Today we are starting to blow out the irrigation systems on both golf courses. This is quite an undertaking because we have a very large irrigation system with over 3500 sprinkler heads that all need to have the water blown out of them. We first gravity drain the lines as much as we can. We then hook up 2 - 750 cfm air compressors to our system. We usually have 4 staff members per golf course turning on heads to get the water out. This is a 2 day process and we will be completed by tomorrow afternoon.
