  • 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 ...

  • Improved estimate of multiyear drought for water resources management studies

    Using short hydrological records to characterise extreme drought for water studies could lead to uncertain results. At first, this article introduces a generic model that extends the length of short hydrological records to improve the analysis of drought. Using simulated data, the extension model performance was tested and found to work well and later the model was used to extend the annual ...
