For 500 square feet of landscaping, this conversion saves at least 15 gallons every time you irrigate. If you irrigate twice a week, that adds up to potentially 1,560 gallons a year.
Drip systems put water where plants need it most –at the roots. But remember: Drip systems emit water much more slowly than sprinklers. A typical pop-up sprinkler head sprays 2 gallons per minute; drip systems emit 1 to 2 gallons PER HOUR. Most shrubs and perennials need at least 1 gallon a week. So set your irrigation timer accordingly.
