For Type 4 and Type 5 septic systems, which entity may operate the system?

• A. Public Management Entity with a Certified Operator
• B. Private Certified Operator
• C. Owner
• D. Public Utility

Answer: (A)

Type 4 and Type 5 septic systems are complex and require active, ongoing management by someone with a certified operator credential. Because they pose a higher risk to public health if not operated correctly, the responsibility is placed with a public management entity that can ensure consistent oversight, proper funding, and accountability, with the operator actually holding the certified license. This setup ensures routine maintenance, monitoring of system performance, timely repairs, record-keeping, and prompt responses to any failures. Leaving operation to the individual owner or to a private operator may lack the necessary public oversight and resources, and while a public utility can be involved in some cases, the standard arrangement for these system types is a public management entity with a certified operator.
