Non-Community Water Systems

Non-Community Water Systems (NCWSs) make up over two-thirds of all public water supply systems in the U.S. and in 2013 accounted for over 68,000 violations of the Safe Drinking Water Act, especially in the area of monitoring and reporting.

Best Practices

During 2012 and 2013, EPA convened a workgroup of state and EPA representatives to address the issues faced by NCWSs and the state programs responsible for regulating them. The workgroup developed a listing of “Best Practices and Resources for Building the Capacity of Non-Community Water Systems”, which is posted on the “States Only” section of the ASDWA web site (Login Required).


EPA has also launched a series of quarterly webinars to share information among the states regarding successful approaches and useful tools and information for addressing NCWS challenges. Video recordings of these webinars are found below, along with separate audio files (for downloading and using as a podcast) and copies of the slide presentations.

Getting Non-Community Water Systems Ready for the Revised Total Coliform Rule

August 19, 2014
This webinar includes the following presentations: Wisconsin’s plan to support non-community system compliance with the RTCR; RTCR implementation in New Hampshire; Utah’s “institutional grouping” approach for outreach to NCWSs (Forest Service facilities, versus churches, versus restaurants, etc.), as well as the state’s program of providing critical information to seasonal systems to make sure they properly understand and comply with start-up and other requirements; and an introduction to outreach materials being developed by EPA to assist states in preparing small water systems for their responsibilities under the RTCR.

(Please Note: We experienced technical difficulties during this webinar, and were not able to prepare a video recording. However, the audio file can be downloaded below, and you can download the slides and print them out or view them on your screen while listening to the audio portion of the webcast.)

CapCert Connections

ASDWA’s CapCert Connections is for state drinking water program operator certification and capacity development coordinators. Our goal is to share timely, informative articles designed to help make your efforts easier to accomplish; give you insights into what your peers are working on; and keep you up to date with meetings, workshops, and other plan-ahead events. We hope that this informationwill encourage greater collaboration between the Capacity Development and Operator Certification programs and enhance the ability of both programs to support drinking water systems across the United States.
