The drinking water coverage rate in Cambodia varies significantly by region. In the capital city of Phnom Penh, the coverage rate, which was approximately 25% in 1993, has exceeded 90%. On the other hand, rural areas have much lower coverage rates, with some regions reporting only around 38% as of 2015.

The Cambodian government has set a goal to achieve 100% water supply coverage in urban areas by 2025.
