  • Developing a Culture of “Revulsion”: Singapore Tackles Water Wastage

    Singapore is an interesting place. As a city-state it occupies a very small amount of land area, about 700 square kilometers. Packed into this space are 5.6 million people working in one of the world’s strongest economies. A big part of the economy is based on manufacturing and oil refining. Both of these sectors are intensive water users. Because of this, water availability is a big issue. ...

  • Water Security – A Growing Issue with No Easy Fixes

    The issue of water security – access to enough quality water to make it possible to live safely – is a growing concern for many, just ask the communities of Flint and Corpus Christie. The problem is exacerbated when communities and companies come face-to-face over access to water supplies. Wouldn’t the nice idea be to share?  That’s met with disagreements as ...

  • Study of hydraulics and mixing in roof tanks used in intermittent water supply

    Roof tanks are common in low and middle income countries, due to the intermittent water supply. Their hydraulic and water mixing behaviour has not been studied. This paper presents the results of a study on mixing and water demand in roof tanks, based on physical and numerical models. Tracer tests were carried out on a real scale transparent wall laboratory model of a roof tank, and a ...

  • Investigating the management of unaccounted for water for Lilongwe Water Board, Malawi

    Lilongwe Water Board (LWB) is currently unable to meet Lilongwe City's water demand as evidenced by low supply coverage (65%) and intermittent water supply in the city. One of the major challenges is high levels of unaccounted for water (UFW) reported at 37% (2012), higher than the recommended 23% for developing countries. This study, done in Lilongwe City (Areas 15, 18 and 28), investigated ...
