Is rainwater harvesting legal in Texas?
Yes! Rainwater harvesting is not only legal — it’s encouraged. Texas law protects the right to collect rainwater and even offers incentives in some municipalities.
What can I use rainwater for?
Rainwater can be used for:
- Landscape irrigation
- Toilet flushing
- Laundry
- Whole-house potable use (with proper filtration)
We’ll design your system to match your needs and local code requirements.
How much rainwater can I collect?
On average, you can collect about 0.6 gallons per square foot of roof per inch of rain.
Example: A 2,000 sq ft roof in a 1” rainstorm yields roughly 1,200 gallons.
Do I need a permit to install a rainwater system?
Depending on the system type and your location, permits may be required. We handle all permitting and ensure your system is code-compliant from day one.
Can I drink rainwater?
Yes — if the system is properly designed for potable use. This includes multi-stage filtration, UV or chemical disinfection, and proper plumbing. We specialize in safe, code-compliant potable systems.
How much does a rainwater system cost?
System pricing depends on tank size, components, and intended use.
- Non-potable systems typically start at a few thousand dollars
- Potable systems for full-home use can run $30,000 and up
We provide a customized quote after your free consultation.
What size tank do I need?
It depends on your water usage, goals, and local rainfall. We’ll size your tank based on:
- Roof collection potential
- Average rainfall
- How much of your water you want to offset
What kind of maintenance does the system need?
Most systems need basic upkeep 2-3 times per year:
- Gutter and screen cleaning
- Filter inspection
- Pump checks
Potable systems need more regular service — we offer plans for that.
Do you offer maintenance or service plans?
Yes. We offer tailored service plans for non-potable and potable systems, including seasonal checkups, water testing, and filter replacements.
