Meet Your LCRI Deadline with a Verified Service Line Inventory
Juno Maps helps water utilities build accurate, field-verified lead service line inventories that satisfy EPA LCRI requirements, combining GIS-based material classification, digital field tools, and regulatory-ready reporting in a single managed workflow.
What the EPA Lead and Copper Rule Improvements Require
The Environmental Protection Agency (EPA) finalized the Lead and Copper Rule Improvements (LCRI) to accelerate the elimination of lead exposure in drinking water systems nationwide. The rule mandates full identification and material classification of all service lines, mandatory replacement of all lead service lines within a decade, enhanced tap water sampling protocols, and a lower lead action level. Every community water system subject to the Safe Drinking Water Act must comply, and the November 2027 inventory submission deadline leaves limited time for systems that have not yet begun.
Read EPA Rule OverviewCritical Compliance Dates & Requirements
The LCRI establishes binding timelines. Understanding each milestone is the first step toward a defensible compliance plan.
Inventory Submission Deadline
Submit updated baseline lead service line inventories to your state primacy agency by Nov. 1, 2027.
Full Replacement Deadline
All lead service lines and galvanized-requiring-replacement (GRR) lines must be replaced by 2034.
Annual Inventory Updates
Maintain, update, and submit an annual service line inventory reflecting current material classifications and replacement status.
Minimum Replacement Rate
Replace at least 10% of confirmed lead service lines annually until the system achieves full replacement.

A Structured Path to LCRI Compliance, From Incomplete Records to Verified Inventory
Most water utilities face the same challenge: baseline records that are incomplete, paper-based, or inconsistently maintained. Juno Maps specializes in moving utilities from that starting point to a complete, field-verified, and regulatory-ready lead service line inventory. Using Smart Site Plan, our GIS-powered compliance platform, we digitize legacy records, classify service line materials, coordinate field verification, and produce the structured data exports your state primacy agency requires for LCRI submission.

Full-Spectrum LCRI Inventory & Compliance Support
From digitizing legacy utility records to field verification campaigns and state submission reporting, our team manages every phase of the lead service line inventory process.
Digitizing Existing Utility Plans
Convert legacy paper plans, hand-drawn maps, and scanned utility records into spatially accurate GIS layers that form the foundation of your LCRI-compliant service line inventory.
Historic Imagery Analysis
Cross-reference construction-era aerial imagery with current parcel data to resolve unknown service line materials, closing inventory gaps before they become compliance liabilities under LCRR classification requirements.
Digital Self-Reporting Forms
Deploy mobile-ready forms that allow property owners to photograph and submit service line material evidence directly, expanding inventory coverage without proportional increases in fieldwork cost.
Targeted Field Verification
Coordinate field inspection campaigns to physically verify, document, and classify service line materials at the curb stop or meter, with GPS-tagged findings recorded directly into your GIS inventory.
Centralized Inventory Management
Maintain a single, authoritative lead service line inventory your team can query, update, and export for annual state primacy agency submissions, replacement tracking, and public disclosure requirements under LCRI.
Common Questions About EPA LCRI Compliance
What is the EPA LCRI deadline for lead service line inventory?
Under the Lead and Copper Rule Improvements (LCRI), water systems must submit updated baseline lead service line inventories to their state primacy agency by November 1, 2027. All lead service lines and galvanized-requiring-replacement (GRR) lines must be fully replaced by 2034, with a minimum 10% annual replacement rate required in the interim.
How does Juno Maps help utilities meet LCRI requirements?
Juno Maps supports utilities through every phase of LCRI compliance: digitizing historical utility records, building GIS-based service line inventories with verified material classifications, deploying digital self-reporting tools for property owners, coordinating field inspection campaigns, and generating regulatory-formatted reports for state primacy agency submissions.
What if our utility has incomplete or paper-based records?
Incomplete baseline records are common, particularly among smaller community water systems. Our team specializes in digitizing legacy paper plans, cross-referencing historical aerial imagery, and supplementing records with field verification data to close inventory gaps, even for utilities with minimal documentation.
Which states does Juno Maps work with?
We primarily serve utilities in Delaware, Maryland, Pennsylvania, Virginia, and West Virginia, with deep working knowledge of each state primacy agency’s inventory submission requirements. We also support utilities in other states, contact us to discuss your jurisdiction’s specific requirements.
How long does a lead service line inventory project take?
Project timelines depend on system size, baseline record quality, inspection scope, and state-specific requirements. Most projects are scoped and estimated following an initial consultation. Contact our team to discuss your utility’s current inventory status and a realistic path to the 2027 submission deadline.
