Biotreatment Soil Mix is very effective at filtering stormwater runoff before it enters our storm drains and waterways. The process of running the storm or runoff water through the Biotreatment Soil Mix allows the water to be cleaned up by the biology and filtered so pollutants and sediments are much reduced. The Biotreatment Soil Mix will support many vernal and riparian plant communities, the roots of the plants will also help clean up the stormwater runoff. The quality of water going into our streams, creeks, bay and ocean will be much improved creating a much healthier habitat for our native amphibians and fish.

Our Biotreatment Mix meets the “Soil Specifications: criteria approved by the Executive Officer of the San Francisco Bay Regional Water Quality Control Board on April 18, 2016, in accordance with Provision C.3.c.i.(2)(c)(ii) of the Municipal Regional Stormwater Permit (MRP). Meets BASMAA and SFPUC specifications.
