Why Do Water Systems Use Corrosion Control?
Corrosion control keeps metals from dissolving out of pipes and plumbing into the water. The main reason is lead and copper from service lines and home plumbing. Treatment keeps a thin protective coating on the inside of those pipes.
Plants do this by managing pH, alkalinity, and carbonate chemistry, or by feeding a corrosion inhibitor, under an approved plan. Water Distribution Fundamentals covers what disturbs that coating in the pipes.
What happens at the tap depends on more than one plant number. Pipe material, existing scale, temperature, disinfectant, water age, and source blending all play a part. A steady value at the plant does not represent every tap.
Keep the approved treatment steady, check feed and results, and tell the right people about source or process changes. Do not change corrosion control to fix an unrelated complaint without review. Small changes can loosen built-up scale and release metals.
Key point: Corrosion control protects customers from lead and copper; it is a systemwide plan, not one plant number.
