S.D. Admin. R. 44:73:02:12.01
A facility shall maintain, for each water supply system in the facility, one part per million free residual chlorine at remote point-of-use fixtures, or another equivalent bacteriological control method for the control of Legionella. A facility may increase the water temperature range from one hundred twenty-two degrees to one hundred twenty-five degrees Fahrenheit, or fifty degrees to fifty-two degrees centigrade, for the control of Legionella. The facility shall document water temperatures to verify the hot water temperature is being maintained within the acceptable range for the control of Legionella. If hot water temperatures are outside the acceptable range, the facility must conduct chlorine testing using photocell and light source N, N, Diethyl-p-phenylenediamine test kits and log the test results. If testing demonstrates that consistent chlorine levels are maintained, the facility may conduct monthly chlorine testing.
