Germany to provide Euro 120 million soft loan for Clean Ganga Mission

Germany has announced to provide soft loan of euro 120 million (Rs. 990 crore approximately) to India to strengthen sewage water treatment infrastructure in Uttarakhand in an effort to clean River Ganga under Clean Ganga Mission. German development agency GIZ also has prepared ‘Ganga Box’ aimed to target schools-going children and inform them about the river.

Key Facts

The proceeds from this soft loan will be used for project focusing on extension and replacement of sewerage system (around 360 kilometres) including complete house connection, construction of sewage treatment plants (STPs) of around 15 million litres per day (mld). The purpose of project is to reduce inflow of untreated waste water in River Ganga and, thus, to improve the water quality of the river. This project also includes construction of 13 sewage pumping stations.

Ganga book

Ganga book has been prepared on lines of ‘Danube Book’ when cleaning of European river was undertaken. This book will have information mythological, socio-cultural, economic importance about river and suggestions to avoid pollution, like not dumping plastic in water body. Its aim is to bring behavioural change of people towards Ganga River. Ganga book project has been piloted in government schools in Uttarakhand and it will be replicated in other states.

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.
