 Rainwater Harvesting System
How does the RainKeeper system work?
Rainwater can be collected from roof downspouts, catch basins or other sources of runoff and used for many different applications. There are four main components associated with the RainKeeper rainwater harvesting system - collection/filtration, storage, Re-Use, and overflow. Collection systems vary depending on the site but are usually roof downspouts. Filtration can be achieved through downspout filters or in-line filters buried in the ground. Storage is typically in drinking water-rated poly tanks provided by Roth, but can be in concrete tanks, rubber bladders or other storage mechanisms. Re-Use discharge occurs through a floating intake and pump system that resides inside the tank, and a controller that is mounted outside the tank. An overflow to daylight needs to be provided in the event the tank is full when a precipitation event occurs.
What can the water be used for?
Applications include sprinkler systems, garden hoses, toilet flushing*, window washing, water features, irrigation systems, secondary fire suppression, car washing, or any other use for non-potable purposes. Controllers are available to mix well water or other water sources into the storage tank to assure adequate flow during periods of low precipitation.
*check codes before using water inside a dwelling or building
How much water can I collect? 1" of rainfall = 623 gallons for a 1000 sq. ft. roof. New England averages 44" of precipitation per year which yields 27,412 gallons of possible storage per year from 1,000 sq. ft. of roof area.
How much water do I need to collect and store?
The end use should determine the amount of water that should be collected and stored. Heavy applications such as sprinkler systems which operate daily will need to have large storage volumes to assure adequate supply, while light uses such as occasional hand watering from a spray nozzle will need less water storage. Typical tank sizes readily available range from 300-1,500 gallons, with interconnected tanks easily achievable for larger storage volumes. Contact us to help calculate the needs for your project.
What are the benefits of the RainKeeper rainwater harvesting system?
Capturing rainwater for re-use provides for reduced water bills, eliminates concerns over watering bans, is easy to connect and is virtually maintenance-free. This product provides for considerable environmental benefits which help improve the ecology for all of us.
How do I purchase and install a Rainkeeper rainwater harvesting system?
Local contractors such as landscapers, excavation contractors, and plumbers are the best source for purchasing and installing a complete system for a project. Technical support is provided to the site contractor if he or she has not installed a RainKeeper system previously. Systems are available for pick-up or delivery to the job site.
