Improving Abu Dhabi’s waste water system

The Abu Hamour water drainage tunnel provides a major improvement in the capacity of Abu Dhabi’s waste water system.

The project includes a new deep gravity sewer tunnel which takes the main sewer flows from Abu Dhabi to a new treatment works outside the city, and a series of link sewers connecting into the deep tunnel.

The new deep gravity sewer tunnel is 45km in length. It varies in diameter from 5 to 6-8 metres along its length.

The tunnel was constructed with seven earth pressure balance (EPB)  tunnel boring machines (TBMs) which were launched and operated from seven deep shafts.
