If you live in an arid place, such as the Southwest, rainfall is limited and evaporation rates are rapid. Rather than use your precious drinking water to irrigate your garden, harvesting rainwater is an effective way to meet the moisture needs of your trees and garden. Rainwater collection also reduces the strain on public resources and provides you with a free way to keep water for your property. When harvesting water you must have a way to capture, divert and store rainwater for later use. Does this Spark an idea?
Instructions
1. Locate a place on your property that will provide run-off for rainwater such as a roof or raised solid surface. When it rains, look for a place where a good amount of water runs off your roof.
2. Dig a base a few inches deep where you want to put the barrel. Place a layer of cinder blocks in the hole to make it level for the barrel. Place the barrel on top of the blocks.
3. Measure and cut a hole in the top of barrel so the water can get inside. The size of the hole will depend on the size of your delivery system. Install a leaf catch at the top of the barrel to prevent dead leaves from collecting inside.
4. Create a way to divert the water from the roof into the barrel. Attach a downspout to your gutter and direct it into the opening at the top of the barrel. Cut the downspout with a hacksaw so it rests just above the barrel's inlet. An alternative option is setting up a rain chain which will usher water from your roof or raised surface into the barrel.
5. Drill a hole at the top of the barrel to accommodate an overflow pipe with a diameter of at least 2 inches. Thread the pipe directly into the barrel. Place Teflon tape and silicon caulking around the threads to secure it. Point pipe so the water overflows away from the house.
6. Install a spigot in your barrel. Drill a 15/16" hole for a 3/4" hose spigot a few inches from the base of the barrel. Thread the spigot into the hole. Secure with washers on both sides and a nut inside. Place Teflon tape and silicon caulking around the threads to secure it.
7. Connect a soaker hose to the spigot and lead it out to your garden. Turn on the valve whenever you want to water your garden. The force of gravity will take the water out to your plants. Alternatively, you can use the spigot to fill a watering can and deliver water that way.
