The Roswell Water Utility has a comprehensive Corrosion Control Program to help prevent plumbing materials such as metals from breaking down into drinking water. In order to prevent lead from dissolving into water from lead service lines/laterals or home plumbing, Roswell adjusts the water’s chemistry at the treatment plant. This process is known as corrosion control. These techniques include treating the drinking water to reduce its ability to carry lead and copper from the plumbing system to the faucet.
We sample water at homes considered to be high risk in order to ensure our corrosion control remains effective. Although corrosion control can reduce risks, the best way to assure your home is safe from lead exposure through water is to remove all of the potential sources of lead.
To protect water consumers from lead and copper contamination that could occur from their home plumbing systems, public water systems are required to use “optimized corrosion control” techniques under the Lead and Copper Rule.
