Current through June 25, 2024
Water systems shall be classified in accordance with the
						criteria outlined below. Special systems which do not fall within these
						guidelines shall be considered as individual cases and be classified by the
						Bureau. All public water systems shall be under the direct supervision of a
						Bureau certified waterworks operator who is designated by the owner or
						responsible official of the system as the operator in responsible charge of the
						water system. In those situations, where a public water system contracts with a
						private operating company to operate the public water system, the responsible
						official of the public water system may authorize the private company to
						designate an operator employed by the company as the operator in responsible
						charge of the water system. In either case, the water system shall identify, by
						means of the Public Water Supply Annual Report submitted each year to the
						Bureau, the certified operator in responsible charge of the public water
						system.
