Proprietary Stormwater Devices

General

Many companies offer devices or practices to treat stormwater runoff. These devices and practices use different mechanisms to remove pollutants from stormwater and therefore have differing levels of efficiency in meeting stormwater standards.

Advantages

  • Take up little space on site
  • Usually out of sight
  • May remove target contaminants for site
  • Option for site retrofits and redevelopment

Disadvantages

  • May not be cost effective
  • Increased frequency of maintenance

Companies have the option to have their devices and practices reviewed to see if any stormwater requirements may be met by using their product. As of June 11, 2018 the following products (with accompanying design methodologies) have been reviewed and approved:
