There are two main types of irrigation systems: drip systems and sprinkler systems. Drip systems apply water directly to the soil using drip tubes or emitters and are well-suited for garden beds and individual plants. Sprinkler systems apply water over head using spray or rotary heads and are used for irrigating turf grass areas. Both systems have advantages and disadvantages related to factors like installation, maintenance, water pressure requirements, and rate of water delivery. Properly planning and installing an irrigation system involves dividing the landscape into zones based on water needs and controlling each zone with a valve and irrigation controller.
