Query: Water Care: Water Surface Cleaning Bot and Water Body Surveillance
  System   Whenever a person hears about pollution, more often than not, the first
thought that comes to their mind is air pollution. One of the most
under-mentioned and under-discussed pollution globally is that caused by the
non-biodegradable waste in our water bodies. In the case of India, there is a
lot of plastic waste on the surface of rivers and lakes. The Ganga river is one
of the 10 rivers which account for 90 percent of the plastic that ends up in
the sea and there are major cases of local nalaas and lakes being contaminated
due to this waste. This limits the source of clean water which leads to major
depletion in water sources. From 2001 to 2012, in the city of Hyderabad, 3245
hectares of lakes dissipated. The water recedes by nine feet a year on average
in southern New Delhi. Thus, cleaning of these local water bodies and rivers is
of utmost importance. Our aim is to develop a water surface cleaning bot that
is deployed across the shore. The bot will detect garbage patches on its way
and collect the garbage thus making the water bodies clean. This solution
employs a surveillance mechanism in order to alert the authorities in case
anyone is found polluting the water bodies. A more sustainable system by using
solar energy to power the system has been developed. Computer vision algorithms
are used for detecting trash on the surface of the water. This trash is
collected by the bot and is disposed of at a designated location. In addition
to cleaning the water bodies, preventive measures have been also implemented
with the help of a virtual fencing algorithm that alerts the authorities if
anyone tries to pollute the water premises. A web application and a mobile app
is deployed to keep a check on the movement of the bot and shore surveillance
respectively. This complete solution involves both preventive and curative
measures that are required for water care.
