Effluent Disinfection

The effluent must be disinfected to protect health. Effluent disinfection policy is issued through the Clean Water Act, State Water Code, Health and Safety Code, and other laws. The plant has been given daily limits, which are necessary for protecting human health, preventing fish kills, or preventing mortality to aquatic organisms. Below are summaries of relevant disinfection provisions of the NPDES permit. Effluent disinfection is a must. Enterococci effluent limits reflect the best bacteriological protection parameter for lightly used saltwater areas, and it has been chosen as the bacteriological parameter for the plant's effluent disinfection. The bacteriological standard had been total coliform prior to the 2003 permit.
