Upstream Treatment Configurations

Low Impact Design (LID) design involves managing runoff close to the source using small, decentralized system. The following suite of StormFilter configurations are easily incorporated on sites where LID site design is recommended. These low-cost, lowdrop, point-of-entry systems also work well when you have a compact drainage area.

CatchBasin

• Provides a low cost, low drop, point-of-entry configuration
• Treats sheet flow from small sites
• Uses drop from the inlet grate to the conveyance pipe to drive the passive filtration cartridges

Curb Inlet

• Provides a low drop, point-of-entry configuration
• Accommodates curb inlet openings from 3 to 10 feet long
• Uses drop from the curb inlet to the conveyance pipe to drive the passive filtration cartridges

Linear Grate StormFilter / Linear StormFilter

• Can be designed to meet volume based sizing requirements
• Can be installed in place of and similar to a typical catch basin
• No confined space entry required for maintenance
• Accommodates up to 29 StormFilter cartridges

Downstream Treatment Configurations

Conventional stormwater treatment involves collecting, conveying and treating stormwater runoff with an end of pipe treatment system before discharging off-site. StormFilter configurations suitable for these applications are listed below and can be engineered to treat a wide range of flows.

Vault / Manhole

• Treats small to medium sized sites
• Simple installation - arrives on-site fully assembled

CON/SPAN / High Flow

• Treats flows from large sites
• Consists of large, precast components designed for
  easy assembly on-site
• Several configurations available, including: CON/SPAN,
  Panel Vault, Box Culvert, or Cast-In-Place
• Download CON/SPAN StormFilter Installation Guide

Volume

• Meets volume-based stormwater treatment regulations
• Captures and treats specific water quality volume (WQv)
• Provides treatment and control the discharge rate
• Can be designed to capture all, or a portion, of the WQv

Peak Diversion StormFilter

• Provides off-line bypass and treatment in one structure
• Eliminates material and installation cost of additional structures to bypass peak flows
• Reduces the overall footprint of the treatment system, avoiding utility and right-of-way conflicts
• Internal weir allows high peak flows with low hydraulic head losses
• Accommodates large inlet and outlet pipes (up to 36”) for high flow applications
