Borehole drilling for sewage disposal at Asuka Station, East Antarctica

A borehole for sewage disposal was drilled at Asuka Station (71°31′34″S, 24°08′17″E, 930m a. s. l.) in January 1987. The borehole, 400mm in diameter and 27.5m in depth, was drilled 50m distant from the main hut using a steam drilling system. The drilling speed was 4m/h between the snow surface and 2...

Description
Summary:A borehole for sewage disposal was drilled at Asuka Station (71°31′34″S, 24°08′17″E, 930m a. s. l.) in January 1987. The borehole, 400mm in diameter and 27.5m in depth, was drilled 50m distant from the main hut using a steam drilling system. The drilling speed was 4m/h between the snow surface and 20m depth. The total amount of kerosene used for melting snow and steam generation was 110/. Sewage stored in the tank was directed to the borehole through a heated pipe. The cumulative amount of sewage was 1077k/ for 5 years, and the bottom of the hole rose 14m.
