  • Challenges of public water provision in Nigerian cities: a review

    In spite of the importance of adequate water quality and quantity for human health and survival, public water supply coverage in Nigerian cities appears to be decreasing and deteriorating. Hence, this study was designed to assess the challenges of public water provision in Nigerian cities. Some of the reasons for this deterioration include: inadequate water supply policy, lack of autonomy for ...

  • Performance-Based Specification Of Electrical Leak Location Surveys For Geomembrane Liners

    ABSTRACT Electrical leak location surveys can be a crucial part of the final quality control of geomembrane liner installations. The method has been offered as a commercial service since 1985 and is the only practical test method that can find holes in the liner after protective soil cover is put on the liner. During the past fourteen years the test method has been used on a wide variety of ...

  • Electrical Leak Location Arc Tester to Revolutionize Liner Quality

    New equipment has been developed that behaves like a spark tester, but doesn’t have to be performed on conductive-backed geomembrane.  It has the same requirements as the water puddle and water lance methods in terms of a conductive layer underlying the geomembrane, including soil.  It is not a spark tester, which is used exclusively on conductive-backed geomembrane; yet, it ...

  • Experience with GCLs used as a conductive layer in geomembrane leak-location surveys

    Engineers, installers, regulators, and owners are starting to rely on geomembrane leak-location surveys as part of the construction quality assurance for landfills. The various methods are described in ASTM Standard D 6747.' Standard procedures for conducting leak-location surveys of geomembranes covered with earth materials are described in ASTM Standard D 7007.2 Figure 1 shows the ...
