According to the managing director of Abu Dhabi Sewerage Services Company (ADSSC), Alan Thomson, the aforementioned project, plus the 42km-long link service tunnel, will both be finished by the first quarter of 2015.

The project, which comprises pumping stations to be done by the end of 2015, will be commissioned in phases, and it is estimated to be equipped by 2016. The whole project, called the Strategic Tunnel Enhancement Programme (STEP), will be amounting to 5.7 billion dirhams ($1.5 billionn).

Furthermore lessening the carbon footprint of Abu Dhabi’s sewerage procedure, the eco-friendly tunnel will also help save 4.2 billion dirhams ($1.1 billion), which can then be used on energy and preservation costs for the next 25 years.

The deep tunnel, which begins at 27m underground and arrives at a depth of 100 metres, is not estimated to oblige regular maintenance for the next 80 years. The new tunnel will also help substitute 34 pumping stations in the existing system that spend big amounts of energy with just one pumping station at Al Wathba treatment plant.

Additionally, the tunnel which will lengthen from Karama in Abu Dhabi to Al Wathba treatment plant, will triple the capacity of Abu Dhabi’s sewerage network too. The existing system deals with 400,000m3 of sewage a day, but the new tunnel can carry 1.7mn m3 of sewage, which is the estimated demand by 2030.
