The purpose of Pretreatment and Source Control is to manage industrial wastewater dischargers to enhance the ability of Agency’s water recycling plants to comply with National Pollutant Discharge Elimination System (NPDES) requirements; to protect the public, the environment, Agency personnel and facilities; and recovery of wastewater treatment operations and maintenance costs.

The wastewater collections system is comprised of the Regional Sewerage Systems which conveys wastewater to the Agency’s regional water recycling plants or to the Non-Reclaimable Wastewater System (NRWS) that exports industrial wastewater laden with high strength and not suitable for recycling at this time.
