Custom & Retrofit Applications
The Aqua-Swirl® Stormwater Treatment System can be custom designed to fit a variety of field applications to include both offline and inline configurations. Retrofit applications are often suitable for Aqua-Swirl™ BYP (inline) systems when local guidelines allow its use. The angles for inlet and outlet lines can also be modified to fit most applications. With the invert of the inlet and outlet pipe at the same elevation, the Aqua-Swirl® can easily be connected directly to the existing stormwater conveyance system. Furthermore, given the modular small footprint design of the Aqua-Swirl®, the potential to disturb existing infrastructure utilities or surface features is minimized.
Easy Installation, Inspection & Maintenance
The Aqua-Swirl® has been designed and fabricated as a lightweight, durable and modular unit with no moving parts or on-site assembly requirements. The inclusion of stub-outs and lifting supports also facilitate easy installation. Since the system utilizes a single swirl chamber, inspection and maintenance activities are simplified without the need for confined space entry or the use of special equipment. Easy and open access to the swirl chamber from the surface serves to facilitate inspections and maintenance while reducing long term operational labor and equipment costs.
Proven Performance and Functionality
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.
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.
