  The most pragmatic first step in the all-but-inevitable 3rd-millennium
V\"olkerwanderung of humanity throughout the Solar System is the establishment
of a permanent human presence on the Moon. This research examines: 1. the
human, agricultural, and technical water needs of a 100-person, 500 m x 100 m x
6 m self-sustaining lunar colony; 2. choosing a strategic location for the
moonbase; 3. a heat drill model by which the needed lunar water ice could be
sublimated; and 4. the robust water treatment and recovery infrastructure and
water management personnel that would be needed for a self-sustaining moonbase.
