Drainage and Irrigation system design and Execution for ICAD
....................................................................................................................................................


     ICAD is an industrial city located near to Musaffah Sea Port and in a close vicinity of
     Abu Dhabi International Airport and composed of:
     ICAD 1(covers an area of 14 sq km),ICAD2 (11 sq km)and ICAD3 (12 sq km).

     The scope of work consisted of Drainage system and irrigation mainline and control
    system  Design and execution.
     The subsurface drainage system consisted of Perforated HDPE pipes that cover all
     landscaped areas and carefully designed and coordinated to be compatible with the
     proposed road grades.The flexible 150 mm diameter HDPE pipes was installed in a 1.2 m
     depth trenches with gravel and geotextile and linked to the nearest manhole in the
     main drainage system.
     The irrigation mainline was of HDPE material with the biggest diameter of 800 mm,
     handling and welding the pipe was a great challenge; laid along a 2 wire path cables
     the irrigation mainline was connected at every sub main to a flow sensor where all
     the system could be control from one centralized satellite controller.
