Before an Event: Organizing for Drinking Water Advisories

Conduct an Assessment

Understanding your system's operations, vulnerabilities, stakeholders, partners, and audiences is an important first step in your planning efforts. Begin by evaluating the following:

Icon Key

tool icon Tools and Templates

resources icon Resources

  • Existing relationships among partners, including public health, public safety, schools, businesses, and local government. See Table 1 for examples.
  • Internal and external audiences and stakeholders.
  • Information needs of different audiences.
  • Existing communication plans and resources (e.g., bill inserts, Consumer Confidence Reports, media contacts).
  • Skills, technologies, staff, time, and money available to support an exchange of information with target audiences and agencies. See Table 1 for examples.
  • Resources for public outreach, such as Reverse 911 or e-mail alerts.
  • Existing requirements set by state or local agencies or by the water system’s governing body.
  • Threats and infrastructure vulnerabilities.
  • Emergency response plans (ERPs).

Gap Analysis

Once you've conducted the assessment, it is important to identify the gaps and additional resources needed to meet responsibilities for issuing drinking water advisories.

Review Regulations and Guidance 

Primacy Agency

Each state that has primacy has specific regulations for public notification and information sharing. Local public health and water systems personnel need information for a 24/7 point of contact at the primacy agency.

For information on state-specific contact information, regulatory requirements, guidance, and templates see the SDWA Primacy Agency Finder from the Association of State Drinking Water Administrators (ASDWA). See Appendix B: Online Resources, Primacy Agency.resource icon

Know Your Primacy Agency

Every state is unique. Know your state SDWA primacy agency’s practices, communication channels, and responsibilities related to drinking water advisories.

Federal Guidance

There is federal guidance for developing public notices under the Safe Drinking Water Act (SDWA). Resources are also available from the Environmental Protection Agency (EPA):

Consult Strategic Communication Plan

A strategic communication plan is the foundation for decision-making and resource allocation, both ongoing and in times of crisis.

A strategic communication plan helps a water system prepare to issue a drinking water advisory by identifying ahead of time:

Where to Find Helpresource icon

If your water system does not have a strategic communication plan, see Appendix B: Online Resources, Risk Communication for more information that may be helpful in developing one.

  • Audiences and stakeholders.
  • Critical issues for the water system (e.g., risk, safety, quality, infrastructure).
  • Points of integration for operations and communication SOPs.
  • Communication objectives (e.g., information, preparedness).
  • Strategies to accomplish objectives.
  • Actions required to carry out the strategies.

See Information for Communication Planningresource icon [DOC - 1 page] for more information.

Effective Risk Communication

Drinking water advisories are a form of risk communication. The protocols for issuing an advisory must effectively describe:

  • When to distribute an advisory (and when not to).
  • What information to provide.
  • Who is(are) the specific audience(s) for that event (including susceptible populations).
  • How to recognize and communicate the conclusion of the event.
  • Where to distribute messages.
  • What actions must be taken.
  • Why these actions must be taken.

For more information on effective risk communication, see Appendix B: Online Resources, Risk Communication.resource icon

Plan for Media Activities

Successful advisories rely on multiple types of communication. Door hangers, websites, automated messages, and other methods of communication must be combined for an effective drinking water advisory. The media is a primary channel for public notification and is critical to issuing an advisory.


Ask media outlets about their timing. How long will it take them to post and announce information on websites and announce on television? Also ask how they would use maps and graphics to show the advisory area.

