The size of the water diversion tunnel can be shorter than the dam’s 22.5 kilometers with a Four-meter diameter.

He mentioned within the dam and tunnel portion of the challenge, the consumption weir’s price is 30% cheaper, whereas 50% cheaper when taken along with the challenge’s different elements such because the water therapy plant.
