Water systems
EPA’s revised water quality report rule starts January 1, 2027. Lead service line notices and emergency response plans have their own dates. Celsari prepares these documents from your system’s own data, in plain language and accessible formats, and leaves every decision to your certified operator.
Next date: December 31, 2026Emergency response plan certification for systems serving 3,301 to 49,999 people
Each one publishes a water quality report every year, tells customers about lead service lines and keeps an emergency plan. For a small system, that work lands on one operator who is also running the plant.
Count of active community water systems with a local government owner in EPA’s ECHO database, October 2026. The count includes water districts as well as towns.
These come from EPA’s rules. Your state’s drinking water program may add its own requirements, and we check the current wording before every engagement.

Due July 1 every year
The revised rule adds a summary at the start, clearer data tables, and a duty to give the report in an accessible format on request. We build the report from your lab results, add the required state wording, and produce a tagged PDF and a web page.
Annual, and by November 1, 2027
Customers on lead, galvanized or unknown lines must be told. We turn your inventory into mailable notices and an accessible public inventory page, and draft your replacement plan from your records. Your system decides what each line is made of.
Certify by December 31, 2026, for systems serving 3,301 to 49,999
Only a certification goes to EPA, but the plan must exist and be kept for five years. We organize your plan into the form EPA’s template expects and track what is finished. Risk and security judgments stay with you.

Send us your water system ID. We look up your public EPA record and tell you which of these apply and when.
We quote a price in writing and send a short checklist of what we need, such as your lab reports and your state violation log. You upload files to a private page. We never ask for your logins.
We send finished documents for your operator to review. Nothing is released until your operator signs off.
We do not test water, and we do not decide what material a service line is made of. We do not certify anything to EPA or to your state, and we do not guarantee that a report or plan will pass a state review. The numbers and statements in every document are your system’s, confirmed by your certified operator.
If your state publishes a template or your state program does the data work for you, we will tell you honestly whether we can add anything.
Templates are free, and some systems use them well. The work is assembling your data into the template, writing it in plain language, producing an accessible version, and checking that every required item is there. If you can do that comfortably, you may not need us.
No. Your operator exports your sample results or sends your lab reports. We never ask for logins.
No. They are separate duties. The inventory records what each line is made of. The notice tells customers with lead, galvanized or unknown lines. We prepare both from your records.
No. The risk assessment comes first, and the plan must be certified within six months of it. We work on the plan document. The assessment itself rests on your own judgment of risks.
No. We prepare documents. Your operator, your state program and your counsel decide what to publish and certify.
Send us your water system ID. We will tell you by email which of these apply and when. There is no cost and no obligation.
