Prior the introduction of the sewage systems, the number of individuals suffering from diseases such as hepatitis, typhoid or paratyphoid fever was considerably larger. Sewers hinder the dissemination of infections and keep our bodies sound. Without them or without pertinent disposal, we are susceptible to numerous maladies. What is more, the other living species are negatively influenced, too. On one hand, the aquatic plants face oxygen scarcity. On the other hand, fish get poisoned and very often perish.
In spite of the fact that the biggest part of the society is aware of the above-mentioned facts, we still find it arduous to tackle the sewage water pollution issues. There are people who are oblivious to the nature and its problems and continue throwing away the fluids they have already used wherever they can. There are also places where the supervision is not so strict and this results in disposal which is not appropriate.
Sewage water is the liquid which is already used by us at our homes, by the industries or the agricultural producers. Normally, it is expected to go into pipes. Their function is to lead it to channels which, on their part, transport it to the plants. The so- called plants are the facilities, which have the necessary equipment, where it is treated so as the big variety of noxious chemicals and organisms to be eliminated. Nonetheless, there are areas in which the responsible bodies fail to exercise the treatment procedure appropriately and expose their populations to hazards.
Prime Causes for sewage water pollution
The main reasons for this problem are related to the fact that enormous quantities of waste are refused directly into aquatic basins without being treated. When the fouled liquid is not processed prior discharge, it hosts pathogens which start contaminating. From then on, millions of organisms and chemicals appear in the rivers or the lakes. The phosphates which are a major content in the washing powders promote the algae development. These organisms need a lot of oxygen and greatly reduce the amounts available for the rest of the species.
Sometimes not our carelessness about our well-being but other factors trigger the problem. When there are torrential rains, many sewers brim over and become a direct threat for the man. The dirty liquid is on the surface and we can come into contact with it easily. If this is done, an infectious disease spread may burst out in a matter of days.
Provided that all authorised individuals monitor the sewage treatment activities, the humanity will solve this problem once and for all. These processes are more than enough because if correctly executed, they will eliminate all dangerous substances. That is so because they help extract all greases, oils or sands. The bio waste is attacked with microbes and after additional processing, it is good for irrigation of fields, lawns and even agricultural lands.
The wetlands are another major unit in the battle against the sewage problems. They are the perfect stage because there the treatment process may happen naturally. No man-made devices or techniques are used and this is not only better, but more feasible. Thanks to the bacteria in these places, the harmful chemicals are thinned.
This process is of vital importance not only for our well-being, but for our survival. The plants and animals will also take advantage of it. We now know more than ever before. We now can do more than ever before because we have the knowledge and resources to solve most of our problems. Therefore, we should not neglect the things which are within our power and may be improved. Through proper treatment, we could ensure wholesome life for the entire ecosystem.
