A Coherent Approach of Statistical Modelling to address the behavioural status of water consumption and available water resources for semi-urban areas in Southeast Asia

This study analysed recent water resources and water consumption datasets from semi-urban towns in the South Asian country
of Sri Lanka. It presents a comprehensive assessment of behavioural status of water consumption over the past 5 years taking
into consideration the impact on rainfall, precipitation patterns and temperature fluctuations. The findings provide important
information on residential demand management and the threshold of consumption by residential users to apply in decision
making process. Furthermore, this information informs policymakers, the water authority, and consumers not only in Sri Lanka,
but across Southeast Asia and globally on critical water infrastructure, sustainable water resources and the applications of water
forecasting for similar developing countries. The present observations contribute to the usefulness of statistical modelling
methods in analysing, interpreting and understanding large datasets around available water resources and water consumption,
providing reliable information to water utilities in reducing a tedious approach of water monitoring and assessment programmes
in the region.
