  • `Standards are desperately needed for plastic and pesticide contamination in soil´

    In addition to plastic in the oceans, plastic contamination in arable land throughout Europe and other parts of the world is a growing problem. No standards exist for these types of soil pollutants, nor for pesticide residues or their degradation products. For this reason, Professor Violette Geissen is calling for standards to be implemented. On 15 June, Geissen will deliver her inaugural address ...

  • Intelligent pressure management reduces water losses and minimizes pipe brakes

    Leaks in water pipes and leaking valves in urban water distribution systems and pipeline networks, mainly in developing and threshold countries, are the reason for water losses of up to 50 percent in relation to the water quantity being produced in the water works. The articele of the 'Industrial Valves 2009' presents an effective pressure management on the basis of an intelligent control ...

  • Using performance indicators as a water loss management tool in developing countries

    Water utilities in developing countries are facing the challenges of substantial water losses in their water supply systems.

  • Tackling water losses through improved domestic water bills

    The domestic water bills that municipalities send out to consumers on a monthly basis are a key interface between local government and citizens. Being a legal instrument, as well as a communication medium, the consumers' level of understanding of their water bills and the confidence in the information provided is therefore indicative of their effectiveness. A lack of understanding of bills ...

  • Metropolitana milanese reduces water loss on critical steel pipeline

    Assessing the condition of buried water infrastructure can yield a variety of outcomes that are difficult to predict. Sometimes, they even seem random. The common belief that the age of a pipe determines its condition is rarely correct – in many cases, a newer main can be in worse condition than one twice or three times as old. Instead, operational, environmental and installation factors ...
