Water Conservation App | Save Water at Home
- A smartphone app providing real-time feedback on water consumption can significantly reduce household water use, according to a study led by the University of California, Riverside.
- The study, spearheaded by Mehdi Nemati, assistant professor of public policy at UCR, focused on the Dropcountr app.
- Dropcountr leverages data from smart water meters, translating it into actionable insights for users.
A groundbreaking study spotlights how a smartphone app, such as Dropcountr, is cutting down household water usage, presenting a cost-effective solution for water conservation. The findings, detailed in the Resource and Energy Economics journal, reveal an average 6% reduction in water use among app users, with high-volume users achieving up to a 12% decrease. Real-time feedback and leak alerts are key components, empowering users to make informed decisions, and meet the conservation goals. This innovative tool, highlighted by News Directory 3, also assists California water agencies in achieving state-mandated targets, and it’s not just about immediate savings – the study shows lasting water-saving behaviors.

Smartphone App Cuts Household Water Use, Aids Conservation Goals
Updated may 28, 2025
A smartphone app providing real-time feedback on water consumption can significantly reduce household water use, according to a study led by the University of California, Riverside. The research highlights the potential of such tools to help California water agencies achieve state-mandated conservation targets.
The study, spearheaded by Mehdi Nemati, assistant professor of public policy at UCR, focused on the Dropcountr app. Findings indicated an average 6% reduction in household water use among app users, with even greater savings observed among the highest water consumers. This digital feedback offers a “nudge” to encourage water-saving behaviors.
Dropcountr leverages data from smart water meters, translating it into actionable insights for users. The app displays water usage, compares it to similar households, and tracks changes over time. It also alerts users to potential leaks and when consumption approaches higher-rate tiers. Water utilities can use the app to share conservation tips and data on rebate programs for drought-tolerant landscaping.
“California water agencies are under pressure to hit individualized water-use targets and conservation goals,” Nemati said. ”Our study shows that this digital feedback tool can be a powerful, low-cost way to help households manage their use and reduce consumption.”
The research centered on the City of Folsom, CA, where Dropcountr was introduced to residential customers in late 2014. Data from approximately 3,600 households, collected between 2013 and 2019, provided over 32 million daily water use records for analysis.
Published in the journal Resource and energy Economics, the study revealed that participating households decreased daily consumption by an average of 6.2% compared to a control group. The top 20% of water users achieved reductions of up to 12%.
“This is a crucial outcome when every drop counts,” Nemati said. “We found strong, statistically significant reductions, especially for high-use customers.”
the app’s effectiveness also stems from incorporating behavioral science principles. Users receive personalized summaries comparing their water use to efficient neighbors, promoting realistic conservation goals.Leak detection, based on continuous usage patterns, proved notably effective. Water use dropped roughly 50% the day after a leak alert, followed by a 30% drop the next day, and a sustained 9% reduction even six days later.
“The sharp drop suggests customers are paying attention and acting quickly,” Nemati said. “One major advantage is that they can detect leaks right away — sometimes before they cause damage or result in costly bills.”
Nemati also noted the lasting impact of these behavioral changes.”We looked at water use 50 months out and still found sustained reductions,” he said. “People weren’t just reacting once and forgetting. They stayed engaged.”
While Dropcountr is most effective with smart meters, many California homes still rely on older systems. Though,the adoption of advanced metering infrastructure is expanding.
Nemati emphasized that many agencies with smart meters still use traditional methods,such as mailed letters,to notify customers of high usage or leaks.
“People get water bills,but the information may not be salient,” Nemati said. “What platforms like Dropcountr do well is make the data meaningful. People want to use water wisely. They just need timely,clear,and actionable feedback.these platforms give them that — and they work.”
What’s next
As California prepares to enforce stricter drought and efficiency standards, Nemati suggests that more utilities should consider implementing digital tools like Dropcountr to promote water conservation and ease pressure on water systems.
