Tell residents only what you have confirmed, when they will hear from you next and where to ask questions. First settle who owns the water system. If a city or utility supplies the water, it issues any boil-water or safety notice. Relay that notice accurately, and confirm with the utility or your state drinking water program whether the community has notice duties of its own. If your community runs its own system and it qualifies as a public water system, federal rules set notice deadlines, including Tier 1 notice as soon as practical and no later than 24 hours for the most serious situations, and your state drinking water program decides what is required.

This article covers communication. It is not legal advice. Your state may set stricter or additional requirements.

First, know who owns the water system

Two communities with the same outage can have very different obligations.

  • Utility-supplied water. The city, county or water district owns treatment and testing. When water safety is in question, the utility decides on and issues the notice. Pass that notice on to every household, word for word, and handle anything on the community's side of the meter. Confirm in writing with the utility or your state primacy agency whether the community has any notice duties of its own.
  • Community-owned system. Some communities have their own wells and distribution lines. The EPA defines a public water system as one that provides water through pipes to at least 15 service connections, or regularly serves at least 25 people for at least 60 days a year. A community water system is a public water system that serves the same people year-round. The EPA lists mobile home parks among the service areas a water system can serve. If your system qualifies, the public notification rules apply to you as the operator.

If you are not sure which you are, your state drinking water program can tell you. Find out before an outage, not during one.

What the federal notice rules require

This applies to public water systems. If a utility supplies your water, confirm with the utility or your state primacy agency whether any of it applies to your community before you rely on the workflow alone.

Under the EPA's Public Notification Rule, violations and situations fall into three tiers.

Tier Examples from the rule Deadline Extra step
Tier 1 E. coli or fecal coliform violations, nitrate violations, a waterborne disease outbreak, or another waterborne emergency such as a significant interruption in treatment or a natural disaster that disrupts supply. Since October 16, 2024, an exceedance of the lead action level. As soon as practical, no later than 24 hours after the system learns of it Start consultation with the state (primacy agency) as soon as practical, no later than 24 hours after the system learns of it
Tier 2 Violations of a maximum contaminant level, maximum residual disinfectant level or treatment technique that do not require Tier 1, some monitoring violations the state elevates, and failure to meet a variance or exemption As soon as practical, no later than 30 days after the system learns of it A posted notice stays up while the problem lasts, and at least 7 days
Tier 3 Monitoring and testing procedure violations not in Tiers 1 or 2, operating under a variance or exemption, and certain other situations listed in the rule No later than one year after the system learns of it, repeated yearly while it continues Community water systems may use the annual water quality report (Consumer Confidence Report)

The tier assignments for specific violations are listed in the rule itself, and your state may require more. EPA publishes notice templates for systems to customize, and its handbook explains which delivery methods count for each tier. Use those templates rather than writing regulatory language from scratch.

Not every outage is a Tier 1 situation. Whether a break or a loss of pressure needs a notice, and which kind, is a question for your state program. Ask it as soon as you confirm the problem. The 24-hour limit is the latest a Tier 1 notice and consultation can happen, not a window for deciding.

A communication workflow for any outage

The steps below work for planned shutoffs, unplanned breaks and regulatory notices. For regulatory notices, the content comes from the template and your state, and these steps handle delivery.

Step Owner What happens Output
1. Confirm facts Maintenance lead Which streets or lots are affected, whether water is off or unsafe, cause if known, and an honest restore estimate or "not known yet" Fact sheet with a timestamp
2. Classify and ask Community manager Planned work, unplanned interruption, or a water-quality notice from the utility or state. For any unplanned loss of water or pressure, ask the utility (or, for your own system, the state program) right away what residents should do now Category that decides the template, plus any instruction to relay
3. First notice Community manager Send what is known, what is not, what residents should do, the next update time and one contact route First notice sent and logged
4. Reach everyone Office staff Text or email, plus printed notices at mailboxes, the office and affected doors for residents without phones Delivery list checked off
5. Update on schedule Community manager Send an update at the promised time, even if nothing has changed Updates logged with times
6. Restored, then all clear Community manager Announce restored supply as its own message. Say the water is safe to drink, or that a notice is lifted, only when the utility or state says so Restoration and all-clear logged separately
7. Review Manager and maintenance lead What happened, which residents were missed, what to change Short after-action note

The promised update time does the most work. Residents call the office when they do not know when they will hear more. A message that says "next update at 6 p.m." answers that before they pick up the phone.

