Rainwater collection from roof.

Around 600 gallons of rainwater can be harvested from about one inch of rain if it falls from a thousand square foot roof. Rainwater runoff from your roof contains a mix of materials deposited by pollution and animals as well as chemicals used in the manufacture of the shingles. Rainwater harvesting is collecting the run off from a structure or other impervious surface in order to store it for later use. Collecting rainwater is a technique that has been practiced for centuries as an environmentally friendly method to collect rain for distribution in gardens and across landscaping.

Adding chlorine or iodine to water does not protect against chemicals and some parasites are very chlorine tolerant. Rain barrels for example do not provide any type of disinfection or filtration. Fumes from industry and traffic. Well we thought so too.

Dirt and germs can be washed into collected rainwater from the roof especially when rain follows several days of dry weather 3 4 9. That is why my husband and i began harvesting our rainwater. Did you know the average roof collects 600 gallons 2 271 2 l of water for every inch of rainfall. The rain will collect in gutters that channel the water into downspouts and then into some sort of storage vessel.

Doesn t that sound like a lot of water that you could harvest and use for free.
