Dual Vortex Separator Receives NJDEP Certification

Oldcastle Stormwater Solutions has received certification from the New Jersey Department of Environmental Protection (NJDEP) for its hydrodynamic separator, the Dual Vortex Separator (DVS), as an approved stormwater manufactured treatment device (MTD) based on recent laboratory test results.

DVS performance has been verified by the New Jersey Corporation for Advanced Technology (NJCAT), one of the most comprehensive, rigorous, and recognized verification programs in the United States, and is now certified by NJDEP.

Jay Holtz, Director of Engineering for Oldcastle Stormwater Solutions, stated “This is just a re-certification of the Dual Vortex Separator under the new NJDEP test protocol. But we made some incremental improvements to the unit to enhance performance and allow online application. The current NJDEP approval will give designers an effective tool to meet stormwater treatment requirements with full engineering design support and provide a cost-effective and easy to maintain option for contractors and owners. We’re excited to be able to offer such a comprehensive solution.”

The DVS offers an innovative and economic alternative for Best Management Practice (BMP) implementation in new and retrofit applications where space is limited and effective stormwater treatment is required. The DVS unit can be used to help meet Total Maximum Daily Load (TMDL) requirements for removal of solids, trash, debris, and petroleum hydrocarbons. The unit can also be a critical component of a comprehensive Low Impact Development (LID) strategy to help increase the service life of infiltration, detention, and retention systems as well as other stormwater treatment BMPs. The DVS is approved for online application by NJDEP. This can eliminate the need for a separate high flow bypass structure upstream of the unit thereby reducing project costs.
