Abu Dhabi takes big step towards sustainability

Management of wastewater is a critical component of Abu Dhabi’s strategy to achieve long-term sustainability. The Strategic Tunnel Enhancement Programme (STEP) is designed to manage stormwater flows and enable water recovery and reuse to meet projected increases in demand throughout Abu Dhabi.

Abu Dhabi Sewerage Services Company (ADSSC) needed global water infrastructure and geotechnical expertise coupled with local presence to help deliver the programme.


STEP involves one of the world’s biggest underground pumping stations, over 100m deep and 50m in diameter. Our specialists are managing its construction, including contractual, cost, health and safety and environmental aspects, while also providing high-level overview of the contractor’s design. A project of this scale requires very broad-ranging skills which we’re providing for ADSSC by connecting our global experts.


We've contributed to a world-leading sewerage solution by being able to identify potential technical issues early, provide rapid and timely responses for onsite queries and engender an ethos of collaborative working. The project’s excellent safety record, 6M man hours without a lost time incident, has helped earn our client a Gold Award from the Royal Society for the Prevention of Accidents, the first to be awarded to a public sector company in the Middle East.
