  • European waters - current status and future challenges - a synthesis

    The Europe 2020 strategy is the European Union's strategy for economic growth in Europe over the next decade. This strategy envisages the development of a 'greener', more environmentally friendly economy in Europe. Sustainable water management is a critical element of this green economy because healthy and resilient ecosystems provide the services needed to sustain human well‑being and our ...

  • Current and Future Wastewater Reuse in Texas

    ABSTRACTThe reuse of treated wastewater effluent has served as a source of water supply in Texas for decades. While this has often occurred without detailed planning, the formal, planned reuse of treated wastewater effluent is increasing rapidly in the state, especially in the area around the Dallas-Fort Worth metroplex. To plan for the increased water demand, Texas has been divided into 16 ...

  • Advances and current changes in cellular telemetry

    Recent advances in cellular technology are offering more efficient and reliable wireless transmission of data between remote locations and the central collection points.Wireless telephone technology has been around in various forms since the 1940’s. Stevens was the first company to introduce telephone telemetry technology for remote water monitoring with the Telemark in 1939. In 1969, Bell ...

  • Current status, problems and control strategies of water resources pollution in China

    The surface water of 10 major river systems across China has been under intermediate pollution with striking eutrophication problems in major lakes (reservoirs). More data from the Ministry of Environmental Protection of China showed that underground water in 57% of monitoring sites across Chinese cities was polluted or extremely polluted. Rural water pollution, the rising number of ...

  • Analysis of the current knowledge gaps in the implementation of the Water Framework Directive

    The general objective of the REBECCA project1 is to provide relevant scientific support for the implementation of the Water Framework Directive (WFD). The two specific aims of the project are, firstly, to establish links between ecological status of surface waters and physico-chemical quality elements and pressures from different sources, and, secondly, to develop and validate tools that member ...


  • Water infrastructure security against the current terror threat in the United States

    On May 2, 2011, the United States (U.S.) President Barack Obama announced that the U.S. forces killed Osama Bin Laden, the world's most dangerous terrorist leader that killed approximately 3000 Americans on September 11, 2011 (9/11) terror attacks.  Currently, the U.S. intelligence is in possession of valuable materials of Al Qaeda operations (Thomas, 2011).  Terrorist attack plots ...

  • Prediction of water and wastewater networks rehabilitation based current age and material distribution

    Ageing drinking water, stormwater and sewer pipe networks imply an increased degree of rehabilitation. The need for rehabilitation can be predicted using lifetime distribution functions together with current network age and material distribution. In Sweden, current age and material distribution is neither documented on a national level, nor for many water utilities on a local level. In this ...

  • Effect of alternating and direct current in an electrocoagulation process on the removal of cadmium from water

    The main objective of this study was to investigate the effects of AC and DC on the removal of cadmium from water using iron as anode and cathode. The various operating parameters on the removal efficiency of cadmium were investigated. The results showed that the optimum removal efficiency of 98.1 and 97.3% with the energy consumption of 0.734 and 1.413 kWh/kL was achieved at a current density of ...

  • Decentralised systems – definition and drivers in the current context

    This paper explores the current context for decentralised approaches in the provision of urban water services. It examines the recent history of decentralised systems' implementation in Australia and identifies its drivers. The drivers included addressing capacity constraints of centralised systems, mitigating the environmental impact of urban development, and increasing the resilience of ...

  • Alternative microbial indicators of faecal pollution: current perspective

    During the early history of various countries, epidemics of diseases such as typhoid, shigellosis, cholera and amoebiasis were common threats. It was subsequently determined that the primary source of these pathogens was sewage. The environmental bodies receives a significant amount of treated, partially treated or untreated sewage, which severely depletes the water quality of these water bodies ...

  • Current pollution status of Yangtze River and controlling measures

    The concentration of Persistent Organic Pollutants in Yangtze River in China is increasing steadily, especially in the downstream, where the drainage is often discharged into the water body without any treatment. In this study, the pollution status, trend of mainstream and Three Gorges area are analysed based on the statistical data of the water quality in the past years. Results indicate that ...
