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.

Outcomes

Up to 90% less evaporative water loss
Reduced algae and UV-driven water-quality issues
Potable-appropriate materials when required
25+ year design life, 10-year warranty

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.
