Hydrodynamic 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 storm water manufactured treatment device (MTD) based on recent laboratory test results.

DVS performance has been verified by the New Jersey Corp. for Advanced Technology (NJCAT), a comprehensive, rigorous, and recognized verification program.

“This is just a re-certification of the Dual Vortex Separator under the new NJDEP test protocol," said Jay Holtz, director of engineering for Oldcastle Stormwater Solutions. "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 storm water 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 alternative for best management practice (BMP) implementation in new and retrofit applications where space is limited and effective storm water treatment is required. The unit can be used to help meet total maximum daily load requirements for removal of solids, trash, debris and petroleum hydrocarbons. The unit can also be a critical component of a comprehensive low impact development strategy to help increase the service life of infiltration, detention and retention systems as well as other storm water 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.
