Aqua-Swirl® | Stormwater Treatment System

Aqua-Swirl® Stormwater Treatment System is a custom engineered, post-construction flow-through water quality device designed to remove coarse sediment, debris and free floating oil by utilizing hydrodynamic separation technology. Aqua-Swirl® technology is a modular high flow rate treatment system that has no moving parts and operates under gravity flow conditions within a single swirl chamber. 

Aqua-Swirl® systems are available in various models based on stormwater performance requirements:
​All Aqua-Swirl® models are manufactured from lightweight high performance construction materials depending on project-specific location and needs.
The small footprint design combined with these lightweight and durable materials, eliminates the need for heavy lifting equipment during installation. 
​
Fabrication facilities are strategically located in the United States and England to better serve our customers by providing cost-effective and timely logistical solutions.

​Each unit includes lifting supports and stub-outs for the inlet and outlet piping to allow for quick and simple connection to the conveyance storm pipe. Traffic rated manhole frame & cover.

​Inspection and maintenance activities are easily performed from the surface without the need for confined space entry or special equipment. A vacuum truck is typically used to clean the swirl chamber.
