The use of rain water for irrigation is not only helping you to save money, but is also a healthier way of watering your plants. Like this, you will be filtering out deposits like calcium and lime, and chemicals like chlorine from your plants, lawn and underground water.
Designing a rain water system is simple and you can do it on your own in a day. First, you have to check what happens around your garden area during rainfall and which are the areas where the water may be wasted. Don’t forget about the water that falls on your home: you can collect the water from the downspouts. Calculate how much water you can harvest and how much water your garden usually needs. On the Internet you can easily find out the indices for your state’s average rainfall in any given month. By knowing the dimensions of the areas where you can collect water from, you’ll be able to calculate the amount of water you can harvest. Like this, you can predict how many rain barrels you’ll need to store the water. To choose a site for your rain barrel, find the downspout that is closest to the plants with the heaviest watering needs to absorb any overflow from the barrel.
A rain barrel is a device designed to catch runoff from your roof or other surfaces that don't absorb rain water naturally. A covered water barrel is recommended to help prevent insects and to keep the water clean. As far as styles go, you'll be able to find rain barrels in many different shapes and sizes. To distribute the water through a hose to the garden you can elevate the rain barrel or use a hose with a valve.
Once you built the rain barrel, you have to take care of it. Always keep it covered and, if the winter is very cold in your area, you might want to disconnect it during these periods to prevent repeated freezing that could cause cracks. Cover the downspout and drainage spots with netting or wire mesh to prevent mosquitoes and debris from getting in your water. Also, clean your roof and gutters at least once a year to minimize debris.
An alternative to the rain barrel is to create channels alongside your plants to direct the rain to them or to create a berm around your garden to keep the water in the area.
