Irrigation Systems are sprinkler systems installed underground. A series of pipes and sprinkler heads that are arranged around a yard to help provide full and even water coverage. These systems are wonderful to use as long as you don't abuse the convenience. As mentioned in the "How often should I water my lawn?" article, you don't want to frequently water you lawn. With systems that can be set to a timer, there is a tendency to water too frequently or at inappropriate times because we set the timers and let it go. 

Managed responsibly, these systems are a great way to ensure your yard is properly watered.
