Media-Based Stormwater Filter Systems
  The Flexibility of Media-Based Stormwater Filter Systems
Media-based stormwater filtration systems are much more flexible in their design than their rigid, precast concrete structure would suggest. A brief look inside that durable housing identifies several design options these systems offer to further reinforce their flexibility. 
Just as each site differs in the way stormwater filtration practices are designed and deployed, state and local jurisdictions enforce a variety of regulations for pollutant removal. To address this, media filtration systems can be customized using various filter media to target site-specific pollutants.
