How often must Type 4 systems be inspected?

Type 4 septic systems, often referred to as advanced treatment systems, require more frequent inspections as part of their maintenance to ensure they operate effectively. The recommended frequency of inspection for these systems is every 6 months. This regular inspection schedule helps identify any potential issues early on, allowing for timely maintenance and preventing more severe problems that can arise from neglect. By adhering to this six-month inspection interval, homeowners and operators can ensure that the system remains compliant with local regulations and continues to protect public health and the environment efficiently.
