I am little confused with your Question.......first you need to correlate with the Typhoid Fever and Raw water ! Then question comes why it needs disinfection of the raw water ?
Why you do not want to disinfect with Chlorine, what causing problem by chlorine...........you have already got any answers...........I do not want to go further discussion on it.
