Chlorine is used to kill harmful pathogens in the treated sewage before discharge to a receiving watercourse. This is similar to its use in swimming pools. Similar treatment can be provided by using bromine, ozone or ultraviolet light.
An advantage of swimming is that it is a great way to stay in shape. However, the pools may often be cold and little clothing will have to be worn.
