The water intake tower is the main structure within the key engineering project. The lower part of the water intake tower uses an enlarged foundation with a foundation elevation of 435.50m. The top elevation of the tower base is 450.00m. The tower base is a regular octagon with a diameter of 15.0m and a height of 14.5m. The tower body is constructed of C25W8F50 reinforced concrete, with a top elevation of 501.3m and a height of 65.8m. The diameter of the hollow circular core within the tower body is 9.0m. The diameter of the core is 12.6m from 450.00 to 457.0m, 12.0m from 457.00 to 472.00m, 11.4m from 472.00 to 488.00m, and 10.8m above 488.00m. The total height of the tower is 72.1m.
