Here, Lothian Region Water & Drainage Dept
was installing new drainage deep underground close to where the
Edinburgh International Conference Centre now stands in Morrison
Kitted in boots, hard hat and overalls, I descended to the tunnel
and my camera bag was lowered down the shaft by crane.
The tunnels were being blasted, drilled
then dug out. They extended for 300 meters underground.
The work was being carried out 12 hours a day, 6 days a week and was
expected to continue until early 1992.