Planning for media activities can improve implementation of the advisory. Scope, scale, and severity determine the level of media involvement— the larger the event, the larger the media effort. Factors to consider include the following:

  • Timing: Consider the operations of your local media. Many media outlets are not able to respond on weekends or after hours. Contact local media outlets to understand their staffing, hours, or other limitations. Plan appropriately for media outlets and communication channels. For example, if an advisory is issued during business hours or commuting times, radio reaches homes, offices, and cars.
  • Audiences: If an advisory covers a wide area, use a media release to multiple outlets. Smaller areas may call for use of specific media channels as well as other methods of communication. Audiences with special needs, such as a large population of people who speak little or no English, are part of the decisions about media, including ethnic media. See the Communicating with Susceptible Populations Worksheettool icon [DOC - 5 pages] and Appendix B: Online Resources, Risk Communication.resource icon
  • Channels: Identify the media outlets that cover specific areas of the water system service area and the region. In rural areas, television news may come out of a large urban area far away. Partners and their communication networks will have additional information about communication channels. Identify criteria on which to prioritize media outlets based on the scope, scale, and severity of the situation. For example, if an advisory is issued during working hours, radio, e-mails, and news websites may be the most immediate and viable outlets to use to distribute the message to the working public.
  • Media Messages: Use the Message Mapping Templatetool icon [DOC - 1 page] and Sample Message Maptool icon [DOC - 1 page] or the Single Overriding Communication Objectives (SOCO) Worksheettool icon [DOC - 2 pages] to prepare press releases and statement templates specific to the water system and different scenarios. These materials can be generalized and put into electronic or paper formats. Insert the prepared materials into emergency response plans (ERPs) and protocols.
  • Approval: Note the procedures on how media materials will be reviewed and who will approve them. Work with partners in the communication network and understand their approval process.
  • Other Information: Include external sources of additional information in media materials. Contact names and numbers for primacy agencies and local public health departments are good sources for reporters. Links to primacy agencies and health departments can be added to media websites to help answer customer questions. Work with partners to identify additional information sources. See Appendix B: Online Resources, Risk Communication.resource icon

Small System Note

If a press list or wire service is not available, work with partners and local government to set up access for communicating advisories to the media.

Designate and Train Spokespersons

The spokesperson’s role is to communicate directly with media through briefings and interviews and to interact with the public. Designate a primary and backup spokesperson during planning activities. The spokesperson may be the water system’s Public Information Officer (PIO), a manager assigned to communication, or someone within the communication network, such as a local public health department representative. The spokesperson is someone in authority who is honest, credible, competent, accessible, and sensitive to public concerns. Use the Spokesperson Assessment Tool.tool icon [DOC - 1 page]

The spokesperson must be ready to interpret scientific and technical information into clear language and must understand the water system’s operations. Professional training in media management, effective listening, and handling sensitive situations is helpful in preparing a spokesperson to be ready to meet the media and the public at any time.

Integrate Communication into Emergency Response and SOPs

SOPs must be clear and allow users to take actions based on the information they will have at the time. SOPs should establish clear chains of command and communication so that authorized personnel can make situation-specific decisions. SOPs may include the following:


Fill out Toolbox templates before an advisory and incorporate and regularly review and update them in your communication, ERP, and operations SOPs.

  • Purpose: Objective of the SOP (e.g., delineation of authority, roles, and procedures).
  • Scope: People involved, and the authority and responsibilities they have.
  • Communication Structure: Organizational chart that demonstrates levels of command and communication linkages.
  • Protocols: Procedures for action within the SOP’s purpose.
  • Training: Requirement(s) and schedule.
  • Exercising: Procedures and schedule.
  • Oversight/Update: Person(s) responsible for assuring compliance with and maintenance of SOP.

Customer Call Center

Call centers and customer service (CS) staff are on the front lines during an advisory. Call centers must have the resources to respond to customers above and beyond normal operations and hours. Information provided through the call center must be accurate, timely, and consistent.

The actions described below apply to local government call lines such as 411, community lines such as 211, or other agencies that may respond to an advisory.

Briefings: Meet with call center and CS staff before issuing the advisory and provide essential information on the scope, scale, and severity of the advisory.

Scripts: Provide scripts to call center and CS staff developed with essential information and frequently asked questions (FAQs).

Updates: Meet with call center and CS staff to check for adequate staffing and customer concerns. Add and revise information in scripts as needed.

Resources: Ensure enough phone lines and staff for the scope and scale of the advisory. Staff will need current information and referral contacts.

Debriefing: Include call center and CS staff in the advisory debriefing to identify communication activities and resources.
