Texas Rainwater Harvesting - Rainwater Collection Tanks and Applications

Rainwater Harvesting Applications and Tanks



Simple application:
Rainwater is fed directly into a polyethylene tank via gravity (dry system). The stored rainwater is used to water plants nearby. The water pressure for the end use is supplied solely from gravity; no pump is used.

galvanized rainwater harvesting tank Wet system consisting of a small galvanized tank with first flush filtration at the downspouts. In a wet system, rainwater collected from the roof goes into an air-tight PVC pipe connected to underground pipes and is channeled back up to the top of the tank via a riser pipe located near the tank. There must be enough of a drop from the downspout to the top of the tank to allow gravity (through water pressure) to fill the tank. rainwater filtration first flush



supplemental water, make-up water Galvanized tank connected to an irrigation system. The system has a roof washer to filter the rainwater before it enters the tank. The rainwater system is integrated with the irrigation system. It has make-up water capability, conforming to TCEQ cross connection rules, which automatically adds municipal water to the tank when water in the tank falls below a specified level. When the irrigation controller's timer calls for irrigation, a relay starts power to the pump, and floats inside the tank check to see if municipal water needs to be added to the tank.

rainwater purification - UV light disenfection Potable rainwater harvesting systems use UV light to sterilize the water. A pump pressurizes the water for use inside the house or for non-potable landscape use. Filters remove sediment from the rainwater before it enters the pump. Check valves and pressure gauges protect the pump. rainwater pump
