Indicator NameAccess to water (access to an improved water source)
Short definitionAccess to an improved water source is currently defined as the percentage of the population that can obtain at least 20 liters per person per day from an “improved” source that is within one kilometer of the user’s dwelling. Improved water sources include household connection, public standpipe, borehole, protected well or spring, and rainwater collection, but do not include water provided through vendors, tanker trucks, unprotected wells, unprotected springs, and bottled water.
Long definitionAccess to an improved water source is currently defined as the percentage of the population that can obtain at least 20 liters per person per day from an “improved” source that is within one kilometer of the user’s dwelling. Improved water sources include household connection, public standpipe, borehole, protected well or spring, and rainwater collection, but do not include water provided through vendors, tanker trucks, unprotected wells, unprotected springs, and bottled water. Unsafe water and lack of basic sanitation is the direct cause of many water-related diseases in developing countries. This indicator monitors access to improved water sources based on the assumption that improved sources are likely to provide safer water and relates to the seventh MDG to ensure environmental sustainability.
