Guardian Environmental Products

Guardian Environmental Products, operating under the brand GuardWater, is a manufacturer of capital equipment for the water and wastewater industry headquartered in Charleston, West Virginia. Drawing on over 50 years of experience in chain and flight clarifier technology, the company has evolved alongside the industry's shift from cast iron systems to non-metallic and stainless steel configurations. Guardian's primary product is the TROLL Collector System, a proprietary rectangular clarifier mechanism available in both non-metallic and stainless steel materials. The company is one of the few manufacturers in its segment holding both NSF-61 and NSF-372 certifications for drinking water compliance. Beyond new equipment, Guardian provides retrofit parts and complete systems compatible with rectangular clarifiers from all major manufacturers, positioning itself as a comprehensive source for both new installations and rehabilitation projects. Their product range also includes control systems for clarifier drives, custom-engineered weirs, effluent troughs, and baffles for flow distribution optimization, dissolved air flotation (DAF) systems for wastewater and industrial applications, and scum collection pipes for surface material removal. Guardian works directly with end users and consulting engineers and is an active participant in WEFTEC and state industry trade shows across the United States.
