or inside the tank, where turbulence should be kept at a minimum to avoid stirring up the water. “Those are the things that we provide as a basic kit which would allow a contractor to install the tank for the irrigation requirements,” he said. The rain water can be filtered and diverted to the tank in a couple of different ways. All the downspouts could be routed to a single filter that is buried but accessible just below the surface of the ground or an individual filtering unit could be attached to each downspout The system could be scalable to the residential site. The company’s largest tank is 1700 gallons. Tanks could be coupled together to obtain the total volume of storage desired and to accommodate the size of the roof and how much rainfall is expected. The system’s use is not limited to the drought-ridden, heavily populated south. Even for areas of the north, such as in the Great Lakes region, the cisterns could be used to reduce stormwater impact on combined sewer systems and the effects of runoff as well as reduce homeowner’s water bills by using the rain water. The depth of bury for such tanks would depend on the depth of the frost line. “It can be implemented anywhere. There’s no reason it shouldn’t be,” Brown said. There’s also the potential for in-home, gray water applications. “The rain water doesn’t require that much treatment at all, just basic filtration, to make it suitable for any nonpotable requirements, whether it’s irrigation or toilet flushing, even car washing,” he said. “There is no need to be using potable water that is chlorinated and fluoridated to wash your car when the water that comes off the roof of your house is more than acceptable.” right out of the box, but rather address what we see as the immediate need and requirement,” Brown said, which is to provide people with an alternate supply of water. Built for corrosive wastewater containment, the Roth Global tanks are made of high-molecular weight, highdensity polyethylene, are durable, impervious to corrosion and flexible. As a vessel, they are more than acceptable for rainwater or potable water usage, Brown said. In the future, there may be potentials for other water-recycling applications. The tanks are manufactured for the onsite, wastewater-treatment industry, which has seen significant improvements in processes that have resulted in effluent that is highly clarified and is of high enough quality to be used for subsurface, drip-irrigation systems. It would be another way to lessen the demand on the potable water service to the home.
