who does it? do you have it stored in tanks, barrels, do you have a set up off your roof gutters? I think I need to do this. Free water. |

When we get a good storm out here, I crack open one of my 45g barrels and stab my homemade rainwater fillterer (cheesecloth over a large funnel) into the spout.....In two years, I've collected 19 barrels.....could probably catch more if I wasn't picky about filtering.....anyways, I usually use a full barrel in about 2 months filling up my 5g jobsite jug.... |

I plan to catch the run-off from an outbuilding for my garden. Collecting a few more materials right now but I will post pics of the process when I get started. I heard some areas have restictions on this however that means nothing to me. |

I see...any water falling from the sky is not yours,it has been legally allocated by the state.. What a bunch of BS. Nice set up in the pic on that link. |

Check at cola manufacturing plants. The only Coke distributor in the Carolinas is in Charlotte, and I have the contact's name and number. The closest other Coke mfg's is West Virginia and Atlanta. I havent checked other areas or other food producers. The barrels are $10 cost (at Coke in Charlotte NC). They are easily cleaned with a little bleach and a hose pipe. You can get them new on some sites online for about $100 plus shipping. I have a site showing how to allocate an overflow valve on one barrel to flow over into another. Simple setup really. You drill a 1-2"hole about 4-6" from the top on the side of two barrels. about 18" of 1-2" pvc pipe is used to pipe the overflow over into the second barrel. If you have a torrential downpour, you may be glad that you used 2" pipe so as to catch all the overflow. Also you can put a faucet spigot near the bottom of the barrels, raise the barrels up on blocks, and make it easier to put the water to use with a 5 gallon bucket or whatever you use to transport the water. I calculated that in my area, a 1000 sf roof in this rainfall zone could mean well over 10,000+ gallons per year. That is, catching every drop that comes off the roof, of course. I'd have to dig a 1000 gallon cistern to catch that much. FORMULA FOR CALCULATING RAINWATER CACHE SIZE: square footage of roof area X .6 = gallons per 1 inch of rain. gallons per 1 inch of rain X .average inches rain per month = amount available for collection Example Square footage of roof area (length x width) 1800 sq. ft 1800 x .6 = 1080 gallons Average inches rain per month in most of Florida is 3 inches - this does not include June, July, August and September which are about double that. 1080 gallons x 3 = 3240 gallons collected Let us assume 2 people live in this home. With each person using 69 gallons of water per day (this is average), that is 138 gallons per day or 966 gallons per week and 3864 gallons per month. Considering the frequency of rain, a 1000 gallon to 2000 gallon storage capacity would be a good fit for this home. |
