Hollow Floating Ball Covers for Wastewater Applications. Waterfowl fatalities and process fouling in municipal and industrial ponds can be prevented by covering ponds with a Floating Ball Cover system. Floating Ball Covers cover system is a proven and effective wildlife deterrent recognized by organizations such as the “US Fish and Wildlife Service”. The floating ball covers the entire surface of the water, making the pond unattractive to the birds. Other wildlife such as deer do not attempt to walk onto the cover, as the individual balls do not support the animal’s weight.
