As night falls over the northern highlands of Lesotho in early July, winter's chill sets in. Yet the Polihali Transfer Tunnel construction site remains a hive of activity.
The 38-km tunnel will be excavated using two hard-rock shielded tunnel boring machines (TBM), operating simultaneously from Polihali and Katse.
Speaking at the ceremony, South Africa's High Commissioner to Lesotho Constance Seoposengwe said she believed the new machine would give further impetus to the already ongoing work on the project.
"The Lesotho Highlands Water Project is more than just a water project," she said. "Local jobs have been created, and new roads have been built in the Kingdom."