What every notice should say

Keep each notice short enough to read on a phone. A simple structure:

  1. What is happening. "Water is off on Oak Lane and Pine Court (lots 30 to 52) because of a broken main."
  2. What we know and do not know. "The crew is on site. We do not have a repair time yet."
  3. What to do. For a regulatory notice, the instructions come from the utility or state template. Never improvise boil-water guidance.
  4. When we will update you. "Next update by 4 p.m. today."
  5. Where to ask. One phone number or one text line. Ask residents not to rely on social media posts.

Translate notices if residents speak another language at home, and keep a large-print copy for posting.

Checklist for the next outage

Build this before you need it.

  • Written answer to "who owns our water system?" with the utility or state program contact
  • Current contact list for every household, with a note on who has no mobile phone
  • Map or list of which lots are on which water lines or valves
  • Templates for planned work, unplanned interruptions and all-clear messages
  • For public water systems, the EPA or state Tier 1 template saved and filled in with your system details
  • Printed notice template and a place to post it
  • One named person who sends notices, and one backup
  • Log format: time, message, channel, who sent it
  • Optional: translated templates for languages spoken in the community

A worked example (hypothetical)

This timeline is invented to show the steps. The community, times and details are not real.

A 64-lot community on city water has a main break inside the community on a Saturday at 2:10 p.m.

  • 2:25 p.m. The maintenance lead confirms that lots 30 to 52 have no water. Lots 1 to 29 and 53 to 64 have normal pressure. The manager calls the city, which confirms the break is on the community's side of the meter. On the same call, the manager asks whether the pressure loss calls for any precaution and what residents should do now.
  • 2:40 p.m. The manager texts all 64 households: which lots are affected, the city's instructions for now as the city gave them, that repair time is not known yet, and that the next update will come by 4:30 p.m. If the city had not answered yet, the text would say that guidance is pending instead of guessing. The office posts printed notices at the mailboxes and tapes notices to the doors of three affected households with no mobile phone on file.
  • 4:30 p.m. Update: the plumber arrives at 5:00, and the estimated repair is three to four hours. Next update by 8:00 p.m.
  • 8:00 p.m. Update as promised: the repair is still in progress and water is not back yet. The manager repeats the city's current instruction and says the next update will come by 9:00 p.m., or sooner if water returns.
  • 8:05 p.m. Water is restored to lots 30 to 52. The manager texts that supply is back and repeats the city's current instruction. Restored supply is not the same as safe to drink. If the city has issued an advisory, the all-clear goes out only when the city lifts it, in the city's words.
  • Monday. After-action note: two residents said they missed the first text because their numbers were out of date. The contact list update is added to the annual lease renewal.

Common problems and fixes

Symptom Likely cause Fix
The office phone rings nonstop Notices had no next-update time Put a specific time in every message and keep it
Rumors in a community social media group No single source of updates Name one channel as official in every notice
Some residents never heard about it Text-only notices, or out-of-date contacts Add printed notices and keep a no-phone list
Residents get conflicting information Several staff posting updates One sender, with a backup
A boil-water notice was "lifted" too early The community acted without the utility or state Only relay all-clear messages from the authority that issued the notice

Where Propty fits

During an outage, the phone can become the bottleneck. Propty's manufactured home park page describes answering calls day and night with an approved greeting, holding the conversation in Spanish when a caller speaks Spanish, and texting back missed callers. Anything it tells callers would come from the information you give it, so update it with the same confirmed facts and next-update time you send residents. These descriptions come from Propty's public pages as checked on 2026-10-14. They are not a test of the live product. What is available for a property depends on setup and connected services, so confirm current behavior in a demo before relying on it.
