The water crisis in megacities like Dhaka intensifies as we don’t realize how much water we use or how much we waste.  The primary purpose of our work is to reduce water wastage so that we can conserve water resources. In our paper, we tried to develop an integrated system, which will help people track and predict their water usage habits to suggest more efficient behaviours which will be easy to implement as well so that it can be popularised in megacities. Moreover, the system includes an option to reuse greywater by recycling it to reduce unnecessary water usage and prevent wastage. As a result, the proposed system will help us to improve our water usage behaviours and conserve our limited resources. 

Bangladesh is currently undergoing some massive economic changes, and the river bodies are being affected by pollution. Unethical practices are not accounted and the rise in economic growth translates to more industries, which is good for the economy but bad for the water bodies.In the current system, in order to tackle such issues, people resort to many types of water purification measures. With about 63.37% of the total population living in rural areas and at a poverty rate of 24.3%, expensive purification means, like reverse osmosis, is not an option for them. We developed a method to carry out flocculation with Naturally produced poly-glutamic acid with Moringa olifera seeds, which are abundant in nature.

The major emphasis of this study was to develop rapid, portable and highly-effective water purification device via capacitive deionization for on-spot water remediation with minimal energy consumption. The single-pass filtration experiments conducted at 1.2 V through the gravitational force demonstrated that the electrode fabricated from PET carbon aerogels and mixed plastic carbon aerogels is superiorly efficient by eliminating approximately 100% and 93.53% of both NaCl and As (5+) contaminants ions across a wide range of feedstock concentrations (50-1000 ppm) respectively, where the reverse osmosis system was proven relatively ineffective. This interdisciplinary study opens numerous possibilities for generating potable and affordable water when the access to electrical power is inadequate with protecting the ecosystem from the consequences of thermoplastic debris problem.
