We do not have a state approval at this time, however, the Enviro-Septic® System may still be approved for use in certain circumstances. If you are looking to have an Enviro-Septic® System designed to replace a malfunctioning system, you would only need to contact your local engineer or Board of Health for approval. For a newly constructed Enviro-Septic® System, your designer must submit the design as a Treatment Works Approval (TWA) to the Bureau of Nonpoint Pollution Control for approval. If use of Advanced Enviro-Septic™/Enviro-Septic® is granted, product certification is required. We welcome you to check our website periodically for approval status updates.
