This year’s AFL Grand Final has been linked to some unique water usage patterns. 

Collingwood's nail-biting four-point victory over Brisbane during Saturday's AFL Grand Final had the nation gripped with excitement. 

Amid the thrilling clash of top teams, Melbourne Water observed water usage trends.

The study uncovered an intriguing link between crowd behaviour and water consumption during this high-profile matchup.

Dubbed the “Flush Factor” by Melbourne Water, the investigation found a noticeable surge in toilet flushes during halftime, quarter breaks, and after each goal or behind was scored when compared to the same time on the previous day.

Still, Collingwood's spectacular win fell short of eclipsing the unforgettable 2010 showdown against St Kilda (draw) when water usage peaked at 50.8 per cent above average after the final siren.

Despite not matching that record, Collingwood's victory on Saturday still elicited a significant increase in toilet water usage, at 27.6 per cent. 

Their performance on the field, marked by dedication, skill, and strategic plays, secured a well-deserved win over Brisbane.

Dave White, Melbourne Water's Water Operations Centre Lead, says the Flush Factor introduces a new dimension to the AFL Grand Final by spotlighting the influence of collective behaviour on water demand.

With millions of passionate fans either glued to screens or in attendance, the flush factor underscores how minor individual actions can accumulate into substantial water usage on a larger scale.

Melbourne Water encourages all spectators and viewers to be mindful of their water consumption as warmer months approach. 

By adopting straightforward water-saving habits, such as using water-efficient toilets and reducing water usage, individuals can contribute to sustainable water management and conservation efforts.

Mr White stressed the importance of creating awareness about the flush factor during major sporting events. 

“By highlighting the impact of collective behaviour on water usage, we hope to encourage fans to make conscious choices and contribute towards a more sustainable future,” he said.
