UHS Parking Garage: April 2011

The Problem:

Stormwater Quality has been an increasing concern for engineers and municipalities alike.  On this project, the engineer was faced with treating the drainage coming off a parking garage.  In itself, this generally is not an issue.  However, the engineer had to design around a very small area in which to add water quality measures.

The Solution:

A CDS 2015-4-C and CDS 3035-6-C Stormwater Quality Device were designed and installed.  Both of these units were designed to meet the current City of Knoville regulations.

The CDS system uses continuous deflective separation – a combination of swirl concentration and patented indirect screening – to provide you with a uniquely capable product. It effectively screens, separates and traps debris, sediment and oil from stormwater runoff.

With the CDS system you’ll get:

One-of-a-Kind Screening Technology:

  • Captures and retains 100% of floatables
  • Self-cleaning screen – only non-blocking screening technology available
  • Water velocities within the swirl chamber continually shear debris off the screen to keep it clean
  • Various screening apertures available

Proven Performance:

  • Performance verified by NJ CAT and WA DOE

Excellent Pollutant Retention:

  • Isolated Storage Sump eliminates washout potential
  • Oil Baffle improves hydrocarbon removal

Multiple Options to Meet Site-Specific Needs:

  • Inline, offline, grate inlet and drop inlet
  • Multiple pipe inlets – eliminate the need for junction manholes and offset pipe orientations
  • Internal and external bypass available
  • High treatment flow capacity – up to 300 cfs
