What is one performance criterion that an outlet baffle screen or filter must meet?

The performance criterion that an outlet baffle screen or filter must meet is ensuring that it protects the pressure distribution drainfield discharge from plugging. This is crucial for the effective functioning of septic systems, as the filter serves to prevent larger solids and debris from leaving the septic tank and entering the drainfield. If the drainfield becomes clogged with materials that should have been filtered out, it can lead to significant system failures, including backups and contamination of groundwater.

Ensuring the integrity of the outlet baffle screen or filter is essential for maintaining the long-term performance of the septic system, as a properly functioning filter contributes to the overall efficiency, longevity, and environmental safety of the wastewater treatment process. By preventing solids from clogging the drainfield, it allows for adequate drainage and treatment of effluent, which is vital for protecting public health and the environment.
