Some surface water might be less polluted and only filtration and disinfection are enough to obtain purified water.

Organic matter from the washing of dishes and clothes and from human activity in toilets, pollutes the water. This waste water collected in the sewerage needs to be treated before discharging it into the river beds or into the sea, and especially when this water is going to be reused for irrigation or other purposes. Otherwise this wastewater can transmit all kinds of diseases to people and animals that have contact with it.
