Rainwater Harvesting Systems 

Through our own experiences with rainwater harvesting systems, TXRWS has developed a technology that makes it easier to collect cleaner water. Unlike traditional rainwater harvesting systems, our technology is low maintenance and yields higher water quality. Whether you're needing clean water for your home, irrigation, help managing stormwater run-off, TCEQ batch detention design, or fire protection water tanks, TXRWS, the rainwater harvesting company you can rely on is here to help you achieve your conservation goals. If you’re interested in rainwater harvesting in Austin or the surrounding areas, the team at TXRWS is here to help. We’re a water storage tank supplier that will make collecting and using water easy.

COLLECTION SHOULD BE EASY

TXRWS
Auto-Flush

Controller

Our solution to a better, smarter, easier rain collection system is our TXRWS Auto-Flush Controller. This system controller determines how much water will be flushed and the length of time to wait after a rain event before flushing your system of standing water. It converts a traditional wet system to a dry system automatically. This controller can make using the water you’ve collected simpler and more efficient, so if that sounds like the right technology for you, don’t hesitate to contact us at TXRWS. 

Enclosed in a NEMA 4x / IP66 rated box, the controller operates on low voltage power and which can also be supported with a small solar power array for remote installations. 

Programmable features that allow for easy operation

  • How much does it cost?
    A typical above-ground 30,000 gallon system for potable use costs between $0.95 - $1.40 a gallon. Smaller systems can sometimes cost between $2 to $3 a gallon. Factors that affect price are type of soil for excavation/trenching, collection area square footage, distance between tank and house, tank pad topography and type of pad for tank.
  • How big are the tanks?
    We install tanks a small as 10,000 gallons and as large as 300,000 gallons. We can install tanks above and below ground as well as inside the concrete foundation of a house/structure.
  • 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?
    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.
  • Any tax breaks?
    Different counties and cities in central Texas have different tax breaks and or rebate programs. Click on a locality for more information.

  • What makes your technology different?
    Our technology uses a low voltage controller than can manage different parts of a rainwater collection system without any human intervention. The controller has features that include the following: Automatic first flush – A rain sensor communicates with an automatic valve to automatically flush the dirty water that initially is washed off a roof. Configurable setting from small to large flush amount improves water quality. Simple design eliminates maintenance and the need for extra equipment. Other systems have first-flush tanks that have to be maintained frequently in order for them to work properly. First flush tanks have their drawbacks during hard rain events. Automatic draining - Automatic valve automatically dries out system after the rain event. No and smelly standing water in pipes Water Protection - Automatic shutoff feature that prevents draining an entire tank accidently, Controller can learn water usage behaviors and adapts to site usage patterns Staging – controller can manage transfer pump if main rainwater tanks are higher than structure, can accommodate single pump system or duplex pumping system, simplifies collection from multiple/complex roof surfaces, Main tank(s) can be hidden, placed remotely, or even at different elevations Remote - Controller can be powered by small solar power array for “off-grid” systems Recapture – controller can recapture all of the remaining water in downspouts rather than just draining this water at the end of a rain event. This water at the end of a rain event is the cleanest water to collect. Automatic backup valve – controller can manage an automatic valve to switch over to a 2ndary water source when the water in the rainwater tank is almost empty.
  • What size tank do I need?
    We generally recommend 7,500 gallons of storage per person to get through long dry periods in central Texas. A family of three would want to have around 22,000 gallons of storage for household use.
  • How much water can I collect?
    660 gallons can be collected for every 1,000 sq. ft of footprint of a structure. A one story 3,000 sq. ft. home can collect 1,980 gallons for every inch of rain where a two story 3,000 sq. ft home will only collect 990 gallons.

About the Owner

Scott Solkofske

Scott was first introduced to rainwater collection systems when his family moved out to the Texas Hill Country in 2007. The home they purchased had an old and antiquated system that was challenged by large heritage trees, extreme elevations, and pipes held together with duct tape and tinfoil! The family immediately noticed all of the benefits from using rainwater compared to well water or municipal water: soft skin and hair, cleaner laundry and appliances, happy plants, and a happy septic system.  However, the system required constant work and Scott kept telling himself “this system can be better.” Scott was dealing with several issues: clogged gutters and downspouts, smelly/dirty water, and overflow problems. He knew there had to be a way to collect more water, cleaner water, with less work. The tools and knowledge that he has gained from making improvements to his system over the years has helped him develop new technology that he uses on his current catchment designs and builds today.  His family used to laugh at him when he would run around in the rain trying to perfect his system to collect the most water possible. Fortunately these days are now over, and his systems are right as rain! 

With a strong background in healthcare and information technology, Scott saw a need for rainwater systems to collect only clean water yet keep maintenance at a minimum. He has developed new technology in the rainwater collection industry and offers features/options that improve water quality and minimize system maintenance. It’s these features that allow his clients to achieve their water conservation goals by collecting clean rainwater with ease. His turn-key systems deal with rainwater, irrigation, stormwater run-off, and fire protection water tanks. With a great eye for detail, Scott focuses on quality rather than quantity and believes in providing personalized customer service to each and every project.

In his downtime, Scott enjoys playing his saxophone around Austin, working on old cars, and spending time with his wife and their five dogs and dog cat.
