For Type 6 systems, which option describes a valid inspection schedule?

Explanation:
Inspection frequency for Type 6 systems should scale with the system’s design daily wastewater flow. Larger flows mean more wastewater passing through the system, increasing wear, potential for failure, and the need for closer monitoring. The schedule that ties inspections to GPD does exactly that: it starts with a monthly-to-weekly cadence for smaller, lower-flow ranges and increases the number of inspections per week as flow rises, up to multiple checks for very high-flow systems. This approach balances thorough oversight with practicality, ensuring issues are detected early on systems carrying more wastewater. Other options don’t fit because they either fix the same frequency regardless of how much wastewater the system handles (too infrequent or too generic) or demand an impractical level of monitoring (daily) that isn’t aligned with typical risk-based inspection practice.
