Golf Courses: Irrigation and Sprinkler Heads. All biofouling organisms grow naturally in lakes, rivers, ponds, and channels carrying reclaimed water. They usually enter irrigation system as a microscopic life stage, passing easily through most filters. Without treatment they can spread through out the irrigation system. If necessary, they can go dormant for months in order to survive unfavorable conditions.Usually the first indication of biofouling at a golf course is in the debris screens of sprinkler heads. Fragments of material accumulate there after breaking off from larger mases growing inside the pipelines. Clogged sprinkler heads can be a major maintenance issue. Many of the newer models seem especially susceptible.he specific treatment prescribed by Bryo Technologies varies according to the fouling species, water chemistry, soil type, and other factors. What never changes is our absolute commitment to a healthy turf and balanced soil ecology.
