Water consumption was increasing, for example in Chicago the per capita water consumption was 33 gallons per day in 1856 to 144 gallons in 1882 (although this figure also includes industrial sources). This increased water consumption and the growing use of water closets overloaded the existing cesspool system and served to contaminate the ...
The history of water supply and sanitation is one of a logistical challenge to provide clean water and sanitation systems since the dawn of civilization. Where water resources, infrastructure or sanitation systems were insufficient, diseases spread and people fell sick or died prematurely. Astronaut Jack Lousma taking a shower in space, 1974
An example of a water distribution system: a pumping station, a water tower, water mains, fire hydrants, and service lines [1] [2].

The theory of ion exchange involves replacing undesirable or potentially harmful ions with more desirable or harmless ones. This is implemented in domestic water treatment system as water softeners.

The RBC process allows the wastewater to come in contact with a biological film in order to remove pollutants in the wastewater before discharge of the treated wastewater to the environment, usually a body of water (river, lake or ocean). A rotating biological contactor is a type of secondary (biological) treatment process.
