Abu Dhabi is tripling its sewerage network

One of the region’s biggest wastewater engineering feats in Abu Dhabi is nearing completion and inspiring other projects in neighbouring Dubai and further afield in Saudi Arabia.
The Abu Dhabi Sewerage Services Company (ADSSC) is reaching the final stages of its Strategic Tunnel Enhancement Programme (STEP).
Costing $1.9 billion and started in 2008, the project includes a 41 km-long sewer tunnel and also 43 km of smaller diameter new link sewers.
Tripling Abu Dhabi’s sewerage network, the system will provide for an average wastewater flow of 800,000 m3/day, with an ultimate capacity of 1.7 million m3/day by 2030.
Regardless of the distribution, ADSSC will still hold responsibility for the collection and treatment of the wastewater.
