Rain water goes through a natural distillation process, called evaporation. When water turns into vapour it leaves all the chemicals and pollutants behind, this makes the water relatively pure and soft which is a great option for watering your plants. By capturing rain water to be used in your reticulation system you can reduce your bills and provide a healthier option for your garden and plants. A plant will thrive and on the collected water. When an area experiences drought, the rain water that has been captured may make all the difference in the survival of your plants and lawn. By installing a rain barrel you are reducing your impact on the environment and saving money.
