Map information
The data used to develop the map is based on verified records, recent inspections and the year a property was constructed. Material types shown include:
Lead: Some or all of the service line is made of lead.
Galvanized steel: Some or all of the service line is made of galvanized steel. Aurora Water is currently determining whether galvanized service lines have ever been connected to a lead pipe.
- Lines connected to a lead pipe must be replaced and are designated as Galvanized Requiring Replacement (GRR). Under the EPA’s Lead and Copper Rule Improvements only GRR service lines must be replaced.
- Galvanized steel lines that have not been connected to a lead pipe do not pose a health risk and will not be replaced. These lines are categorized as non-lead.
Not lead: The service line is known to be copper, plastic or galvanized steel that has never been connected to a lead pipe.
Unknown: When records are missing or unverifiable, or there have been no documented inspections.
- Why are some service lines categorized as "unknown"? In Colorado, properties constructed in 1960 or earlier sometimes installed lead or galvanized steel water service lines. Unfortunately, records stating the type of service line material that was used often do not exist or cannot be verified. Currently, Aurora Water has more than 5,000 service lines marked as unknown, which means these lines still need to be inspected to determine what the service line is made of.
