Lead Service Line Replacement (LSLR) Program Drinking Water State Revolving Fund (DWSRF)

1. What can the program do for you?

The Drinking Water State Revolving Fund (DWSRF), authorized by the Safe Drinking Water Act, provides low-cost financial assistance for planning, acquisition, design, and construction of water infrastructure.

The Infrastructure Investment and Jobs Act (IIJA) appropriated funds through the DWSRF for Lead Service Line Replacement (LSLR) projects and associated activities directly connected to the identification, planning, design, and replacement of lead service lines.

See the DWSRF Lead Service Line Replacement (LSLR) Program Guidance for more information.

2. Who can borrow?

Eligible applicants for the LSLR program include:

  • Existing community Public Water Systems (PWSs), including political subdivisions, nonprofit water supply corporations and privately-owned community water systems
  • Non-profit, non-community public water systems
  • State agencies

An entity's project must meet the disadvantaged criteria to receive funding under this IUP. For the SFY 2024 LSLR IUP, eligible disadvantaged communities have an Annual Median Household Income (AMHI) that is no more than 150% of the State's AMHI.

To review the new disadvantaged criteria specific to the LSLR program, review Appendix D of the 2023 LSLR IUP.

3. What types of projects can I use LSLR funding for?

For a project to be eligible for LSLR funding, it must be otherwise DWSRF eligible, and be a LSLR project or associated activity directly connected to the identification, planning, design, and replacement of lead service lines. Some examples of eligible projects are:

  • Development or updating lead service line inventories, including locating and mapping lead service lines.
  • Complete removal of lead service lines (public and privately owned portion) and replace with pipe meeting requirements established under 40 CFR 143 and complies with state/local plumbing codes and/or building codes.
  • Non-routine lead sampling (not for compliance purposes) as part of the LSLR project.

Entities may also include a request for reimbursement for eligible initial service line inventory activities that were required to comply with the EPA's Lead and Copper Rule Revisions. However, the activities must have been performed in accordance with all DWSRF program requirements to be reimbursed.

For a full list of eligible and ineligible project activities, please see the 2023 LSLR IUP.

4. How much funding is available?

The amount of funding available for projects under the DWSRF LSLR program for SFY 2024 will be approximately $146,246,000 (subject to change depending on IUP approval).

In SFY 2024, construction-ready projects may receive a special allocation of the funds available. Construction-ready projects have identified lead service lines ready for replacement or the system is currently replacing lead service lines. For construction-ready funds, a system still must satisfy all federal procurement requirements.

5. Are loans or grants offered?

All financing will be made at the ratio of 51% principal forgiveness and 49% loan/bond. Principal forgiveness is functionally similar to a grant, the portion of the loan is forgiven upon closing. Loans are offered at below market interest rates.

The loan portion of any project covering service line inventories will be at 0% interest, while the loan/bond financing for any planning, acquisition, design, and/or construction work will be at the DWSRF program's regular reduced interest rate.

All projects funded are considered equivalency projects, which means all federal requirements apply.

6. When can I apply for LSLR financial assistance?

To be invited for SFY 2024, entities must submit a completed LSLR PIF no later than 11:59 p.m. CST on Monday, April 1, 2024.

Initial invitations for the DWSR-LSLR SFY 2023 were sent out on November 16, 2023. At this time, TWDB is receiving and processing Intents to Apply and Applications from systems that were included in the first round of invitations. Depending on the amount of funding still available, additional projects may be invited during a 2nd round of invitations (TBD) for the DWSRF-LSLR SFY 2023.

All systems are encouraged to submit a PIF for the current round of funding (SFY2024) in case capacity has been reached for SFY2023.
