Injection System

We are running the injection system for the first time this evening.  We have to flush the untreated water in the irrigation pipes by running water on the fairways and tees.  We are running the system so we can water in a wetting agent with treated water later in the week.  The untreated water slows or inhibits water from moving through the green profiles.  Below is a link for further information on the injection system.
