RAS question
Bisalpur Dam supplies drinking water to which major cities?
Correct answer: (C) Jaipur and Ajmer.
Bisalpur Dam on the Banas river in Tonk district supplies drinking water to Jaipur and Ajmer.
Explanation
Bisalpur Dam is the correct link for Jaipur and Ajmer because it is located on the Banas river in Tonk district and is described by Rajasthan Tourism as a major water source for the state. The official Tonk page calls it the lifeline of Jaipur and says it supplies water to around half the areas under the Jaipur Municipal Corporation, as well as to Ajmer district. Bisalpur is the primary drinking-water source for Jaipur through a 130 km pipeline and for Ajmer. The question therefore tests the city-supply role of a Rajasthan water project, not merely the dam's location.
Why the other options are wrong
- (A) Kota and Bundi do not fit because Kota's drinking-water linkage is with the Chambal, while Bisalpur is tied to Jaipur and Ajmer.
- (B) Udaipur and Chittorgarh are not the intended pair because Udaipur has its own lake-based supply context, not Bisalpur as its main source.
- (D) Jodhpur and Bikaner are wrong because Jodhpur's supply is associated with the IGNP pipeline, whereas Bisalpur is linked to Jaipur and Ajmer.
Concept
This tests Rajasthan geography through water-resource mapping: dam, river, district and dependent urban centres. RAS often repeats such links because they connect physical geography with public-service infrastructure, especially when a single project supplies major cities across district boundaries.
