We get 1000 mm of rain a year. Do we really need a sprinkler system?

If it rained at your house every three days – the same exact amount each time – you probably wouldn’t need a sprinkler system. But nature doesn’t work that way, and the only way to ensure healthy, lush growth is to make certain your lawn and plants receive a regularly timed, evenly measured amount of water. In the dry season, when there is little or no rain, your yard can suffer damge after just a few days without water.
