The facility's water supply must be obtained from a public water system or, in its absence, from a supply approved by the Department of Agriculture and Natural Resources. Each private water supply must have a water sample bacteriologically tested at least monthly. The volume of water must be sufficient for the needs of the facility, including firefighting requirements. The hot water system must be capable of supplying the work and resident areas with water at the required temperatures. Maximum hot water temperatures at plumbing fixtures used by residents may not exceed one hundred twenty-five degrees Fahrenheit or fifty-two degrees centigrade. The minimum temperature of hot water for resident use shall be at least one hundred degrees Fahrenheit or thirty-eight degrees centigrade. Monthly monitoring of water temperatures is required and documentation must be maintained under facility policy.
Each water supply system in a facility must maintain one part per million free residual chlorine at remote point-of-use fixtures in the facility or the facility may use another bacteriological control method that has been demonstrated to be equivalent in control of Legionella. Increasing 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 is acceptable. The facility shall document water temperatures to verify the hot water temperature is being maintained within the acceptable range. If hot water temperatures are outside the acceptable range, chlorine testing must be done daily using photocell and light source DPD (N, N, Diethyl-p-phenylenediamine) test kits, and the test results logged. If testing demonstrates that consistent chlorine levels are maintained, monthly testing may be completed.
