Amman Service Reservoirs

ENKA completed the turn-key construction of eleven ground level water reservoirs with a total capacity of 160,800 m3, 3 water towers, 4 pump stations and 3 instrument houses.

In this project, very interesting construction method was undertaken, a 600 ton concrete covering water tower was constructed on the ground, with a specific form system, and later was raised by a heavy lifting method to 23 m and erected. This difficult process, which requires great care, was completed in 3 days.
