Lead service-line records

All the water district main lines to meter pit are copper. The builder of your residence may have used a different material.

The District and 120Water are continuing EPA Lead and Copper Rule inventory work. Customers who receive a door hanger should email a photo of the water line entering the home, including the service address. Customers unable to email a photo may call the office to arrange for a service employee to bring a District tablet; the employee will not enter the residence to take the photograph.
