  • 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 ...

It is the result of a workshop sponsored by the Australian Institute of Public Affairs, a free market-oriented policy think tank, ...


  • A whole-of-the-catchment water accounting framework to facilitate public–private investments: an example from Australia

    Often, information on spatial water use efficiencies in a whole-of-the-catchment context does not exist or does not feed into the water policy process to guide investments. Significant gains in water use efficiency are achievable but the water savings are often assumed rather than identified systematically. This paper used a whole-of-the-catchment water accounting framework to identify the main ...

  • How to Save with Cooling Tower Credits

    Cooling towers dissipate heat from recirculating water used to cool chillers, air conditioners, or other process equipment to the ambient air. Heat is rejected to the environment from cooling towers through the process of evaporation. Therefore, by design, cooling towers use significant amounts of water. The thermal efficiency and longevity of the cooling tower and equipment depend on the proper ...
