About this project

We’re building data-driven tools for realistic system sizing and seasonal performance across Texas. The goal is to make rainwater harvesting approachable and easy to evaluate for homeowners, designers, and policymakers. Created by a hydrogeologist who lives in Texas, this project is built to be transparent, practical, and improved over time with input from the community.

Ways to get involved

Collaborate

Developers, data folks, educators: let’s improve the model and UI together.

Feedback

Tell us what’s confusing, what’s missing, or what worked great.

Sponsorship

Support ongoing hosting and improvements; be recognized as a sponsor.

Local resources

Know a great installer, city rebate, county program, or local resource we should list? Send recommendations so Texans can find help in their area.

Roadmap & Funding Priorities

The next development phase will enhance the simulation engine to support user-defined monthly demand and refined system parameters. Instead of applying an average consumption rate, users will be able to model seasonal variability such as irrigation demand, agricultural cycles, or occupancy changes. This improves the mass-balance relationship between rainfall, storage, and withdrawals, resulting in more accurate sizing recommendations and reliability analysis.
