question:  What do the workers of WIlliamson Town do that causes them to lose water?
context: Portions of the turbine also volitized; idling at eight thousand RPM, it became unstable. The shaft tried to tie itself into a knot, and the blades, damaged and undamaged were spit through the casing. When he was broke, which was usually, he used his tractor to haul uranium ore and metallic sodium from the mines at Potter's dike to Williamson Town, where the rockets landed. By the light of this, he reinspected the steam system, and found about three gallons of water frozen in the condenser. The condenser, like all condensers, was a device to convert steam into water, so that it could be reused in the boiler. This boiling lowered the temperature, and the condenser demonstrated its efficiency by quickly freezing the water in the tank. If there was any water in the boiler, it would operate the engine that drove the generator. Then, if the pump wasn't blocked by ice, it would return the water to the boiler. Carefully he poured a cup of his drinking water into a pipe that led to the boiler, and resealed the pipe. The water that he had poured into the boiler quickly turned into steam, and the steam turned the generator briefly. They flickered as the boiler pressure began to fail, but the steam had melted some of the ice in the condenser, and the water pump began to function. This was to allow the air-conditioning system to function properly, and to prevent air loss in case of the highly improbable meteor damage. For example, because of an order of his stating that there would be no alcoholic beverages within the survey building, the entire survey was assured of a constant supply of home-made, but passably good liquor. It was used mostly, from sun-up to sun-down, to supplement the nuclear power plant. Three of the nine banks of mirrors would not respond to the electric controls, and one bank moved so jerkily that it could not be focused, and it threatened to tear several of the mirrors loose.
