Varanasi is all set to become the first city with zero discharge of polluted water into river Ganga. By July this year, the sewage treatment capacity of Varanasi will exceed 400 million liters per day (MLD), checking the flow of sewer water in the river completely.

The government has hired a private concessionaire for cleaning Varanasi’s 84 ghats for three years at the cost of Rs 5 crore per year. Similarly, the Government will spend Rs 13 crore for cleaning 94 ghats in four cities of Uttar Pradesh—Kanpur, Prayagraj, Bithoor and Mathura-Vrindavan.

Under the Namami Gange program, for Varanasi, the upcoming sewage treatment plant (STP) at Rammana with a capacity of 50 MLD will treat the polluted water coming from Assi river, which is a major source of pollution in the Ganga. The current sewage generation in Varanasi is estimated at 300 MLD, which is expected to increase to 400 MLD in the year 2035. At present, the three operational STPs in the city have 102 MLD treatment capacity. However, with the upcoming 3 STPs, the total sewage treatment capacity will go up to 412 MLD, which is adequate to meet the demand until 2035.

Similarly, the Ministry of Ganga Rejuvenation under Nitin Gadkari has put a thrust on Ganga cleaning activities at the ongoing Kumbh in Prayagraj. The government sanctioned projects for the treatment of sewage water coming from 53 drains in Prayagraj for six months in view of the Kumbh. Further, Rs 113 crore was sanctioned for over 47,000 toilets at the Kumbh.

This is in addition to the ongoing sewage treatment facilities at Prayagraj and its adjoining areas. Officials said three new STPs at Naini, Jhusi and Phaphamau in Prayagraj would treat 72 MLD of sewer water before being discharged into the Ganga. The Namami Gange project consists of 261 projects, 194 of which deal with constructing STPs, rural sanitation and bioremediation largely spanning Uttar Pradesh, Uttarakhand, West Bengal, Bihar and Jharkhand, which are responsible for most of the pollution. Most of the 221 projects under the Namami Gange Mission worth Rs 25,563 crore are at advanced stages of completion.
