Which of the following intake structure types suitability is true in case of a water supply scheme?
DSSSB JE - 2023,
Answer: D
The statement that submersible intake structures are normally used for lake-based water supply is the true one, as the key shows. A submerged intake sits below the water surface in the lake and draws water from there, so it works at every level of the lake. The other statements do not describe the usual practice: an intake tower is placed upstream of a dam (in the reservoir), not downstream, an underground chamber in the river bed is not the usual river intake, and a siphonic intake at the middle of the canal is not the way a canal supply is augmented.
