Who is Affected by Lead Service Lines?

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 plumbing and fixtures used in some homes. Lead does not affect Green Bay homes built since 1984, and is most common among homes built before 1944.

Problem -areas

Approximately 1,100 out of 36,400 water service lines in the City of Green Bay, or fewer than 3.5 percent, 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 worked with the City of Green Bay and the Department of Natural Resources to offer grants and zero percent interest loans to help homeowners cover incurred costs. These monies are available on a first-come, first-served basis.

How can I identify the material my private-side water service is made of?

The Water Utility knows where all the lead is on the utility-owned side of the water system. And we know what type of water service line material exists for all properties in the City of Green Bay EXCEPT 360 PROPERTIES. We have reached out to these 360 property owners via a series of three postcards, several letters, door hangers, and now, via phone, to get into their homes and properties to detemrine what kind of water service line they have. If we haven't reached out to you all these ways, we know what your service line is made of. 



This video, created by Green Bay Water Utility, explains how to identify your private water service line material, and demonstrates how to test whether you have a lead pipe, copper pipe, galvanized steel pipe or plastic pipe.
