Classes of Water Systems

Classes of Water Systems. 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. 1. Class E. Water systems that purchase water only and do not provide additional treatment. This classification shall also apply to waterworks operators whose only job responsibility is the operation and maintenance of the distribution system(s). The certified operator in responsible charge or his/her designee shall be available twenty-four (24) hours a day to address system needs and problems as they occur. 2. Class D. Water systems with no treatment other than chlorination and/or fluoridation or direct chemical feed such as polyphosphate. The certified operator in responsible charge or his/her designee shall be available twenty-four (24) hours per day to address system needs and problems as they occur. 3. Class C. Water systems with aeration, pH adjustment, corrosion control or closed pressure filtration treatment facilities including zeolite softening or iron removal. The certified operator in responsible charge or his/her designee shall be available twenty-four (24) hours per day to address system needs and problems as they occur. 4. Class B. Water systems with two (2) or more Class C treatment facilities of different types, with iron or manganese removal facilities breaking pressure or requiring flocculation and/or sedimentation, a system utilizing membrane filtration, or ion exchange treatment. The certified operator in responsible charge or his/her designee shall be available twenty-four (24) hours per day to address system needs and problems as they occur. 5. Class A. Systems with surface water treatment, groundwater under the direct influence of surface water, lime softening, or coagulation and filtration for the removal of constituents other than iron or manganese. A certified class A operator shall be onsite whenever the treatment plant for a Class A public water system treating surface water is in operation. The certified operator in responsible charge shall be available twenty-four (24) hours per day to address system needs and problems as they occur.
