Rainwater collection is much easier to do than I first thought. With only slight modifications to a gutter system on a home you can divert rain water in the gutter into large capacity containers that can store hundreds of gallons of non-potable water. Each time it rains the water used is replenished and freshened.
With little more than adjusting your gutter’s downspout to pour into a rain barrel you can start to capture rainwater. Adding screens or filters to the downspout and a lid to the barrel will help keep debris out of the barrel. There are more elaborate things you can buy to automate the procedure of rainwater capture that will help keep debris and creatures out of your supply.
The amount of water coming from your roof system far more than you may think. Whatever the layout or pitch of your roof that the square footage of your house will ascertain how much rainwater is diverted into your gutter system. The key will be the design of your gutter system. Without a good gutter system harvesting rainwater will be difficult.
Harvesting rainwater does not need to be expensive. Watch this video by southernprepper1 as he describes an inexpensive method of harvesting rainwater.
Rainwater Capture Systems Can Be Elaborate
There are several good videos available that teach rainwater collection. This link takes you to a series of videos which provide detailed directions how. Watching these videos will teach you how you can link multiple storage components together. You’ll also find out about overflow systems to maintain your barrels full.
As you saw in the video rainwater capture systems can store hundreds or thousands of gallons and be automatic. Rotating your water source by using it to water gardens can help keep the water clean. Using your rainwater regularly will also keep algae growth to a minimum.
Before beginning this project you want to appear at your local regulations. Local laws may limit capturing of rainwater.
I do plan on duplicating this setup at our dwelling. In our neighborhood I am not allowed to have rain barrels outside the house. I will set ours up in the garage and route our downspouts indoors to fill them. This will cost me more than an outside system but it will be well worth the effort and expense.
Regardless of what size of capture system you have you’re going to need to purify the rainwater before you drink it. Please pay close attention to this detail as rainwater does contain impurities that you do not want to drink.
