Table of approved technologies
The following table lists the devices that have received a designation through the TAPE process.
In addition to our certification, local jurisdiction approval is required (and not guaranteed) for installation of treatment technologies we have evaluated and given a use designation.
This table walks viewers through an excel spreadsheet of all the contact information for the approved stormwater technologies certified through the TAPE program.
