why water for drinking is filtered and then treated with chlorine?

Answer 1

To keep out airbourne microorganisms that could decide to inhabit your drinking water and reproduce. Personally, I think there are better ways of taking care of this, but that's the reason why.

Answer 2

Filtration removes particulate matter.

Purification of drinking water containing pathogenic (disease-causing) organisms requires disinfection treatment. Disinfection of drinking water destroys pathogenic bacteria, nuisance bacteria, viruses and other microorganisms, to produce a drinking water considered by public health officials to be essentially pathogen free. Chlorination is the most commonly used method for drinking water disinfection. In addition, chlorine will oxidize iron and manganese so they can be filtered out and also oxidize hydrogen sulfide to reduce nuisance odors.
