In olden days canals were considered as the most reliable form of transportation for the people of Kochi. But then came urbanization and industrialization, which resulted in people turning to roads instead of water ways and all the canals across the city turned into a garbage pit which is now filled with non degradable waste, human waste and a lot more.
Thevara-Perandoor canal, a 10.58 km long canal is one of the arterial canals of Kochi city. This canal is not manmade, but now it is filled with manmade wastes and other garbage and became a breeding ground for mosquitoes. Dark water, disgusting smell and the only life that they produce is that of mosquitoes. Even at the time, when contagious diseases are spreading across the city, people close their eyes and throw all the waste into it.
It is the same with canals like, Kalvathy canal, Edapally canal and the rest. All of these canals have been encroached to the edge and at times a bit more. And people who lives besides these canals throw their garbage into these canal. Restaurants, household wastes and to make matters even worse, even the sewage ends up in these canals without being treated, filled with human excreta.
