Depending on where you live, anywhere from 30 - 70% of residential water is used for outdoor use, such as lawn and landscape irrigation. This is the EM and I’m ES. According to the EPA, some experts estimate that more than 50 percent of commercial and residential irrigation water use goes to waste due to evaporation, wind, improper system design, or overwatering.
One way you can prevent that is by changing from lawn sprinklers to a drip irrigation system – which allows the controlled application of water at a very low flow over a prolonged period. It differs from conventional watering systems in that the water just goes where it is needed and the soil does not get supersaturated. When the rate of drip irrigation is adjusted correctly, there are no puddles of water and no runoff. Other ways to save water are to use a timer and rain sensor.
