numbers of municipal tube wells, 216 numbers of mini municipal tube wells,
and 2448 numbers of municipal hand pumps are satisfying 137 MLD water
demand of the city. The private hand pumps and tube wells are satisfying the
54 MLD water demand of the city, which is not in the records of JS and JN.
Table 20 details out the water works for Allahabad municipal area.
It has also been estimated that the intake of water from Yamuna River in 2003
was 80 MLD whereas the remaining 137 MLD water drawn from 157 deep
tube wells operated by the JS (Table 21). The quality of water is reported to be
of acceptable standard.

The raw water from River Yamuna is being tapped (80 MLD) at Karelibagh
raw water pumping station which is pumped to Khusro Bagh water works for
treatment before it is supplied to the consumers.
The existing condition of the treatment plant is poor. The clarriflocculation
unit of the plant, which is one of the main units of the WTP, is not functional.
The sedimentation tank is serving the purpose of the clarriflocculation unit.
Coagulant is being added in raw water in the raw water channel for the
coagulation and sedimentation of suspended solids in the sedimentation tanks.
Total capacity of settling tank is 177 MLD. Effluent from the sedimentation
tank passes from the filter beds of rapid gravity sand filters. Total filtration
capacity of the filter is about 135 MLD. The filtered water is chlorinated by
chlorine gas with the help of chlorine toners. The water after filtration and
chlorination is stored in the clear water storage tanks. Water from the clear
water storage tanks is pumped and served to the community and about 35% of
total water being supplied to the city is being fulfilled by this WTP.
