There are many advantages. The greatest advantage is aesthetics. Drip irrigation systems are installed just below grade so there is no mound in the yard detracting from the view. Another advantage is the flexibility. Often you can avoid cutting down that favorite tree that you've grown to admire. It's also a great way to irrigate your lawn by recycling the water you've already used for other purposes.The disadvantage is the relatively short amount of time they have been in use. They contain many moving parts and its difficult to predict how expensive they will become to maintain as they age.
