What We Need to Build


Nutrient removal Reactor by Siemens

Disc filter

Disc filter technology used to ensure the smallest micro organisms are captured and destroyed

Micro tunneling

Micro-tunneling to safely install the Deep Gravity Sewer beneath Muharraq


The construction phase of the project has three main elements:

1. Sewage Treatment Plant

2. Deep Gravity Sewer

3. Network Connections

The sewage treatment plant is designed to treat up to 100,000 m of waste water every day. It will use proven technology, including pre-treatment, nutrient? removal, filtration to 10 microns and disinfection using both UV and Chlorine.

The sewage treatment site will also have an incineration plant to reduce the sludge generated to a small volume of ash.

To deliver the waste water to the treatment site, a Deep Gravity Sewer pipeline? is needed.? This will be constructed by tunneling at up to 15 meters below the ground.

The pipeline follows the main Al Ghous and Khalifa Al Kabeer Highways, before crossing to Hidd near Arad Fort. It then follows the Hidd Ring Road to a Lift Station on Dry Dock Highway.

After the Lift Station, the pipeline route is along Dry Dock Highway to the junction with Sheikh Khalifa bin Salman Causeway. The route then follows the Causeway to the site of the new treatment plant, which is located on an island of reclaimed land, linked to the Causeway by an access road.

To minimize any disruption to traffic, the pipeline will be constructed by ‘Micro-Tunneling’. With this technique, the only excavation at the surface is for a number of shafts. The tunnel machine is placed into the ground at the required depth at one shaft and slowly bores its way through the earth to the next shaft.? As the machine moves forward, the pipes are jointed in the shaft to form a pipeline, which is then pushed forward behind the tunneling machine.

The connections to the existing sewer network will only be made after the new pipeline has been fully tested.
