While there are many ideas that tackle the current problem of constructing toilets in rural households, our idea is more visionary in that it aims to tackle the problem of handling the potentially increasing sewage directed at current waste-water treatment plants.
It is safe to assume that the wastewater treatment plants constructed in rural areas are exempt from considerations of toxic and/or industrial wastes. Thus, the challenge becomes to address only the increasing amount of waste generated by people in the villages. Given our experience being Indian citizens, it is a well-known fact that the water from sewage treatments plants is directed towards water bodies. If it should happen that expansive seas or oceans are far away, wastes are released into local water bodies. These are the same water bodies used by people living in houses with inadequate facilities to bathe, wash, and drink from marking the starting point of water-borne diseases and other issues related to poor hygiene.Our idea is to use market-based approaches to improve the capacity of wastewater treatment plants and expand their services to as many villages as possible. Our key innovative solution to direct the excess slurry generated by them to community bio-digesters where they will be converted into biogas and manure. The biogas will be supplied to that very community for a monthly tariff, making the entire operation profitable for its investors, while the manure will be directed to farms. This would impact our farmlands and groundwater resources by reducing the dependency of farmers on chemical fertilizers, thereby decreasing groundwater pollution due to such toxic chemicals. Our idea has the potential to reduce the eutrophication load on local water bodies, creating opportunities for other start-ups and technology innovators to tackle the underlying water pollution issues.
- Involving lending organizations to help the government build wastewater plants
- Utilizing current water credit system to generate revenue to build community bio-digesters
