Abstract Water supply in the world is dependant primarily on rainfall and therefore, is significantly dependant on climatic variability and change. Coupled with reduced rainfall reliability, demographic factors, and cyclical economic growth and recession, increasing competition for water resources augment concerns over existing water resources and impose a strain on future water security. Hence, most water utilities are implementing water demand reduction strategies: in Australia’s Northern Territory, Power and Water Corporation (the monopoly water and sewerage utility) have implemented the “Living Water Smart” programme with the aim of reducing water consumption.

“Living Water Smart” is a five-year water-efficiency programme running from 1 June 2011 to 31 May 2017, implemented by Power and Water Corporation in the greater Darwin area that aims to reduce consumption by 10 GL over this period. The programme focuses on behaviour change and developing legacy outcomes to maintain these water efficiency savings into the future.

The aim of this thesis is to investigate the efficacy of “Living Water Smart” in terms of reducing water consumption in the past five financial years (2011/2012 to 2015/2016). The interdependencies of water consumption trends in the greater Darwin area and meteorological and climatic factors are investigated. The billed consumption for every metered point of supply over a five year period is averaged to give a time-sequential average for overall water consumption in the area of interest: the trend is then analysed to ascertain the extent to which demand reduction measures have been effective after considering other factors such as climate, population change, increased land development, and metering errors.
