Uncover hidden risks, prioritize replacements

The Problem: Lead pipes in water infrastructure pose a serious health threat. Utilities nationwide need solutions for efficient lead-line inventory and replacement.

The Solution: Geographic Information Systems (GIS) = Powerful toolkit for pinpointing lead service lines, streamlining data collection, and prioritizing replacements.

This webinar will demonstrate how:

  • GIS creates a comprehensive lead-line inventory map.

  • GPS streamlines field data collection and verification.

  • Prioritize lead-line replacements based on risk factors.

This webinar presents a crucial discussion on mitigating the health risks posed by lead pipes in the nation's water infrastructure. It introduces Geographic Information Systems (GIS) as an invaluable tool for utilities grappling with the challenges of lead service line identification, inventory, and prioritization for replacement. Attendees will learn how GIS technology can create detailed lead-line inventory maps, significantly enhancing the visibility of potentially hazardous lines.


The integration of GPS technology further streamlines the process, facilitating efficient field data collection and verification directly on-site. A major focus will be on how to utilize this compiled data to systematically prioritize lead-line replacements, taking into account various risk factors to ensure that the most critical areas are addressed promptly. This approach not only promises to improve public health safety but also optimizes the allocation of resources for utility companies facing the daunting task of updating their infrastructure.
