The question tests understanding that disinfecting a new water main is a sequence of steps designed to clean, disinfect, flush, and verify safety before the line serves customers. Pre-flushing removes loose sediment and reduces turbidity so the disinfectant can work effectively on the pipe interior. Final flushing occurs after disinfection to clear out residual disinfectant and any loosened debris, ensuring the water entering the distribution system is clean and safe. Sampling and analysis provide evidence that the disinfection was successful by checking disinfectant residuals and looking for indicators of contamination, confirming the line meets safety standards before it is put into service. When you look at these steps together, each one is a distinct part of the overall four-step process, so including all of them makes sense.
