History of Sanitation

Meet the network evolution Actual Sanitation

The history of sanitation has its roots in antiquity, in which their development was motivated by religious cities and shopping centers or. As a notable example can point the sewage with which they had Rome, built on the 600 A.C. and called "Cloaca Maxima", pouring waste into the Tiber river city.

It is known that sanitation was created in response to a health problem such.

Industrialization led to the uncontrolled mass of the population around the production centers, creating an absolutely appalling sanitary conditions, which numerous epidemics have highlighted the connection between the health status of drinking water and disease development led.

Although many cities had, several centuries before, Duct Drainage, they were designed, exclusively, for stormwater drainage, to the point that in the England of the early nineteenth century was forbidden discharging wastewater to these ducts.

The first step in solving the problem was the construction of drains in buildings-which, until then, only possessed, a lo sumo, wells of black-and its connection to the drainage pipes, giving rise to the first sewer unit type, system, later, was adopted by most of the cities.

In 1842 Sir Edwin Chadwick produced a report on the sanitary conditions in Britain which established the need to collect wastewater in a specific sewer system, propose the use of ceramic pipes and sewage separation stormwater, advocando by separate systems with his famous statement: "The rain water from the river and the residual field." From 1847, the requirement to connect the buildings to the sewer was established.

Ultimately, It is from British initiative, middle of the last century, when modern sanitation foundation established, specifically in relation to the first aspect thereof: collection and transport of wastewater.

However, the construction of the first sewage systems showed that, though contributing to reduced number of inlets, improving, evidently, local conditions from the previous situation, a higher concentration of the contamination occurred, that, immediately, was a worsening of the state of rivers, creating unacceptable health and environmental conditions, so the idea that the wastewater discharge should not take those suggested, but should be used to fertilize the soil, whereby the first treatment system proposed and completed the earlier concept of sanitation, based on the collection and transportation of waste water, with your debugging.

From this point, the first purification systems are developed, initially led to the removal of solid matter and subsequently supplemented with soluble organic materials by the biological treatment, first trickling filters (1897) and, later, activated sludge (1914).

We can say that in the late sixties and has developed considerable scientific basis in regards to conventional biological treatments, de facto, has lasted until today.
