• The average 25x40ft roof sheds about 600 gallons of water in 1 hour of moderate rainfall! That's enough to fill over 15 bathtubs!
(Use our Rain Harvest Calculator to estimate your potential harvest!)


• The average family uses around 350 gallons of water per day.


• Less than 5% of water is used for things like drinking and cooking. Once filtered correctly, rainwater is considered potable, or safe for consumption.


• Non-potable rainwater still needs to be filtered, but can be used for washing machines, flushing toilets, washing cars and watering gardens. Since these applications account for the majority of residential usage, even non-potable systems can make a drastic difference in the home's water bill, environmental impact and efficiency.





• Plants love rainwater! It's preferred over municipal water for it's close to neutral PH level, high nitrogen content and lack of added chemicals.


• During the summer months, gardens and landscaping can account for 50-70% of the home's water usage!


• Just by using a simple Rain Barrel system, homeowners can collect enough free, safe water for their lawns and gardens! Rain barrels require very little plumbing and are easy to install.






• Harvesting systems can be connected directly to a building's plumbing!


• Rainwater has no hardness, which prevents build up in pipes and appliances.


• Many people harvest rainwater as an important step toward a sustainable home or business, but did you know it saves money?


• Once a system is installed, it not only ensures a safe, dependable water source in case of emergency, but the water collected is FREE! Most systems will pay for themselves by reducing or eliminating the water bill.






• Rainwater contains no chlorination or fluoride and is healthier than chemically-treated tap water.


• Even most bottled water has a small about of fluoride and the plastic bottles contribute to our carbon footprint, polution and litter. Plastic bottles also contain Phthalate that can leech into the water inside.


• The average consumer pays around $500 per year for bottled water.








• When chemically-treated tap water is used outdoors, it is introduced directly into the environment and can contaminate natual water sources.


• Harvesting rainwater reduces erosion and flooding around downspouts and also helps to control storm water runoff. Durring heavy rains, municipal storm water infrastructure can be overwhelmed, which can cause contaminated water and sewage to overflow into ground water.


• When rainwater falls onto impervious surfaces, such as concrete and asphalt, it doesn't soak into the ground, which prevents it from replenishing ground water. As it flows across parking lots and other man made structures, it picks up harmful pollutants which are then introduced to the water supply. By collecting rainwater, we are reducing the amount of water that would add to this run off pollution.
