life. It seems, in part, that over the last decade, attitudes to living in cities have been changing. People are no longer moving away from cities (or have returned to them), residential sprawl has slowed and, in a ...

  • Electronic Waste: The Rich Resource in the Urban Mine

    Forgetting your mobile phone can be a real pain, playing on your mind during the day. Then as you think you can feel your phone vibrating in your pocket and you come to realise how dependent we are on our gadgets. Electrical equipment has changed our lives completely and we rely on phones, microwaves, TVs, kettles, computers to keep us informed, entertained and even alive. It is hard to imagine ...

  • Indestructible Pumps for Clean Water

    Sulzer pumps are used in the production of drinking water in many cities around the world. The special qualities that these pumps possess can be seen at the Zurich Municipal Water Utility. There, the operators have to cope with rising land and energy prices and a challenging topography. A small water flea plays a major role in Zurich. It swims around in a container of drinking water with some of ...

  • The natural way to clean wastewater

    John Todd founded Ocean Arks International in the 1980s, where he started to experiment with processes that mimic natural ways to purify wastewater. He built a greenhouse and ran sewage through a series of tanks, with plants suspended in the flowing waters, and constructed marshes made of sand and gravel. No chemicals were added, but plenty of aquatic creatures from snails to small fish were ...

  • Removal of Fallen Leaves Can Improve Urban Water Quality

    The timely removal of leaf litter can reduce harmful phosphorus concentrations in stormwater by over 80 percent in Madison, Wisconsin, according to a recent U.S. Geological Survey study. Autumn leaf litter contributes a significant amount of phosphorus to urban stormwater, which then runs off into waterways and lakes. Excessive amounts of ...

  • Climate adaptive urban planning and design with water in Dutch polders

    The existing water management in Dutch polders is based on independent water systems for each polder. These are featuring artificial stabilized ground and surface water levels. As a result of the local climate the water levels in the polders are not continuously at a constant level. To maintain a stable water table in the polders, the surplus of relatively clean rainwater has to be pumped away ...
