Noida: Experts from the Central Land Water Commission (CGC) will soon conduct hydrological surveys to ensure ways to increase groundwater levels throughout the city.
Authority officials Noida said the three-month survey would help identify the problem areas and ETCH solutions with estimated costs to be used to develop groundwater conservation plans in the coming months.
The city, which faces upward annual depletion up to 5-6 feet, currently has 11 raney wells where six operations are almost dry.
The other four are damaged while someone is contaminated and, therefore, does not operate.
Ranney Wells is a radial type used to extract water from aquifers with direct connections to surface water sources such as rivers or lakes.
“Ranney Wells is the main source of drinking water because they are found near the river.
In the case of Noida, it is Yamuna.
Water, which was previously found at 30-40 meters below the ground level, withdrawn with a 150 meter wide pipe which is placed horizontally together with These wells.
Of these six to seven years, six of these wells lying in almost dry conditions due to sustainable groundwater thinning, not only in the city but also in Yamuna.
This is a big task to make this functional Ranney Wells, “Rp.
Singh, Deputy General Manager (Department of Water and Sewer) from the Noida Authority, to the Toi.
He added that the groundwater level in Noida has dropped from 30-40 meters in 2002 to almost 110-115 meters in recent years.
“For Ranney’s well recovery and groundwater conservation, we have involved experts from the Ministry of Water Resources., Who, in turn, has hired experts from CGC.
These experts will begin the hydrological survey in February.
Once we will know how much Lots of ground water drained and in which areas, we will take steps on the government’s orders on how to limit their extraction.
This step will be based on the advice of experts, whether it limits borewell or unwanted withdrawal to make wetlands, “Singh said.
The authority will develop a plan based on the study of experts, to implement the steps of groundwater conservation, which will be the second part of the 15-month project
