With a garden pump, or irrigation pump, you can water your garden sustainably. This pump draws water from a storage area. For example, a rain barrel where you store water from a rainstorm or a ditch. Connect the garden pump to a garden hose and sprinkler and automatically water the plants and your lawn. The higher the flow capacity of the garden pump, the more water it moves at once. You can control some irrigation pumps with an app, which makes it easy to turn it on and off.
