The Aqua-Swirl® has been designed and fabricated as a lightweight unit eliminating the need for heavy lifting equipment during installation. This combined with the inclusion of stub-outs, lifting eyes and no on-site assembly facilitates easy installation.

Fabrication facilities are strategically located in the United States, Canada and England better serve our customers by providing cost-effective and timely logistical solutions.

Independent laboratory and field-testing programs verify that the Aqua-Swirl® models achieve up to 80% TSS removal.

Since the system utilizes a single chamber, inspection and maintenance activities are simplified without the need for confined space entry or the use of special equipment. A vacuum truck is typically used to clean the chamber.

Easy and open access to the chamber bottom, from the surface, serves to facilitate inspections and maintenance while reducing long term operational labor and equipment costs.

The Aqua-Swirl® stormwater treatment system can be designed to fit a variety of configurations, including both offline and inline. Furthermore, the optimized footprint to treatment flow rate reduces the required excavation size.

Inlet and outlet stubs can also be angled to fit most applications. While the invert of the connections are at the same elevation, meaning the unit can easily be connected to the existing stormwater conveyance system.

Independent laboratory and field testing programs confirm that the Aqua-Swirl® achieves over 85% sediment removal on a net annual basis. The 27 month field test further demonstrated its long-term functionality and retention of fine-grained clay loam textured sediment. Additional information can be provided for the NJCAT verified laboratory and field performance testing programs.

Compatible with LID Designs

Low Impact Development (LID) design practices can be enhanced or complemented by the Aqua-Swirl™. Pretreatment for rainwater harvesting systems that use underground or above ground structures can incorporate the Aqua-Swirl™ system. It can also be used as part of a treatment train using underground infiltration structures such as the StormTank™. The small footprint device is compatible with a variety of urban LID designs. Contact AquaShield™ to learn more about including the Aqua-Swirl™ in your innovative LID design.

LEED Credits

The Aqua-Swirl® can directly contribute to gaining one (1) LEED Credits for Sustainable Sites (SS) 6.2, Stormwater Design - Quality Control. This credit is considered to meet the SS 6.2 criteria of having completed independent testing to demonstrate 80% TSS removal on a net annual basis. The Aqua-Swirl® can also help contribute to gaining several other credits within the USGCB LEED program.
