The purpose of the first two questions of this module is to assess the type of household water used for drinking as well as for other purposes, such as cooking and washing hands. Definitions of the various sources of water are as follows (codes refer to those used in WS1 and WS2): '11' - Piped into dwelling, also called a house connection, is defined as water service connected by pipe with in-house plumbing to one or more taps, for example, in the kitchen and/or bathroom. '12' - Piped water to yard/plot, also called a yard connection, is defined as a piped water connection to a tap placed in the yard or plot outside the house. '13' - A public tap or standpipe is a water point from which the public may collect their water. A standpipe may also be known as a public fountain or public tap. Public standpipes can have one or more taps and are typically made of brickwork, masonry or concrete. '21' - A tube-well or borehole is a deep hole that has been driven, bored or drilled with the purpose of reaching groundwater supplies. Boreholes/tube-wells are constructed with casing, or pipes, which prevent the small-diameter hole from caving in and provide protection from infiltration of run-off water. Water is delivered from a tube-well or borehole through a pump that may be powered by humans, animals, wind, electricity, diesel fuel or solar energy. '31' - A protected dug well is a dug well that is protected from run-off water through a well lining or casing that is raised above ground level and a platform that diverts spilled water away from the well. Additionally, a protected dug well is covered so that bird droppings and animals cannot fall down the hole. '32' - An unprotected dug well is a dug well for which one or both of the following are true: (1) the well is not protected from run-off water; (2) the well is not protected from bird droppings and animals. If at least one of these conditions is true, the well is unprotected. '41' - A protected spring is a spring that is free from run-off and from bird droppings and animals. A spring is typically protected by a 'spring box' that is constructed of brick, masonry or concrete and is built around the spring so that water flows directly out of the box into a pipe without being exposed to outside pollution. '42' - An unprotected spring is a spring that is subject to run-off or bird droppings or animals. Unprotected springs typically do not have a 'spring box' (described above). '51' - Rainwater collection refers to rain that is collected or harvested from surfaces by roof or ground catchment and stored in a container, tank or cistern until used. '61' - A tanker-truck water source transports and sells water by means of a tanker truck. '71' - Cart with small tank/drum is used by a water provider who transports water into a community and then sells the water. Types of transports may include donkey cart, motorized vehicle or other means. '81' - Surface water is water located above ground and includes rivers, dams, lakes, ponds, streams, canals and irrigation channels from which water is taken directly. '91' - Bottled water is purchased water sold in bottles. Note that the code refers only to bottled water that is commercially available. Sometimes household members may store water from other sources in bottles - this should not be coded as bottled water. --- Circle the code for the most usual source. If several sources are mentioned, probe to determine the most usual source. If the source varies by season, record the source for the season of the interview. Note that the next question is only asked if the response to this question is 'Bottled water'. You should skip WS2 if the response to WS1 is other than 'Bottled water'. If the response is 'Piped into dwelling' or 'Piped into yard/plot', circle '11' or '12', respectively, and skip to WS5. Otherwise, skip to WS3.
