Rainwater collected from the roofs of your house or sheds provides high quality water that can be a valuable source of drinking water. The volume harvestable is dependent upon your roof catchment area, but can be quite substantial over the course of a year. This article will help you to know how much rainwater you can capture on your property. Before you can estimate how much rain you can potentially harvest month-to-month or in a year, you need to know how much rain could fall from the sky.
To work out the surface area, simply multiply the length in metres by width for square or rectangular roofs. The resulting figure represents the surface area of your roof in square metres. To calculate how much rainwater can be harvested, multiply your rainfall mm by your roof surface area m 2 being used to catch rainwater. One great feature is that the fittings are integral to the tank, so there is no risk of leaking at these vulnerable locations.
Also, fiberglass tanks can be painted with latex house paint to either camouflage or celebrate their appearance. When placing your tank in position, remember that water weighs over eight pounds per gallon. A 10, gallon tank weighs over 40 tons, so it needs to be placed on a smooth, level, stable foundation. Pump: There are many options available, from an economical pump that is great for do-it-yourselfers to a more powerful unit that has an increased flow rate.
Filtration and Sanitation: The filtration and sanitization system consists of three components: a five micron sediment filter, a three micron activated carbon filter, followed by an ultraviolet light sanitizer that can handle a flow up to 12 gallons per minute. Proper maintenance is critical. To schedule tours for groups or individuals please contact The Luling Foundation office at or at lulingfoundation sbcglobal.
