Who is Affected by Lead Service Lines?

Pie -chart

None of the water mains in the Green Bay Water Utility system are made of lead. The only lead piping is found in a minimal amount of older water service lines in Green Bay, which are the pipes that run from the main water line in the street directly to a house. Lead may also be found in plumping and fixtures used in some homes. Lead does not affect Green Bay homes built since 1984, and is more common among homes built before 1944.

Problem -areas

Approximately 1,700 out of 35,600 water service lines in the City of Green Bay, or less than 5%, are affected by lead. Half of a property’s service line is owned by the utility, and the other half is owned by the property owner, separated by the curb stop (see above illustration). If both halves are made of lead, it is important to replace them at the same since replacing only one may result in more lead entering the home. Therefore, replacing these lines requires a collaborative effort between our customers and our utility.  

Properties with both utility- and privately-owned lead service lines will also require additional planning and funding since property owners are currently required by law to pay for the replacement of their service lines. The water utility is working with the City of Green Bay to form grants and zero percent interest loans to help homeowners cover incurred costs.

What are the hazards associated with lead in water?

Lead can pose a significant risk to your health if too much of it enters your body. Lead builds up over many years and can cause damage to the brain, red blood cells and kidneys. Lead exposure may also cause slight increases in the blood pressure of some adults. The greatest risk is to young children and pregnant women.
