Drinking Water Rules



Current Rulemakings

1. Emergency planning at public water systems: proposed permanent rule amendments

2. Very small public water systems requirements: proposed permanent rule adoption and           amendments to streamline and consolidate requirements


1. Emergency planning at public water systems: proposed permanent rule amendments
The Oregon Health Authority, Public Health Division (OHA) is proposing to permanently amend Oregon Administrative Rule 333-061-0064 related to emergency planning for public water systems. The amendments are necessary to improve and streamline emergency planning requirements and to be consistent with the American Water Infrastructure Act.

Specific amendments and proposed rule language are identified in the documents available below, which include:

Summary of Key Rule Changes
  • According to these proposed revisions, the emergency response plan rule would only apply to community and non-transient non-community water systems. Drinking Water Services still recommends that water suppliers responsible for transient and very small water systems maintain an emergency response plan for those water systems.

  • For community systems serving more than 3,300 people, the revised rule aligns with the federal American Water Infrastructure Act (AWIA) so that only one plan must be developed for water systems to meet the requirements of different emergency management requirements. Drinking Water Services is proposing the following in addition to the AWIA:

    • Identifying connections delivering water to vulnerable groups.
    • Developing response procedures for events involving high-risk contaminant sources or activities identified in a water system’s source water assessment.
    • Describing procedures for notifying customers, water users and local media.

  • A simplified emergency response plan will be required for community water systems serving 3,300 people or less and non-transient non-community water systems.

Previous Rulemaking

Permanent rule amendments requiring an examination to be certified as the operator of a small water system.

The Oregon Health Authority, Public Health Division (OHA) permanently amended Oregon Administrative Rule 333-061-0228 related to the training and certification of individuals as small water system operators. This change requires operators to pass an examination to earn this certification, beginning on August 1, 2022. The amendments were necessary to be consistent with federal guidelines and thereby preserve federal grant funding, because federal guidelines require an examination before operator certification is granted.
Small water system certification is required at community and non-transient non-community public water systems serving 150 service connections or less, and that use only groundwater sources or where finished water is purchased from another public water system.  Visit the Small Water System Operator page for more information.

Specific amendments and proposed rule language are identified in the documents available below, which include:




Oregon Revised Statue (ORS) Oregon Drinking Water Quality Act
Enacted in 1981, the statute (periodically amended) includes Oregon Revised Statute (ORS) 448.119 to 448.285; 454.235; and 454.255. The purpose of the above act is (in part) to:
  • Ensure that all Oregonians have safe drinking water;
  • Provide a simple and effective regulatory program for drinking water systems; and
  • Provide a means to improve inadequate drinking water systems.

Current Oregon Administrative Rules (OARs) for Drinking Water

ORS 448.131 authorizes Drinking Water Services (DWS) to adopt administrative rules to ensure safe drinking water. OAR Chapter 333 Division 061 is reserved for regulations regarding public water systems and was last amended on January 1, 2021.
