A point of entry water treatment system. Components mounted on a base frame are interconnected and provide a system and method for treating freshwater, including from a lake, river, well or cistern, to provide potable water. A pre-filter removes sediment and reduces turbidity, followed by chlorine disinfection of the water. Finally, the water passes through an activated carbon filter to remove remaining free disinfectant and by-products resulting from the application of the disinfectant. Controls are provided that prevent untreated water or raw disinfectant from being output by the system. The controls also dampen the cycling of the system major components to reduce wear and maintenance.
