  • Why should I choose rainwater over tap water?
    Harvesting rainwater is the most effective way to ensure a reliable water supply for your home while contributing to water conservation in your community. You’ll no longer be affected by rising water costs or watering restrictions, and you’ll experience a sense of pride in owning and operating your own water system. Rainwater is naturally soft and doesn’t require processing through a water softener, meaning your water will no longer contain sodium or potassium chlorideboth of which are known to have adverse health effects. Use of naturally soft rainwater also results in longer-lasting and better-functioning home appliances. Dishwashers, for example, leave dishes much cleaner than with softened tap water. Additional benefits include better-tasting water, cleaner and softer clothes, less use of conditioner when showering, and reduced need for pool additives, since rainwater is nearly pH-neutral.


  • How much does a typical rainwater catchment system cost?
    A typical whole-house potable water system will vary in cost depending on the tank size, the distance of the tank from the home or catchment surface, the amount of grading involved in attaining a level tank site, and the size of the home. Typically, a 30,000-gallon system will cost approximately $1 per stored gallon of water, which equates to between $29,000 - $33,000. The smaller the tank, the higher the cost per stored gallon of water, so that a 20,000-gallon system will typically cost between $22,000 - $27,000. A larger 65,000-gallon system would cost between $53,000 - $58,000, making for a lower cost per stored gallon of water.


  • What is rainwater harvesting?
    Rainwater harvesting involves collecting natural rainwater for consumption and household use. In various forms, the technique has been practiced for millennia as a practical, safe and reliable solution to water acquisition. Traditionally used in areas of the world experiencing limited resource availability, rainwater harvesting is becoming increasingly common in developed nations where reliable access to clean water is becoming increasingly difficult (such as the situation in Texas brought about by prolonged drought).
  • How large are rainwater harvesting tanks?
    Harvesting tanks come in all shapes and sizes, ranging from 10 to 100,000 gallons. The most popular size for residential use is the 2,500 gallon tank. Tanks can be made according to custom specifications and can be constructed with plastic, metal, cement or fiberglass. There are even “bladder” containment systems that can be made to fit under crawl spaces, in between joists on a deck or floor, or in basements.
  • What is involved in maintaining a rainwater harvesting system?
    For the most part, rainwater harvesting systems depend on unobstructed and correctly functioning gutters and downspouts for effective water collection. We also recommend regular maintenance on system components, including tanks, pumps, valves and fixtures. Maintenance on systems designed for potable home use will vary depending on the filtration method used, but typically involves cleaning or replacing filters and UV light bulbs. We can take care of your maintenance needs, including any necessary repairs, whether we or someone else installed the rainwater catchment system. Call us or contact us via email to set up a maintenance schedule with us – we’ll be happy to serve you!


  • What can I use rainwater for?
    Rainwater can replace virtually every imaginable use case of tap water and offers a cleaner, more cost-effective and greener solution to water usage. A few of the many applications of harvested rainwater include use for drinking water (with a filtration and treatment system), landscape irrigation, allowing for watering during water restrictions, providing water for livestock, filling pools, foundation stabilization, washing vehicles (rainwater provides a spotless rinse) and even fire fighting via tanks outfitted with fire hose connectors.
  • Can I use rainwater for drinking and bathing?
    Yes, a potable (drinking) water system can be used for consumption, cooking, bathing and filling pools. These systems most commonly involve specialized filters and employ UV light treatment to eliminate any impurities in the water. There are a number of alternative treatment methods for potable water systems that our team is happy to discuss with you.
