Mobile Application

3Rwater’s Follow the Drop mobile app and data platform helps property owners equitably gain access to green stormwater infrastructure (GSI) solutions to mitigate stormwater runoff, as well as supports municipalities with data and GSI asset management. As an easy-to-use community engagement tool, the app uses existing rainfall sensor networks and impervious cover data to calculate how much stormwater a property is generating. It then provides optimum sizes and types of GSI solutions using professional design standards for property owners to select from and submit to the stormwater agency for a potential fee credit, rebate, or grant where offered.  The data management allows both the municipality and user to track the status of their projects, volumes of stormwater captured and ongoing credits allocated/money-saved. 


The software is customizable to match local municipal GSI programs and supports municipal GSI planning, asset management, collecting stormwater metrics, as well as community engagement and outreach to promote GSI and/or incentive programs.  It also helps cities that are transitioning to smart, sustainable infrastructure that need tools to engage the public and stormwater metrics for tracking milestones.

Educating the community on methods of climate adaptation is an important step to build resilient communities. The Follow the Drop mobile application supports educational outreach programs for property owners to reduce stormwater runoff and build water security.  For schools, 3Rwater also developed the Follow the Drop design-thinking curriculum to engage and empower the youth to take part in building climate resiliency. See our Follow the Drop  Curriculum.


Follow the Drop Curriculum

The Follow the Drop curriculum was created to teach students about the design-thinking process and use critical thinking skills to identify solutions to stormwater management. Developed by professionals in the field of green infrastructure, the curriculum offers real-world examples of current water issues and techniques to build resiliency. The curriculum has been designed to meet a variety of educational standards, including Next Generation Science Standards (NGSS), International Technology and Engineering Educators Association (ITEEA) Standards, and Common Core Math (CCSS.MATH.CONTENT). It includes 13 lessons and culminates with student-led green infrastructure projects to address stormwater management on campus.

The Follow the Drop Curriculum can be used to support cities’ stormwater education programs and community engagement using the Follow the Drop mobile app. It can allow students to be engaged in the design-thinking process while also identifying opportunities to capture stormwater runoff on their campuses and in their communities.
