Why Texas Property Owners Need Better Water Solutions?
Collecting rainwater should be simple, but most systems aren’t.
Traditional rainwater harvesting systems are often over-engineered, hard to maintain, and prone to water quality issues caused by standing water, complicated first flush setups, and unreliable controls. For property owners, developers, and land managers, that means frustration, wasted water, and systems that never quite work the way they should.
When you add stormwater compliance, fire protection requirements, or limited power access, the problem only gets more complicated.
Why Rainwater Specialists Is Different
We understand the problem because we've designed and installed rainwater collection systems throughout Central Texas for residential and commercial properties.
Through our own hands-on experience with rainwater harvesting systems, Rainwater Specialists developed smarter technology and better system designs that make it easier to collect usable, cleaner water, without constant maintenance.
You can trust us because:
We design, custom-build, and install every system we sell

Flow Boss™, An Automatic First Flush Controller
Our Flow Boss is a proprietary, automatic first flush controller designed to eliminate many of the problems found in traditional rainwater collection systems. Instead of relying on manual or outdated first flush tanks, Flow Boss automatically determines:
How much water should be flushed
When flushing should occur after a rain event
How to prevent standing water in pipes
This converts a traditional wet system into a dry system, automatically, improving water quality and reducing maintenance.
Rainwater Collection Systems Features and Benefits:
- Automatic first flush improves collected water quality
- No standing water in pipes
- Smart monitoring of rain patterns
- Built-in freeze protection for extreme cold weather
- Automatic shutoff prevents accidental tank drainage
- Learns water usage patterns and adapts over time

Frequently Asked Questions
How much does a rainwater collection system cost?
Costs vary based on tank size, system complexity, and site conditions. We provide custom quotes after consultation.
How big are the tanks?
Tank sizes range from 10,000 gallons to 300,000 gallons, depending on your project requirements.
Installation options include above-ground tanks, below-ground tanks, and systems integrated into a home’s concrete foundation.
How much space do I need for an above ground tank?
A typical 30,000-gallon tank that is 7’ 2” high requires a 33 ft. diameter sand pad or 28 ft. concrete pad. If a 30,000-gallon tank is desired but space is limited, the diameter of the tank can decrease while height increases, but this adds additional cost due to tank engineering specifications.
What type of roof do I need?
Standing Seam Metal, Corrugated Metal, Asphalt / Bitumen / Composition Shingle, Concrete or Clay Tile, Solar Panels, Slate tile, painted tile. Materials to avoid for potable rainwater use: Cedar Shake, Copper, Lead, Biocides (check to see if levels are low enough not to cause harm to plants and other vegetation) When in doubt, collect a water sample and send it to a lab to know what chemicals (if any) are present in your water. The National Sanitation Foundation (NSF) provides a list of approved roof coatings.
What type of maintenance is required?
Our systems when fitted with appropriate gutter covers and our automatic first-flush device incur very low maintenance. Maintenance is usually 2-3 times a year. This includes changing filters every couple of months and changing an ultraviolet light annually.
Are there tax breaks or incentives?
Central Texas offers rainwater harvesting rebates that vary by city, county, and utility.
Texas also exempts all rainwater collection equipment from state sales tax.
Rebates typically range from $0.25–$1.00 per gallon and may be capped by system cost or location.
