Safe household water storage is a critical component of a Household Water Treatment and Safe Storage (HWTS) system being promoted by the World Health Organization (WHO) worldwide in areas that do not have piped drinking water. In these areas it is not uncommon for drinking water to be stored in a pot, jar, crock or other container in the home. Even if this drinking water was of acceptable microbiological quality initially, it can become contaminated from dirty hands and utensils, such as dirty dippers and cups. Drinking water containers with "narrow dispensers are key" to keeping water from being contaminated while being stored in the home.〔 〕 All types of 'safe household water storage must be used with water from known clean sources or with water having received prior efficacious treatment. ==Examples of containers== *Solar Cookers International (SCI) has incorporated the Safe Household Water Storage container in their water pasteurization programs in Kenya. They are part of a ''safe water package'' that consists of a CooKit solar cooker, a black pot, a Water Pasteurization Indicator (WAPI), and a Safe Household Water Storage container.〔 〕 The containers are handmade out of clay by local artisans. Their design incorporates a small opening at the top to help prevent children from dipping cups and possibly dirty hands into the drinking water. There is a spigot at the bottom. "Unfortunately, the spigot is almost as expensive as the container itself." In total each cost about 450 KSh (Kenya Shillings) or about US$6.00. The unglazed clay container helps to keep the water naturally somewhat cool in dry climates because a very small amount of the water is absorbed by the container and then evaporates. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Safe household water storage」の詳細全文を読む スポンサード リンク
