Noida Authority will build two new Ranney wells along the Yamuna in sectors 132 and 135 to strengthen the city’s water supply and provide an alternative source when Ganga water deliveries are disrupted. Each well will have a capacity of 17 million litres per day (MLD), adding 34 MLD to the city’s supply at an estimated cost of around Rs 45 crore.
The proposed wells are intended to supply water with total dissolved solids (TDS) of between 300 and 400, according to a report by Navbharat Times – Noida. The projects are planned as a support system for periods when Ganga water supply is interrupted because of cleaning work in the Ganga canal or technical problems affecting the network.
Noida currently requires more than 450 MLD of water every day. Around 240 MLD is supplied as Ganga water from treatment plants in Pratap Vihar and Siddharth Vihar in Ghaziabad. The city also receives about 110 MLD from tubewells and approximately 100 MLD from existing Ranney wells, which draw water from underground sources near riverbanks.
R P Singh, general manager of the Noida Authority’s water department, said the city currently has eight Ranney wells supplying around 100 MLD daily. Three additional Ranney wells are also expected to become operational soon. Once those wells and the two proposed facilities are in service, Ranney wells are expected to provide approximately 160 MLD to Noida, based on the figures cited in the report.
The planned additions are part of a wider move by the Authority to increase the number of Ranney wells in the city. The supply arrangement is intended to reduce the impact of interruptions in Ganga water, which can create shortages across Noida when the canal is being cleaned or when technical faults affect delivery from the Ghaziabad plants.
The Authority is also looking at the experience of neighbouring Faridabad, where around 32 Ranney wells are reportedly in operation and play an important role in the city’s water supply. Noida’s plan follows a similar model by expanding riverbank-based groundwater collection points rather than depending primarily on a single external source.
The proposed projects will add only part of the city’s daily requirement, but they will increase the capacity available during supply disruptions. The next steps are the construction of the two wells in sectors 132 and 135 and the commissioning of three other Ranney wells that officials said would begin operations soon.
