Municipal water filtration systems have been around for centuries. Even people several centuries back realized the need for safe, clean public water and started demanding it from their leaders. This demand was based mostly on an Enlightenment period concept that folks had certain natural rights, for example a right to drink and wash in clean water. Philosophers of the age spent hours pondering on this subject, and the general consensus was that the folks were right in their expectations. As a consequence, different water purification techniques were introduced. In 1804, the 1st city-wide water filtration system began operation in Scotland, and the idea spread from there. In the modern era, we have all started to expect civil water filtration as one of our unalienable rights.

Community water filtration facilities spread in appreciation due to augmenting technologies and the greater awareness that drinking unhealthy water might end up in epidemics and a public health crisis. Chlorine was first introduced into drinking water during a cholera epidemic and proved to be a useful purifying agent. About 98% of all drinking water treatment facilities now use chlorine to disinfect their water which translates into the incontrovertible fact that over 200 million Americans now receive chlorinated drinking water from their taps. Health statistics have shown over the years that water filtration and disinfecting systems have led on to a much fitter population in areas where it is practiced. Sadly, there are still areas on the globe without municipal water filtration systems where people still get ill and die of polluted water.

The system even in America , however , isn’t perfect. Waterways continue to amass every kind of contaminant known to man. Even though ecological problems came into focus in the 1960s and ’70s, and massive efforts were made to prevent factory waste products from getting dropped into our water resources, and although water filtration technology has vastly improved, the water these plants are attempting to clean continues to be dirtier and dirtier. Most likely this phenomenon is just the result s of the world being more populated than it was at any other time in the past. The challenge now is to either get serious about controlling the quantity of junk that continues to tip into our waterways or to invent still other techniques of municipal water filtration which will control much more massive amounts of contaminants in the future.
