Product Information

The AquaShield™ stormwater filtration systems have been praised by local regulators, engineers, and contractors for their simple design and ease of installation. As the systems are fabricated from HDPE, contractors prefer the quick and simple installation of our structures, which saves them money. The AquaShield™ line of patented water treatment products provide many levels of treatment.

AquaShield Filtration System

AquaShield™ offers three essential alternatives for treating stormwater and industrial runoff: the Aqua-Swirl™ hydrodynamic separator, the Aqua-Filter™ stormwater filtration system, and the Aqua-Guardian™ catch basin insert. Other derivatives of these core products have been adapted for customers needing further enhanced water treatment. Our products distinguish themselves from other systems with their high performance and lightweight construction material, providing unmatched flexibility and adaptation to site-specific conditions. Each product arrives at the project job site completely assembled and ready for installation.


As stormwater enters the Aqua-Swirl™ by means of its tangential inlet pipe and flows across a radial baffle, a swirling (or vortex) pattern is produced within the chamber that enhances removal efficiency of pollutants. A combination of hydrodynamic and gravitational drag will force the floatable contaminants to migrate to the center where velocities are lowest and allows dynamic settling of solids at the bottom of the chamber.


The Aqua-Filter™ Stormwater Filtration System operates without any moving parts or valves, which simplifies the "treatment train" process. Its small footprint and modular design utilizes effective swirl technology of the Aqua-Swirl™ as pretreatment in conjunction with a filtration chamber to refine or polish the stormwater over a bed of media removing fine sediment, nutrients, petroleum hydrocarbons and heavy metals prior to discharge into sensitive receiving waters.


Surface stormwater flows into the Aqua-Guardian™ and accumulates in the sediment chamber to begin the treatment process of capturing pollutants. As the storm continues, water flows through a locking filter screen standpipe that disperses over filter media where fine sediment, petroleum hydrocarbons, nutrients and heavy metals are removed before exiting the catch basin insert through a perforated base plate.
