What is being discharged into the ocean?

The Ocean Outfall allows for the disposal of reverse osmosis concentrate (i.e. concentrated "purple pipe" water that is typically used for irrigation) generated by the new Advanced Water Purification Facility (AWPF), diverts wet weather flows that exceed AWPF treatment capacity, and provides an emergency backup disposal in case the AWPF is offline. All discharge from the outfall must comply with permits that the Los Angeles Regional Water Quality Control Board will issue.  

The discharge permits require the water quality discharged be protective of both aquatic and human health.
