An emergency chlorination plan is required for each community water system. Each municipal water system shall have appropriate chlorination infrastructure and chorine available to obtain 0.5 mg/l free chlorine throughout its distribution system within 4 hours. A working chlorine meter shall also be available to measure chlorine concentrations. To ensure water systems are capable of emergency chlorination, the department may ask that an emergency chlorination test be conducted by the water supplier for a municipal water system. At a minimum, the emergency chlorination plan shall include: NR 810.26(8)(a)(a) Location and description of chlorine pumps, solution containers, chemical, and chlorine test meter. NR 810.26(8)(b)(b) Procedures for adding chlorine to the water system, flushing the water system to move chlorine to extremities, and testing chlorine levels. NR 810.26(8)(c)(c) Example calculations for determining dosage requirements. NR 810.26 HistoryHistory: CR 09-073: cr. Register November 2010 No. 659, eff. 12-1-10; correction in (6) made under s. 13.92 (4) (b) 7., Stats., Register November 2010 No. 659. subch. II of ch. NR 810Subchapter II — Surface Water Treatment and Groundwater Under the Direct Influence of Surface Water Treatment Operations NR 810.27NR 810.27 General requirements for all surface water and groundwater under the direct influence of surface water systems. NR 810.27(1)(1) This subchapter establishes criteria under which filtration is required as a treatment technique for public water systems supplied by a surface water source or a groundwater source under the direct influence of surface water. Direct influence shall be determined for individual sources by the department. The department determination of direct influence may be based on site-specific measurements of water quality characteristics such as those stated in s. NR 810.02 (25) or documentation of well construction characteristics and geology with field evaluation. These regulations also establish requirements for treatment techniques in lieu of maximum contaminant levels for Giardia lamblia, viruses, heterotrophic plate count bacteria, Legionella, Cryptosporidium and turbidity. Treatment technique requirements apply to every public water system which utilizes surface water or groundwater under the direct influence of surface water and the requirements consist of installing and properly operating water treatment processes which reliably achieve: NR 810.27(1)(a)(a) At least 99.9% or 3-log removal or inactivation of Giardia lamblia cysts between a point where the raw water is not subject to recontamination by surface water runoff and a point downstream before or at the first customer. NR 810.27(1)(b)(b) At least 99.99% or 4-log removal or inactivation of viruses between a point where the raw water is not subject to recontamination by surface water runoff and a point downstream before or at the first customer.
