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.
