Big Fish Environmental

Big Fish Environmental designs and builds low-cost, environmentally sustainable, septage and high-strength waste processing facilities.


The results from a 13-month verification test performed by NSF International under the US Environmental Protection Agency (EPA) ETV Program’s Water Quality Protection Center are a strong endorsement for Big Fish Environmental’s waste processing system. According to Tom Stevens, an NSF Water Quality Protection Center Manager, the Big Fish Environmental system “provides a viable technical solution to the pervasive problem of septage treatment at wastewater treatment plants. The Big Fish System demonstrated effective treatment of septage and high strength wastewaters, making the effluent treatable at a wastewater treatment plant, and making beneficial and sustainable use of recovered biosolids.”

The comprehensive NSF assessment of the system’s performance level was performed at the Big Fish Environmental’s facility in Charlevoix, Michigan. During the verification, Big Fish’s treatment system processed septage and high strength wastewater from a wide range of sources including residential and commercial septic tanks, portable toilet waste, fruit processing waste, municipal wastewater treatment plant secondary sludge, and commercial wastes containing fats, oils and grease. In every instance, the Big Fish process handled every material with ease. See the NSF test results, and other test results by clicking on the links below.
