The purpose of the following two questions, WS5 and WS6, is to determine whether the household drinking water is treated within the household and, if so, what type of treatment is used. This question is intended to gather information on water treatment at the household level and not water treatment at the municipal or vendor level. --- Circle the code corresponding to the response. The household may be using a method that you know does not make water safer to drink. Do not use your own judgement, just record the response. Record all items mentioned (for example, the household may be filtering the water and adding chlorine at the same time). Probe: "Anything else?" Circle 'X' for 'Other' and specify on the line provided what the household does to the water to make it safer to drink. Circle 'Z' if the respondent 'Doesn't know'. Definitions of various methods of water treatment are as follows: 'A' - Boil refers to boiling or heating water with fuel. 'B' - Add bleach/chlorine refers to using liquid chlorine bleach or bleaching powder to treat drinking water. SURVEY COORDINATORS: FREE CHLORINE MAY BE USED IN THE FORM OF LIQUID SODIUM HYPOCHLORITE, SOLID CALCIUM HYPOCHLORITE AND BLEACHING POWDER (CHLORIDE OF LIME) 'C' - Strain it through a cloth refers to pouring water through a cloth that acts as a filter for collecting particles from the water. 'D' - Use water filter involves water flowing through a filter made of ceramic, sand or a combination of materials to remove particles and at least some microbes from the water. SURVEY COORDINATORS: CERAMIC MAY INCLUDE CLAYS, DIATOMACEOUS EARTH, GLASS AND OTHER FINE PARTICLES. 'E' - Solar disinfection consists of exposing water, stored in buckets, containers or clear vessels, to sunlight. 'F' - Let it stand and settle refers to storing water undisturbed and without mixing long enough for larger particles to settle to the bottom by gravity. The settled water is carefully removed by decanting, ladling or other gentle methods that do not disturb the settled particles.
