- Improved drinking-water sources are those that protect the water source from outside contamination such as fecal matter.
- Examples of improved drinking-water sources include: piped water into dwellings, public taps, tubewells, protected dug wells and springs, rainwater collection, and bottled water.
- Examples of water sources that are not considered to be “improved” include: unprotected dug wells, unprotected springs, vendor-provided water, tanker trucks, surface water, or bottled water if the secondary source used by households for cooking or personal hygiene is not an improved drinking-water source.
