Noida will build two new Ranney wells along the Yamuna in sectors 132 and 135, adding a planned 34 million litres per day (MLD) to the city’s water supply capacity at an estimated cost of ₹45 crore, according to the Noida Authority. Each well will have a capacity of 17 MLD.
The projects are intended to strengthen Noida’s water supply during interruptions in Ganga water distribution caused by canal cleaning or technical problems. The authority plans to draw water through the new wells and supply it to residents after treatment, with the proposed water quality estimated at 300 to 400 total dissolved solids (TDS).
Noida requires more than 450 MLD of water each day, according to the report. At present, around 240 MLD of Ganga water is supplied from treatment plants at Pratap Vihar and Siddharth Vihar in Ghaziabad. The city also receives approximately 110 MLD from tubewells and about 100 MLD from existing Ranney wells.
R P Singh, general manager (water) of the Noida Authority, said the city currently has eight operational Ranney wells supplying around 100 MLD daily. Three additional Ranney wells are also expected to begin operations soon. Once those projects and the two proposed wells are operational, Ranney wells are expected to provide around 160 MLD to Noida’s water network.
Ranney wells are horizontal infiltration wells that draw groundwater or filtered riverbank water through collector pipes placed below the surface. Their planned expansion reflects Noida’s effort to diversify its supply sources rather than rely primarily on Ganga water, whose availability can be affected when the Ganga canal is shut for maintenance or faces technical disruptions.
The authority has also pointed to Faridabad, where around 32 Ranney wells are reportedly in operation and form an important part of the city’s water supply system. Noida is considering a similar expansion along the Yamuna to improve supply availability during periods when its primary source is interrupted.
The two new wells will be located in sectors 132 and 135 along the Yamuna. The authority’s stated next steps are to prepare and implement the projects, while the three other Ranney wells are expected to be commissioned soon. The report does not specify construction or commissioning dates for the two new wells.
