About Treatment Trains
Traditional stormwater criteria require both improving the quality and managing the quantity of runoff. A best practice is to incorporate pretreatment, detention and treatment into an integrated system. Many areas may require only some of these processes, while some areas may require all of them.
HDS — Swirl concentration and screening devices are effective at removing trash, debris and solids from runoff, even at high flows. CONTECH HDS systems include CDS®, Vortechs® and VortSentry® HS.
Detention — Store and discharge stormwater over time when runoff inflow exceeds the allowable discharge rate. Underground systems maximize property usage. CONTECH offers a full line of Corrugated Metal Pipe (CMP), Concrete and Plastic solutions.
Filtration — Scalable cartridge-based system removes the most challenging pollutants from runoff - including fine solids, heavy metals and total nutrients. CONTECH filtration systems include the Stormwater Management StormFilter® and MFS® system.

Pretreatment, Detention and Filtration
- Pretreatment with a CDS system to reduce mainenance
- Use CMP detention to slow rate of runoff to match predevelopment flow rates
- Provide detention upstream of filtration to reduce flow rates
- Extend maintenance intervals by removing sediment before filtration
- Remove fine pollutants including heavy metals and nutrients with the Stormwater Management StormFilter
