Sanitation
The health conditions of the people related to the disposal of sewage, human excreta and provision of clean drinking water is known as sanitation.

Poor sanitation and usage of contaminated drinking water leads to the occurrence of many diseases. Thus the sanitation system aims to provide a clean environment for us so that we can stay away from diseases.
The cause of diseases
In India, a substantial fraction of people defecate in the open on dry riverbeds, on railway tracks, nearfields and many a time directly in water. This human excreta is a health hazard as it is untreated. This pollutes the water by polluting both the surface water and groundwater. As the groundwater is the source of water in the wells, tubewells, springs and most of the rivers it serves as the most common route for various water-borne diseases such as cholera, typhoid, meningitis, polio, hepatitis and dysentery.
The importance of sanitation at public places
India is a country in which there are massive public gatherings. Also, there are numerous places in our country which are very busy such as airports, railway stations and bus depots where thousands of people gather daily. Hence in these places, a large number of waste is generated and must be disposed of properly as it may lead to several and epidemics.
Even though the government has laid down certain standards, they are not followed strictly. Hence, it is mandatory that all of us should contribute in maintaining sanitation at public places.
Certain practices that we should follow to maintain sanitation are as follows:
  • Always throw the garbage in the dustbins.
  • Avoid spitting in public places.
