Corrosion control at a potable water filtration plant incorporates many corrosion industry standard practices with needs and circumstances particular to the water works industry. The Metropolitan Water District of Southern California has successfully mitigated corrosion at its water filtration plants for 50 years through efficient use of coatings and cathodic protection, and is incorporating modern non-destructive testing techniques including ultrasonic and acoustic emission testing. Research is being conducted to address the corrosion implications of changing treatment techniques including treatment with ferric chloride and PEROXONE.
