Interpretation

This system reported no lead or unknown service lines in its inventory. Note: the inventory covers the utility's pipes up to your property line; your home's internal plumbing may still contain lead if your home was built before 1986.

The service line inventory covers pipes owned and operated by the water system, typically from the water main to the property line. Household service lines on the customer's side of the meter are the homeowner's responsibility and may or may not be included depending on the system and state law.
