Lead Service Line Replacement Funding Program
The Infrastructure Investment and Jobs Act (IIJA) of 2021 provides funding through the Drinking Water State Revolving Fund (DWSRF) for lead service line (LSL) identification and replacement. California received $250 million in FY 2022 and $29 million in FY 2023, and California can apply for further allotments in future years if additional need is identified. Funding is available to community water systems and non-profit non-community systems to complete LSL inventory and replacement. The DWSRF Intended Use Plan (IUP) and the Lead Service Line Replacement Funding Supplemental Intended Used Plan provide guidelines and funding criteria and will be updated annually.

Frequently Asked Questions
Read the answers to eight LSLR Funding Program Frequently Asked Questions.
How to Apply
Eligible applicants can submit the Lead Service Line Replacement Program Application packages (see the “Application for Lead Service Line Funding” appendix of the DWSRF Policy) via the Financial Assistance Application Submittal Tool (FAAST)
It is recommended that applicants use the Division of Drinking Water (DDW) inventory template that contains the minimum information required to comply with the LCRR. The inventory template can be used as a deliverable under an inventory project or as part of the application for a replacement project.
Eligible Entities
Community water systems and non-profit non-community water systems.
Funding Eligibility
Water systems serving disadvantaged communities are eligible to receive up to 100% principal forgiveness. Water systems serving non-disadvantaged communities are eligible to receive loan at zero percent (0%) interest rate. Loan funding agreements to non-disadvantaged community water systems may include the possibility of PF for work done in a disadvantaged community within the service area, depending on the demand for funding.
Project Eligibility
All projects funded under the LSLR funding program must comply with all DWSRF eligibility requirements. Replacement of a lead service line must replace the entire lead service line, not just a portion, unless a portion has already been replaced, is concurrently being replaced with another funding source, or an exception applies.
Some examples of eligible projects and activities include the following:
- Complete removal of lead service lines (public and privately owned portion) and Galvanized Required Replacement (GRR).
- Removal of lead or galvanized goosenecks, pigtails, and connectors.
- Replacement of curb stops, curb stop boxes, and other service line appurtenances that are removed as part of full LSLR.
- Site restoration, including landscaping, sidewalks, driveways, etc. if the removal was necessary to replace the lead service line.
- Permit fees if the fees are normal, required, and specific to the LSLR.
- Temporary pitcher filters or point-of-use (POU) devices certified by an American National Standards Institute accredited certifier to reduce lead during or for a short time period after LSLR projects.
- Development or updating of lead service line inventories, including locating and mapping lead service lines.
- Methods of investigation to develop inventories could include visual observation, water quality sampling (non-compliance), excavation, vacuum or hydro-excavation, statistical analysis, or other emerging technologies.
- Planning and design for infrastructure projects listed above.
- Non-routine lead sampling (if not for compliance purposes) as part of a LSLR project.
