What does it mean if I receive a notice that my service line is “GRR”?

When the City of Sonoma performed site inspections, we found that your water service from the meter to your home to be galvanized iron. Galvanized iron is a material that has the potential to absorb lead over time.

We currently do not have any city-owned lead water services within the City of Sonoma. Records show that all city-owned water services installed after the adoption of current standards were of a material other than lead, but for water services installed prior, these services are not guaranteed to be non-lead. Because we cannot guarantee the city-owned portion of the service was never lead, your water service is categorized as “Galvanized Requiring Replacement” and your water service line will need to be replaced.

Currently, the EPA and California Department of Drinking Water are working on guidelines to inform and assist homeowners on the replacement of these galvanized iron services. We are currently working on the City of Sonoma’s GRR program to ensure that homeowners have all the relevant information, guidance and potential financial assistance to help homeowners through the process of replacing their galvanized iron service lines.
