River Ganga drying up in summers due to groundwater depletion: Study

According to recent study conducted by IIT-Kharagpur, River Ganga has witnessed unprecedented low levels of water in several lower reaches in last few summer seasons. The study was carried out under IIT-KGP Science and Heritage Initiative (SANDHI) Initiative, which focuses on river systems and its relationship with settlement system. It had used combination of satellite images of groundwater levels of Ganga, numerical simulations and chemical analyses to draw the conclusion.

Highlights of Study

Drying of Ganga River in recent years during summer seasons is possibly related to groundwater depletion in Gangetic aquifers. The decline of groundwater inflow (base flow) is also impacting health of river. Present day base flow to Ganga from adjoining aquifers may be third or more of total river water volume in pre-monsoon months. The base flow might have dipped by 50% from beginning of irrigation-pumping phase in 1970s. In forthcoming summers, for next 30 years, groundwater contribution to river Ganga will continue decreasing. This trend can lead to disastrous effect on riverine ecology and lead to food scarcity for 115 million people in Ganga basin.

Significance of Study: It is of interest to hydrology, global change community and policymakers. It can help general public understand wider implications of groundwater depletion.  It also brings out scientific reasons for the decreased flows of the river Ganga, especially in the lower reaches. The findings will be extremely helpful in providing quantitative data for future planning of water resources projects in Ganga basin.

IIT Kharagpur to set up Re-Water Research Center

Indian Instituted of Technology (IIT)-Kharagpur has decided to set up Re-Water Research Center to replenish and rejuvenate water resources. It will be seed-funded by two alumni members – Aneesh Reddy & Aditya Choubey and named after them as Aditya Choubey Center for Re-Water Research.

Re-Water Research Center

The purpose of this centre will be to tackle challenge of resolving two burning issues faced by urban India – sewage disposal and access to clean potable water. It will network with government bodies to take up technology developed by it and process and meet the water challenge faced by various cities.

IIT-Kharagpur will set up an on-campus plant which will convert 1.35 million litre of sewage water from the hostels to 1.2 million litre of potable water on daily basis. The project aims to attract potential entrepreneurs and government agencies to take up sewage treatment atlarge scale and with business model for banks to gain confidence in funding such businesses. The pilot plant is expected to be ready by March 2019.
