For the IEEE SIGHT funded project "BeShuddho: A Tank Based Water Purification System", all the materials, designs and code blocks are organized in this repository.
In such an unrestrainedly industrializing and densely populated country like Bangladesh, clean drinking water is a scarcity. Due to the negligence of the relevant authorities in providing a safe water supply Bangladeshi families usually resort to purifying water by themselves. A 2019 report by Transparency International Bangladesh shows that 35% of people complained of foul smells and poor water quality. The report further showed that 91% of people boil water before drinking, which is tedious and burns gas equivalent to 332 crore BDT annually. In Doniya, a union inside Dhaka, Bangladesh the water supplied by the WASA (Water Supply and Sewerage Authority) has so poor quality that most residents cannot use the water for any drinking or cooking purposes. For drinking water, they have to rely on the nearest water pumping station of WASA or any deep well water pump. Even that does not solve the exact problem, they use a water purifier or boil the water before drinking to ensure water safety. Therefore, through this project, we propose an affordable, automated water purification system with impurity-detecting sensors for the low-income 3 households of Bangladesh. The project "BeShuddho" is a system that will purify the WASA-supplied water when it enters the rooftop water tanks for the whole house (3+ families). At first, the system detects incoming water flow using sensors that trigger the purification system. The water must pass through a UV barrel that is compatible with the incoming water flow. And a microcontroller-controlled system controls UV-barrel filteration.
