Description

TRDISTILL indicates whether the household treats drinking water by distillation. Distillation uses a heat source to vaporize water, separating pure water from contaminants with a higher boiling point and killing bacteria, and then channels the steam through tubes to condense into purified water. Unfortunately, distillation is not practical for areas with water scarcity, since typically only one gallon of distilled water remains for every five gallons of water treated.

The information in TRDISTILL is taken from the household record and applies to regular household residents, not temporary visitors. Researchers may wish to exclude visitors using the RESIDENT variable (with visitors coded "2") when women, children, or births are the unit of analysis, and using the HHRESIDENT variable when household members are the unit of analysis.
