  • A basic bottom-up approach for small systems of safe-water supply: a decentralized case study in Uganda

    In developing countries, diarrhea is known as the major cause of burden among children. Diarrhea is associated to poor quality of drinking water, inadequate sanitation and insufficient hygiene behavior. This work introduces a bottom-up approach for the implementation of a borehole installation in conjunction with proper water handling in rural areas. A pre-intervention survey was performed as a ...

  • Horizontal Wells - Technology Overview

    Horizontal well technology has been incorporated into many current environmental remediation applications (and associated contaminants), such as in situ bioremediation, air sparging, vacuum extraction, soil flushing, free product recovery, etc. Ac cording to information reviewed, this technology is most applicable to sites with relatively shallow soil and/or groundwater contamination, and can ...

  • Controlling weather extremes – turning rainfall to an advantage

    Shropshire and the surrounding areas are well known to experience seasonal flooding, according to the Shropshire Star. Whilst wet ground conditions can be a burden, triggering increased costs, lower output and extra work, the advantages of rainfall certainly outweigh the opposite extreme of the weather spectrum. Shaun Jones, rural professional director of Halls, Shrewsbury, explained that ...
