Overview of the STEP Programme
The Strategic Tunnel Enhancement Programme (STEP) is a 40-kilometer long wastewater tunnel in Abu Dhabi, UAE. The programme is in direct response to aggressive growth set forth in recent years. This growth plan was formalized in 2007 with the release of Plan Abu Dhabi 2030. Specifically the Plan states "The current infrastructure capacity will not meet the forecasted demand and the resulting development envisioned in the Urban Structure Framework Plan". STEP addresses these needs for the collection and transport of used water from all the expansion in currently developed areas and development of new areas identified in the Plan. It is also sized to accommodate the range of flows that could result from the development.
STEP will also be a critical part of the system which will generate over 15 m3/sec of grey water for irrigation.
