We’ve always said that small changes lead to a massive impact, and now we have the data to prove it. The University of Queensland recently analyzed over 9,218 shower events from our trial with Water Corporation (West Australia's primary water utility), and the results are a behavioural scientist’s dream.
As water utilities across the globe face mounting pressures from climate change and population growth, finding effective, low-cost demand management solutions is more critical than ever. The recent field trial, conducted in partnership with Water Corporation, demonstrates just how powerful targeted behavioral interventions can be. By providing real-time visual feedback to users, this innovative smart-timer achieved a remarkable **2-minute average reduction** in shower durations across the entire fleet of test devices. When scaled to a city the size of Perth, a 2-minute reduction per person could save between **3% and 7% of the total daily water supply, proving that small behavioral shifts can deliver massive systemic benefits.
What makes the ShowerStar solution a truly compelling investment for utility programs is its unmatched effectiveness in targeting high-volume consumers. The field trial data revealed that the top 25% of users—those with an average baseline shower of 16 minutes—slashed their shower times down to 10 minutes, representing a massive **6-minute reduction**. Additionally, the device proved highly effective for customers who identified as only "somewhat motivated" to save water, successfully bridging the gap for demographics that lack the natural initiative to change their habits. For water and energy utilities seeking maximum return on investment, the ShowerStar Shower Sensor Timer & App is not just a conservation gadget; it is a precision tool designed to tackle residential resource waste at its heaviest source.
The value of the ShowerStar Shower Sensor Timer & App extends far beyond simple water conservation; it is a catalyst for major energy and carbon emissions reductions.
Because residential hot water accounts for roughly 40% of household energy consumption, cutting shower times directly impacts the grid. The trial data reveals that a 2-minute reduction in shower time saves between **12 and 25 liters of water** and **0.2 to 0.6 kWh of energy** per shower. Furthermore, this translates to an estimated reduction of **60 to 173 grams of CO2** per shower, seamlessly aligning with utility Net Zero targets while offering tangible cost-of-living relief to customers.
