Of U.S. drinking water violations are caused by missed or late samples due to changing requirements, scattered data, and manual tracking tools that can't keep up.
120Water's Sample Manager solves 
these challenges in one platform.

From collection to compliance – all in one place.

Managing the complexities of LCRI doesn’t have to be complicated. 120Water gives you the platform and the automation you need to keep programs moving and communities informed.

Unknown service lines

Use the unknown count from your current inventory, not the one you submitted in 2024 if you've verified lines since.

Cost to verify one line

Include crew time, equipment and site restoration, or your contractor's per-line price. If your state requires both sides of the line to be checked, count both.

Lines verified per week

Use the pace your crew can hold over months, accounting for weather, other work orders and time off, rather than your best week.

Frequently Asked Questions

What is required in the 2027 LCRI service line inventory?

By 2027, systems must classify all service lines as lead, non-lead, galvanized requiring replacement, or unknown. These classifications should also include connectors and goosenecks. If you aren’t sure about meeting these requirements, reach out to us! We’d be happy to help guide you through the process.

What is the due date for annual resident notifications?

Notifications must be sent annually by July 1 unless state rules specify otherwise. With 120Water, we help automate your compliant letters and track delivery.

What counts as an “unknown” service line under LCRI?

Lines without a confirmed material classification must be marked as unknown. 120Water’s water compliance platform helps document historical data, verify materials, and manage field inspections.

What states allow statistical approaches to verification?

While state rules differ, 120Water guides your team through which statistical methods are permitted and how to apply them correctly.

What records can be used to classify service line materials?

Approved records include construction codes, plumbing permits, tap cards, installation records, billing records, and previous sampling/inspection data.

What is the lead ban date and how does it affect inventory?

The 1978 lead ban marks a key cutoff for determining probable lead materials. Homes built after the ban are more likely to have non-lead lines.
