The USA branch installed 2 sets of water tanks and feeder boreholes on the campus. One is installed next to the old administrative building and services that building including the toilets for the old form 1 and form 2 building. The other is located near the old Swanston House and features 4 -2000 liter tanks.  It services the GCIOBA Building, Senior Staff Quarters and Junior Secondary School 1 environment. Both have the impact of providing a more reliable water supply to the campus.
