Potable water treatment facilities are an essential requirement for a Martian settlement. A number of the following processes may be required, depending on the source of the water. Some industrial processes will produce clean water than can be used in a potable water system. Waste water treatment facilities are very similar to water treatment facilities, but will treat more heavily contaminated water. In a closed loop system, the cleaned waste water is returned to the potable water treatment system for re-use.

Water treatment processes

Reverse osmosis

Sand filtration

Chlorination

Ozonation

Arctivated charcoal

PH balancing

Flocculation

Desalination

Organic solids removal

Expected contaminants
Water treatment plant

The first water treatment plants will be packaged units provided from Earth. These types of units are already produced on Earth for buildings and communities isolated from the larger centralized water treatment plants available for towns and cities.
