Vault Biofilters
A vault-type biofilter is perfect for companies with footprint restrictions or facilities that already have catch basins. We have ample experience designing drainage using quality materials that will provide metals removals as high as our above-ground biofilters. These options save space and money for your company.
AutoGator
Our first Biofilter vault design, AutoGator, proposed that we re-engineer their outflow vault into a biochar biofilter. It was simple to install, relatively inexpensive, and produced great lab results. AutoGator not only went back to baseline status; but it is still in compliance even after California stormwater benchmarks for zinc and copper levels were cut in half in year Y2020.
Hillsboro Garbarge Transfer
We proposed a biochar biofilter vault design at Hillsboro Garbage outfall vault. Again, our biofilter vault is producing great lab results! And again, for a fraction of what a pump n’ treat would cost!
