I have been mowing lawns now for 9 years and have been thinking about starting to offer irrigation services to customers. I don't have very much experience with irrigation systems so I will take some coarses. My first question is would local community colleges have irrigation type classes? And what certification would I need to have to do the maintenance? I figure that I can take these classes right after I graduate high school or just before. So any suggestions on what coarses/classes to take, where to take them, and what certification I need to maintain irrigation systems would be great. Thanks for your help.
