A Delhi Jal Board official said Wazirabad and
Chandrawal water treatment plants had to be closed down at
around 2.00 pm due to very "high ammonia content" in the
Yamuna raw water.
The officials attributed the increase of ammonia
content to the discharge of industrial and domestic waste in
the Yamuna by Haryana.
The ammonia content had increased to 1.4 PPM (parts
per million) against the normal quantity of 0.6 PPM forcing
the DJB to close down the plants.
The official said the plants may be re-started only
when there is a substantial reduction in the ammonia level.
Following closure of the plants, water supply has been
affected in several areas in North, Central, South and West
Delhi as well as in NDMC areas.
The DJB has requested the residents to conserve water
as supply of water through tanker in these areas may not be
possible due to non-availability of treated water at filling
The official said release of industrial and domestic
in Panipat and other cities of Haryana is being taken up with
the neighbouring state and Central Pollution Control Board
The DJB had to shut down these two plants in December
last year also following high ammonia content in Yamuna water.
New Delhi: Several areas across the city
on Monday faced water shortage after two major water treatment
plants in the city were closed down after finding high
quantity of ammonia in the Yamuna.
