Lead Service Line Inventory Grant

The first phase of this IIJA funding opportunity is to assist PWSs with meeting two important deadlines in the LCRR. Both the LSL inventory and replacement plans were due October 16, 2024. Preparing these inventories and replacement plans is the first step to identifying critical locations with potentially high drinking water lead exposure. These documents also allow the PWSs to target communication with impacted residents, reassess their sampling locations, and begin planning to conduct full LSLRs.

Eligible grant entities will complete a grant application within SWIG’s Grants Management System (GMS). The grant application will establish the items needed for a complete application. All grant applications must be submitted by the announced deadline.

Eligible grant applicants include cities, counties, utility districts, and water authorities that own or operate a public water system. Grant applicants are responsible for grant oversight and monitoring of activities. Grant applicants are also responsible for submitting progress updates as requested by SWIG and managing the grant contract scopes of services.

This grant will assist communities in updating their LSLIs, developing replacement plans, and advancing the planning and design of future full LSL replacement projects. The goal is to position PWSs to meet regulatory requirements and establish a pipeline of LSLR projects eligible for financing through SRF loans.

Division of Water Resources’ Compliance and Enforcement Program (DWR-CE) has established an LSLI Fillable Excel Data Sheet. When reviewing the eligible activities below, it is highly recommended to reference this datasheet. USEPA has released additional guidance for developing and maintaining a Service Line Inventory. This guidance should be used to determine the level of effort and resources needed to update the LSLI. Since LSLI is the foundation of the LCRR, communities must update unknowns with their current LSLI and/or develop replacement plans for known lead with this funding opportunity.

This grant opportunity can cover the costs associated with the planning, creation, investigation, and revisions to the LSLI. Additionally, applicants should refer to the eligibility guidance for Drinking Water State Revolving Fund and BIL SRF Memorandum for other eligibility requirements. The requirements to conduct LSLI activities under this grant are further detailed in the grant manual.

o SWIG has allocated $ 7,475,847.92 for this LSL grant. Grant award maximums are $250,000 per applicant. The designated funding allocations will be the dollar amount that can be used to reimburse eligible LSLI projects once the community receives a fully executed grant contract. Grant applicants must consider proposal budget maximums and match requirements when developing and submitting proposals. A proposal’s total project budget is the sum of the grant award plus their match. Match will be applied to the total project budget for each reimbursement request.

Match is required for all LSLI grants. Each recipient is anticipated to contribute a matching ranging between 15%-25% of the total project cost. Match amounts are based on the 2024 Ability To Pay Index (ATPI) for the project area served (city or county scale).

On August 6, 2025, TDEC hosted a virtual webinar for the LSLI program to discuss the grant application process for potential applicants.
