At BIOROCK, we use revolutionary techniques to ensure all of our sewage treatment plants are non-electric, have a low carbon footprint and call for minimum annual maintenance. As our innovations ensure that nature runs the operation, you’ll save big bucks not only on maintenance, but electricity too. We believe in our products and trust them. This is why we provide a 10-year warranty on the media and a 25-year warranty on the tanks. This proves that you can rely on our products to work optimally for years to come.
