3: Rainwater Irrigation
Consider water conservation the next time you think about watering your lawn. You don't have to stop watering completely, but what if you could use rainwater instead?
The best way to water your lawn is to sit under your covered porch having a glass of wine during a rainstorm. Since that doesn't happen as frequently as lawns typically need, we often resort to man-made irrigation.
But watering lawns has an adverse affect on our environment. According to NASA, lawns account for more irrigation than any single crop in the United States. Lawns cover an estimated three times as much land as corn. Watering all that grass puts a strain on water supplies, not to mention a disruption in the Earth's water and carbon cycles. But rainwater can offset your irrigation problems.
You can harvest rainwater and store it in drums for future use. It's actually quite simple. All you need to do is catch it as it flows out of your gutter downspouts. You can buy elaborate systems or make your own rainwater collection system using food-grade plastic barrels. To water a lawn, you'll need an electric pump to create enough water pressure to power an irrigation system. For optimum results, you can even elevate your rain barrels and let gravity increase the water pressure.
