NMCG is an independent body of the Government of India, which has been constituted to take measures for prevention, control and abatement of environmental pollution in the Ganges and to ensure continuous adequate flow of water so as to rejuvenate the Ganges.
Meanwhile, UPJN is the state body in charge of executing the projects related to water and wastewater in the state of Uttar Pradesh. Founded in 1975, UPJN enforces and implements the mandate of NMCG to rejuvenate the Ganges as one of its activities with the aims of developing and regulating water supply and sewerage services in the whole state except the cantonment areas.
India with the world's second largest population is advancing rapidly. However, a large part of the population does not have access to drinking water and proper sanitation because the vast majority of wastewater is discharged without treatment into water resources, such as rivers, lakes and groundwater. The rejuvenation of the Ganges under the aegis of NMCG is one such platform where joint efforts are made by the central and state governments, urban local bodies and private sectors to create a synergy for the success of the 'Clean India' Initiative. The 14,000m3/day sewerage treatment plant in Salori Allahabad is one of the projects commissioned under this initiative and supported by the World Bank.

SBR is a variant of the activated sludge process, which operates on the fill and draw principle.
The SBR process eliminates the need for primary and secondary clarifiers. The unit processes of fill, react, settle, draw and idle occur sequentially on a cyclic basis. In the fill phase, screened and de-gritted wastewater flows into the basin. In the react phase, the basin is aerated. During the settle phase, aeration is stopped to allow solids to settle to the bottom of the basin. During the draw phase, treated wastewater is decanted. Sludge is wasted during the idle phase.
High quality treated water is discharged into the Ganges as per the latest norms of CPCB.
The treated water quality meets the customers' expectations.
The dewatering and sludge treatment equipment is used to remove 80% of the excess water in the process of sludge treatment.
