PRETREATMENT PROGRAM

Objective
The objective of the Alexandria Sanitation Authority's Pretreatment Program is to prevent the introduction of pollutants that would interfere with the treatment plant's operation, pass through the plant and interfere with the aquatic life of the receiving waters, interfere with the reuse of Biosolids, or adversely affect worker health and safety. Our objectives are met by evaluating the wastewater of new and existing facilities, through surveys and/or issuing wastewater discharge permits, monitoring permitted industries by regularly sampling wastewater discharge and conducting facility inspections.
