Now let's talk about how the roof and gutters connect to the water storage tank. First you need a component to screen out any organic matter. This helps to wash the roof by trapping the debris so that it will not enter the tank. Getting the rainwater moved from structure to storage is done with 4-inch plastic pipe and fittings. Connections can be made directly to tanks set next to or within a roof area. To have a tank set away from your house, a piping system must be constructed and the storage set up downhill from your roof. One 4-inch pipeline should be fitted for each 1500 square feet of roof surface. Storage tanks are made of a variety of materials. The choices include wood, fiberglass, polyethylene and steel. They can all be used for drinking as well as other purposes. The stored rain is in turn pulled out by an electric pump and supplied to points of use or to a pressure tank. A pressure pump and tank combo are required to push the rainwater evenly through the supply line. Rainwater ends up in a perfectly drinkable state with the use of in-line sediment and carbon filters and an electronic purifier to remove bacteria. |
