During the recent Union Budget announcement, India’s Finance Minister Nirmala Sitharaman strengthened the commitment towards making India ‘Open Defecation Free’ and wanted to ensure 100 percent disposal of all liquid waste. A significant portion of the Rs.12,300 crores allocated to Swachh Bharat Mission this year will be used to roll out initiatives that will aid in the disposal and treatment of wastewater.
According to a report by IndiaSpend, 61,754 million liters per day (MLD) sewage is generated in urban areas while the country has the capacity to treat only 22,963 MLD. This means that approximately 70 percent of the wastewater generated remains untreated. Given the current water scenario in India, this becomes a critical factor to mitigate the water scarcity. In water-efficient cities, such as Frankfurt, water is recycled eight times before it reaches the ocean.
Technology is expected to drive India’s shift towards water efficiency and improved wastewater treatment considering the country’s ongoing water crisis, academicians, startups, and corporates have stepped in and shared their innovative solutions to alleviate the stress on the resource. The government is also working closely with countries, such as Israel to leverage their knowledge and innovation in these areas.
1. Internet of Things (IoT) in Wastewater Processes
Internet of Things has a growing influence on the water industry and is being increasingly used in wastewater processes. IoT sensors are used to collect data on water quality, temperature changes, pressure fluctuations, water, and chemical leakage. Sensors act as a communication device that sends data for analyzing the inputs, which then can be used to improve the process efficiency. The information can be shared with engineers, technicians and other management officials to give them actionable insights they might not otherwise have access to.
