STEP Sewer Project

STEP Sewer Project

The STEP Link Sewer Contracts LS01 and LS02 transfer wastewater a distance of 40km through a network of micro-tunnels, with diameters ranging from 200mm to 2800mm, from Saatiyat Island to an area in Al Raha beach. The very deep micro-tunnelling works involved the construction of over 300 shafts at depths of up to 35m.
