Kumbh mela is observed every 12 years while Ardh Kunbh mela comes every
6 years. The estimates suggest that around 7-10 crore people throng on the city
during the mela so as to take a holy bath at the holy Sangam.
The mela lasts 40-45 days during winters (January 13 till the first week of
March). Analysis suggests that the per day floating population during the
festival would be approximately 15 lakh to be spread over and the Kumbh
ground area of 7.47 km 2 or 747 ha (Master Plan 2021). Considering a
population density as 225 persons per ha, total population would be about 1.68
lakh in a single day. It would therefore be reasonable to consider and provide
water facility for a population of 2.5 lakh @ 20 lpcd. Total water demand at
this rate would be of order 50,00,000 litres per day i.e. 5 MLD.
7.4 Key Issues Though at city level all the indicators reveal that service levels are well above
the desired norms, but the key issues with regards water supply system are:
Fall in water level of Yamuna during summers. This has adversely affected
the intakes of two wells of the Karelibagh raw water pumping station;
Rapid unauthorized expansion of the city is responsible for stretching the
work of the JS beyond limits;
High elevation of some localities makes water pressure difficult;
There are frequent power failures for prolonged periods causing severe
damage to the system operation as well as the operational schedule;
For supply of water to consumers, the intended schedule by the authority is
an intermittent supply spread over a daily period of 10 hours in three shifts,
6.00 am to 10.00 am, 12.00 noon to 2.00 pm, and 6.00 pm to 10.00 pm.
This schedule with adequate levels of supply can hardly be met due to
various operational constraints. Residents at lower elevations receive water
for longer durations as against those at higher locations;
Large quantity of water is lost through the system due to leakages in
pipeline and appurtenances as well as due to unaccounted for water
consumption. There are huge losses to the extent of 40% in the system;
A number of components in the system have inadequate capacity. This
includes – raw water pumping mains, clear water reservoirs in
Khushroobagh Water Works, zonal overhead tanks and pipelines at various
