Section R309-530-4 - General(1) Alternative Methods. In addition to conventional surface water treatment, coagulation, sedimentation, and filtration as outlined in Rule R309-525, several alternative filtration methods may be suitable for treating surface water. They are direct filtration, slow sand filtration, membrane filtration, and diatomaceous earth filtration.
(2) Incorporation of Other Rules. The following requirements are incorporated into Sections R309-530-5 through R309-530-9 for alternative surface water treatment methods.
(a) Plant Siting, Section R309-525-6.(b) Pre-design Submittal, Subsection R309-515-5(2).(c) Plant Reliability, Section R309-525-7.(d) Color Coding and Pipe Marking, Section R309-525-8.(e) Chemical Addition, Section R309-525-11.(f) Miscellaneous Plant Facilities, Section R309-525-17, including Subsection R309-525-17(1), Laboratory.(g) Operation and Maintenance Manuals, Section R309-525-19.(h) Safety, Section R309-525-21.(i) Disposal of Treatment Plant Waste, Section R309-525-23.(j) Disinfection, Rule R309-520.(3) Source Water Quality Data. (a) A water supplier proposing to use alternative filtration to treat surface water or groundwater under the direct influence of surface water shall obtain sufficient source water quality data to: (i) determine the feasibility of alternative filtration treatment;(ii) identify substances that may affect the alternative filtration process and finished water quality; (iii) estimate productivity of the alternative filtration process; and(iv) determine if seasonal variation is substantial enough to affect design.(b) Source water quality data required by Subsection R309-530-4(3) shall be collected no more than two years prior to the date that plans and specifications for a treatment facility are submitted to the division.(c) The source water quality data for alternative filtration shall include at least: (i) one round of sampling for the contaminants required for initial analysis by Subsection R309-515-4(5); and(ii) four quarters of sampling collected over a period of 12 months for: (D) total organic carbon;(E) total suspended solids;(G) any additional parameter needed to design the treatment facility as determined by consultation with the division.(d) No later than the date that plans and specifications for an alternative filtration facility are submitted to the division, a water supplier shall also submit: (i) a summary of source water quality data used to design the facility; and(ii) a description of how the source water quality data address items (i) through (iv) of Subsection R309-530-4(3)(a).Utah Admin.
