In this section, you can find all requirements related to consumer and public notifications related to service line inventory and replacement.

Public notification for consumers served by lead, GRR (Galvanized requiring replacement) or unknown service lines

All systems with lead, GRR (galvanized requiring replacement), or unknown service lines must send a public notification to all consumers served by the said service lines by Dec. 1 annually. The notification must be repeated annually until all lead and GRR service lines are replaced and the material of all unknown service lines is identified.

Find templates on the Service line material notification letter page

Certificate of Delivery for public notification

If your system sends public notifications (for lead, GRR, or unknown service lines), you must submit a Certificate of Delivery Form to the Division of Drinking Water (DDW).

The current annual deadline is July 1.
Starting in 2028, the deadline will change to January 30.

Submit the Certificate of Delivery form

Disturbance notification

If your water system disturbs a lead, GRR (Galvanized Requiring Replacement), or unknown service line, you will need to provide consumers with a Disturbance Notification.

Mandatory date: This rule goes into effect on November 1, 2027, as part of the LCRI (Lead & Copper Rule Improvements).
We strongly recommend providing these notifications now ahead of that date to protect consumers and prepare for the new rule.

See our Disturbance Letter Template

Public notification required for violations related to inventory submissions

If systems fail to submit their inventories to the Division of Drinking Water and receive a formal violation, they are required to distribute a public notification informing their consumers that a violation was received.

See other educational material requirements (EPA)

(opens in a new tab)

The final LCRI requires all water systems to validate a subset of non-lead service lines in their inventory to increase accuracy of inventories. If a service line is listed as non-lead in the inventory, it must be included in the validation pool unless:

It was installed after April 1989
It was previously lead or GRR and has been replaced
It was physically verified in the field at two points (one point for the customer owned side and one point for the system owned side)
Due Date: Nov 1, 2034
EPA’s Fact Sheet for Inventory Validation

There are three options for funding assistance that you can choose from based on your system’s needs.

Inventory and field verification

Funds may be used for planning efforts associated with service line inventory and replacement identification efforts.

SSAP (small system contractor assistance program)

Community water systems serving a population <10,000
No-cost assistance completing a service line inventory and replacement plan through Sunrise Engineering.
If a small community water system is at the beginning stages of the inventory processes, or needs help with field investigation, mapping software, or next steps, this program may be a better fit.

Disclaimer: Submitting this application is NOT a guarantee that any funding requested will be provided. Systems that have received assistance through the small systems contractor assistance program or have previously received funding through the Expedited Funding will not be eligible for additional funding through this application. The Division of Drinking Water will review applications and make final decisions with regard to eligibility and award approval.

Expedited approval funding

All Community and non-transient noncommunity public water systems
Funding for up to $100,000 is provided as either 0% interest loans or grants. Systems are only eligible for grants if they meet the division’s hardship criteria.
Recommended for water systems with staff that can complete inventory investigations or are already working with a consulting firm.

Need more than $100k?

Systems seeking financial assistance greater than $100k should apply for assistance through the SRF program (detailed in the SRF section below).

Inventory and Replacement

Funds may be used for construction and/or planning efforts associated with service line replacements and inventory identification efforts.

SRF (State Revolving Fund)

We have funding allocated for service line replacements and help completing your inventory, through our State Revolving Fund (SRF).

Hurry! This funding is only available for a limited time.

Is your water system eligible?

Financial assistance in the form of grants and loans: Awards have ranged from between $100,000 to $27 million.
Funds for construction and/or planning projects come as low-interest loans (typically below market rate, 20-39 years ) and/or grants.
For grant qualifications and hardship criteria, see State Revolving Fund (SRF): Drinking Water

Systems who already received expedited funding

Participants in the Expedited approval funding program (detailed in the section above) may apply for additional financial through the State Revolving Fund (SRF) so long as they do not exceed $100k in total assistance from the Division of Drinking Water.

If you need additional funding, reach out to the SRF team at [email protected].

In the email:

Request an amendment to your current agreement for additional funding.
Provide an estimate of how much additional funding is needed. The max allowed under expedited funding is $100,000, which includes the work and pay requests already submitted.

What is the difference between the Small Systems Assistance Program (SSAP) and Expedited Approval Funding programs?

Water systems may only receive support from one of these two programs.

Who can apply?

Expedited Approval Funding

All Community and non-transient non-community public water systems

Small Systems Assistance Program

Community water systems serving a population ≤10,000

What assistance is provided?

Expedited Approval Funding

Funding is provided as either 0%interest loans, grants, or partial grant and loan.

Small Systems Assistance Program

Assistance completing a service line inventory and replacement plan through Sunrise Engineering at no cost to the water system.

Which program is the best fit for your water system?

Expedited Approval Funding

If a water system has staff that can complete inventory investigation or is already working with a consulting firm, this program may be a better fit.

Small Systems Assistance Program

If a small community water system is at the beginning stages of the inventory processes, or needs help with field investigation, mapping software, or next steps, this program may be a better fit.
