EPA Standards & Recommendations
Monday, May 4, 2020

During the Stay at Home Order, many Ohio businesses, manufacturing facilities, churches and community buildings have been vacant or only partially occupied.  As buildings within your distribution system that have had little to no water usage re-open, it is important that they flush water that has been stagnant in cold- and hot-water distribution lines and fixtures. It is also critical that buildings drain, flush and disinfect devices that store water like drinking fountains, hot water heaters, dental and medical equipment, and manufacturing devices that spray or mist water.

If your non-community public water system is about to re-open, please contact your Ohio EPA District Office inspector to discuss flushing, monitoring and compliance requirements prior to opening.

Low water usage in buildings can lead to water quality deterioration that may be associated with public health risks including bacterial growth and unsafe levels of metals. 

The Ohio Department of Health and the Ohio Environmental Protection Agency have developed recommended procedures that are posted at A letter for building occupants, owners and tenants is also available at
