Below ground and out of sight
Waterloo Biofilter Baskets are constructed of a rigid steel mesh that is coated for corrosion protection. Baskets are filled with the patented Waterloo Biofilter filter medium, shipped to site, and placed in a concrete or fiberglass tank. Baskets are sized for locally available tanks to reduce costs for the installer and homeowner. Treated effluent is pumped from the Biofilter treatment unit to a small disposal bed, leaching field or trench. Basket Biofilters operate in recirculation mode for increased nitrogen removal. The only moving parts are two high-quality, energy efficient 1/2 horsepower effluent pumps that operate intermittently throughout the day.
