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.

Roadmap & Funding Priorities

Today, the calculator uses monthly rainfall aggregates. The next major upgrade is daily precipitation by ~2sq mile grid cell to deliver higher‑fidelity sizing and validation. Hosting daily data at statewide scale requires meaningful storage and compute power, additional sponsorship will make this possible.

Roadmap

  1. Daily grid rainfall
  2. Enhanced simulations
  3. Air quality overlays
  4. Temperature data
  5. Soil & infiltration
