Scope of works
Kuwait is one of the few countries in the world aiming to recycle 100% of the
wastewater produced by its population and local industry.
The Umm Al Hayman Wastewater Treatment mega project is a $1.6 billion publicprivate investment providing complete recycling for up to 700,000 cubic metres
of wastewater a day and 456km of waste collection and final effluent distribution
pipework.
A joint venture between JGL and Bahraini marine contractor, Al Hassanain was formed
in 2020 to construct a 6.2km long, 2.4 / 2.2m diameter, Emergency Sea Outfall (ESO)
with three tunnels using state of the art pipe jacking methodology.
These are the longest and largest tunnels in the history of Kuwait. The 2km, 2.2m
diameter tunnel constructed under the coral sea bed of the Arabian Gulf is the longest
sea outfall in the Middle East achieved by pipe jacking.
The 4 day TBM recovery was extraordinary and is a massive triumph itself. A second,
2.4m diameter, 800m long, was installed on a vertical S Curve to pass beneath and over
existing utilities removing the need for diversions and deeper shafts. A third, 2.4m
diameter, 800m long, downhill tunnel formed the final tunnelled connection and the
remaining works were carried out by conventional, open cut techniques.
