Designed specifically for those projects where there just isn't enough room for a large underground vault, or access becomes a real issue, I.e. placement in parking lot areas isn't a option due to heavy vehicular traffic.

Narrow-width design allows for placement adjacent to pedestrian walkway areas. A small, unobtrusive, vegetated planter bed / filtration chamber that can also accommodates roof downspout discharges,  with (optional) side inlet/s.

Reinforced concrete (cast-in-place) units are H-10 load rated, ensuring the public's safety next to pedestrian walkways.

A single side (curb-inlet style) opening allows for maximum water infiltration into receiving trash / debris area, then infiltration into the vegetated biofiltration chambers.

A wide variety of grates are available in a multitude of finishes, insuring and enhancing the aesthetics of the finished project, (See Grate Covers / Tree Guards Sections).

"This unit may very well solve all of our filtration issues for a new hotel project in Dana Point, what an innovative design Katchall came up with, great job guys"!     Hunsaker & Associates
