The issue of cross connection and backflow prevention came up recently when a Kansas funeral home was required to make some plumbing adjustments in their embalming/preparation room after being inspected by a representative from the Kansas Department of Health and Environment (KDHE), Division of Environmental Field Services. While the KDHE does not have specific regulations or statutes which pertain to protection of the public water supply from backflow/backsiphonage from a funeral home, Kansas does have broad regulations and statutes concerning the protection of public water supply, including:
KAR 28-15-18. See section (f).
KSA 65-163a
KSA 65-171g
Additional information can be found under the KDHE's Bureau of Water and Engineering and Permits Unit where you will find information on the KDHE's minimum design standards entitled "Policies, General Considerations, and Design Requirements for Public Water Supply Systems in Kansas," 2008 edition.
