Explanation:

Government launched an integrated Ganga conservation mission called ‘Namami Gange’ to arrest the pollution of Ganga River and revive the river.
The Union Cabinet approved the action plan proposed by Centre to spend Rs 20,000 Crores till 2019-2020 on cleaning the river, increasing the budget by four-fold and with 100% central share – a central sector scheme.
Recognizing the multi-sectoral, multi-dimensional and multi-stakeholder nature of the Ganga Rejuvenation challenge, efforts have been made to improve the inter-ministerial, and centre-state coordination with increased involvement in preparation of action plan and increased monitoring at central and state levels.
The implementation of the program has been divided into entry-level activities (for immediate visible impact), medium term activities (to be implemented within 5 years of time frame), and, long-term activities (to be implemented within 10 years).
Entry-level activities includes river surface cleaning to address the floating solid wastes; rural sanitation to arrest the pollution (solid & liquid) entering through rural sewage drains and construction of toilets; renovation, modernization, & construction of crematoria that prevents the disposal of un-burnt/ partially burnt bodies in the river; repair, modernization & construction of ghats to improvise the human-river connect.
Medium-term activities will focus on arresting the municipal and industrial pollution entering into the river.
Under the long-term, providing adequate flow to the river is envisioned through determination of e-flow, increased water-use efficiency, and improved efficiency of surface irrigation.
