Lead Service Line Replacement

The Environmental Protection Agency established the Lead and Copper Rule to protect public health and reduce exposure to lead and copper in drinking water. The most common sources of lead in drinking water are lead and galvanized steel pipes, and brass or bronze faucets and fixtures. According to the California State Water Resources Control Board, Division of Drinking Water, no lead water service lines are currently identified in Orange County. Water service lines are the pipes and joints that connect the water main under the street to the plumbing in your home.

Lead-containing pipes and fixtures on the privately-owned side of the property line may exist. Pre-2010 plumbing fixtures may contain lead and homes built during the 1960's and earlier may have galvanized water pipes that include lead.  

Water utilities are not responsible for replacing private service lines and plumbing fixtures owned by the homeowner or by customers served by private wells.
