How can sustainable reuse systems be developed to produce pure water from ablution water?

The challenge we face is developing a sustainable system to recycle and purify ablution water, which is used for religious washing practices, into clean, potable water. In many regions, especially in areas with water scarcity, the reuse of ablution water presents an opportunity to conserve this vital resource. However, the process of converting used ablution water into safe drinking water involves overcoming significant technical, health, and social hurdles. The system must effectively remove contaminants and ensure the water meets safety standards for drinking, all while being energy-efficient, cost-effective, and culturally acceptable. This problem statement focuses on finding innovative and feasible solutions to treat and repurpose ablution water, contributing to water conservation and addressing the pressing need for accessible clean water in areas with limited water resources.
How to develop Pest and Disease Management system: Managing pests and diseases in crops is a really big deal, especially in places where lots of people depend on farming to make a living. When pests or diseases damage crops, it can be bad news for farmers because they might not have as much to sell, and that can affect how much money they make. Also, if there’s a lot of pests, farmers might use more chemical pesticides to try to get rid of them. But those chemicals can be harmful to the environment and to people’s health. So, the challenge is to find ways to keep crops healthy and fight off pests and diseases without relying too much on these chemicals. This means looking for methods that are safer for the environment and for people, like using natural pest controls or different ways of farming that help prevent diseases. Doing this can help make sure that farming stays a good way for people to earn a living, and it’s also better for the planet and everyone’s health.
