STORMFILTER DESIGN NOTES
STORMFILTER TREATMENT CAPACITY IS A FUNCTION OF THE CARTRIDGE SELECTION AND THE NUMBER OF CARTRIDGES. THE STANDARD VAULT
STYLE IS SHOWN WITH THE MAXIMUM NUMBER OF CARTRIDGES (11), VAULT STYLE OPTIONS INCLUDE, OUTLET BAY (11), FULL HEIGHT BAFFLE WALL
(12). STORMFILTER 6X12 PEAK HYDRAULIC CAPACITY IS 1.6 CFS. IF THE SITE CONDITIONS EXCEED 1.6 CFS AN UPSTREAM BYPASS STRUCTURE IS
REQUIRED.
