The city of Townsville in northern Queensland, has endured a variety of extreme weather events in recent years from flooding and cyclones to extreme temperatures and drought. All of these issues have stretched the capacity of an already limited water supply system that continues to see the effects of climate change, as are many urban areas throughout the world. Australia’s climate continues to be hotter and dryer, placing an increased focus on water security issues. In addition to these supply factors, demand for water continues to climb, particularly for Townsville. These deficits in water supply require a renewed focus on water modelling to ensure that policies adopted to address water security are appropriately targeted to ensure sustainable urban development.

This research project seeks to contribute to this challenge by providing a water modelling study for Townsville out to 2030. In doing so, it seeks to understand the key variables affecting both demand and supply and provide nine scenarios to forecast potential water security within the city. AWBM was utilised to generate run off data and an excel water balance model was constructed to achieve this. Drawing on existing studies of the Townsville area and wider Australia, the study will also provide a contextual understanding of the issues affecting the city.

The study ultimately concludes that Townsville will require long-term investments in supply initiatives while simultaneously incorporating permanent water restrictions to mitigate the projected water deficits facing the city. The planned investment in the Haughton Pipeline duplication was found to be necessary to sustain Townsville’s projected growth. Permanent water restrictions to reduce consumption by 30% was also found to be the most optimal water management measure to reduce consumption to an average of 0.32kl p/p, p/day.
