Douglas, NFPA 850 specifically addresses wastewater treatment plants. Each process location and function is classified separately and the appropriate protection is specified, ranging from no requirements to hydrants and protable to automatic fire suppression systems. I don't know enough about the process you are describing to see how it fits into the protection requirements of the standard, but may fit into "Breakpoint Chlorination Tanks and Chlorine Contact Tanks - Application of chlorine in aqueous solution to wastewater" which requires hydrants for manual suppression (see Table 5.2, Row 17). Incidentally, by this standard, which may or may not be adopted through the building or fire code, the plant is supposed to have a fire risk evaluation and fire prevention program (see 10.3 and 10.4).
