Hollow Plastic Ball Covers for Reservoirs & Water Storage
The challenge
- Evaporative water loss in a multi-acre open reservoir
- Algae and cyanobacteria affecting water quality
- Sunlight-driven formation of disinfection byproducts
- Need for potable-water-appropriate materials
How Armor Ball® helps
Floated across a reservoir, Armor Ball® cuts the open surface area that drives evaporation, conserving up to 90% of evaporative loss while shading the water to limit algae and UV-driven reactions. The balls are molded from UV-stabilized HDPE specified for potable-water/food-contact use when required, with NSF/ANSI 61 documentation where applicable available on request.

FAQ
Reservoirs & Water Storage — questions answered
How much water can a ball cover save on a reservoir?
By covering 91% of the surface, Armor Ball® reduces evaporative water loss up to 90% per AWTT published data; actual savings depend on local climate, wind, and the reservoir's surface area.
Is the material safe for potable-water reservoirs?
Armor Ball® is molded from UV-stabilized HDPE specified for potable-water/food-contact use when required. Material certifications, SDS, and NSF/ANSI 61 documentation where applicable are available on request.
