Is Tap Water Safe to Drink in Ethiopia?

Addis Ababa draws from the Gefersa and Legedadi reservoirs in the surrounding highlands, along with the Dire Dam, all fed by highland streams. Rift Valley towns like Ziway and Awasa rely on groundwater and lakes that carry naturally elevated fluoride from volcanic geology.

Rift Valley groundwater and some lake sources contain fluoride levels far above WHO guidelines, contributing to widespread dental and skeletal fluorosis in parts of Oromia and the SNNPR region. In Addis Ababa, rapid urban growth has outpaced sewage infrastructure, allowing bacterial contamination into aging pipes, particularly in informal settlements.

Addis Ababa's water utility treats water from Gefersa and Legedadi to reasonable standards, but supply is intermittent in many neighborhoods, forcing reliance on stored water that can become recontaminated. Rift Valley towns face the added challenge of natural fluoride contamination that ordinary treatment does not remove, making alternative sources important in that region specifically.

Highland reservoir water supplying Addis Ababa is moderately soft to moderate, around 60–100 mg/L, while Rift Valley groundwater can be much harder and more mineralized, often exceeding 200 mg/L along with high fluoride..

Many Addis Ababa residents boil tap water or buy bottled water brands like Highland or Yes, especially for children. In Rift Valley towns, awareness of fluoride risk has grown, and some communities have shifted toward bottled water or fluoride-removal filters where available.

• •Drink bottled or filtered water throughout Ethiopia, including in Addis Ababa
• •Avoid tap water in Rift Valley towns due to fluoride risk, even if it looks and tastes normal
• •Use water purification tablets or a filter when trekking in rural highland areas
• •Avoid ice unless you know it was made from purified water

• •Avoid tap water in Rift Valley towns regardless of appearance or taste
• •Boil water in Addis Ababa if bottled water is unavailable
• •Use fluoride-specific filtration in high-risk regions rather than standard boiling
• •Be especially cautious giving tap water to children due to fluorosis risk
