The reservoirs, located in Sectors 116 and 117 and built at a total
cost of around Rs 174 crore, will be used to store Ganga water. Laying
down pipelines linking these reservoirs with the Pratap Vihar water
treatment plant will be completed in a month.

Residents will soon be supplied more Ganga water
which will reduce the quality of hardness in potable water supplied to
the city. Authority officials said that work on the three reservoirs has
already been completed and simultaneously pipelines are being laid to
get Ganga water from the treatment plant. “In a little over a month,
work on laying the pipelines will be completed. The Authority will begin
trial operations in May,” said an official.

The reservoirs
have capacities in the range of 44,000 to 55,000 kilolitres each. As per
targets set by the Noida Authority, the net water demand in the city is
set to reach 215 million litres per day (MLD) by 2015.

However, with the commissioning of these three reservoirs, over 240 MLD
of Ganga water would be at the disposal of the Authority.

“Plans are afoot to supply purified Ganga water alone to residents
instead of mixing it with groundwater as has been the practice for many
years,” added the official. In order to beat the hardness of groundwater
in the city, the Noida Authority has been supplying potable water to residents by mixing groundwater with Ganga water.
