The STEP project involves construction of 41m of a deep sewer tunnel, 43km of supply tunnels, which will be smaller in diameter to transport the sewage to the treatment plants, and an underground pumping station at Al Wathba with a pumping capacity of 30m³ per second. The tunnel will start at a depth of 27m underground and reach a depth of 100m towards Al Wathba Mapei UTT provided foaming-agents, slurries for TBM, admixtures for back-fill grouting and the product MAPECOAT W SP for the final coating. 2 EPB TBMs Herrenknecht (diameter 7 m) plus 3 EPB TBMs Herrenknecht (diameter 6.3m )m. The 5 TBM of Impregilo completed the 2 contracts T02 and T03 , total lenght 25 Km.
