Is Tap Water Safe to Drink in Côte d'Ivoire?

Abidjan draws mainly from the Continental Terminal aquifer via boreholes, supplemented by surface intakes on the Comoé and Bandama rivers for some upcountry towns. Lake Kossou, formed by the Kossou Dam on the Bandama, supplies water and hydropower to the central region around Bouaké.

Bacterial contamination from pit latrines leaching into shallow wells is common in peri-urban Abidjan neighborhoods like Abobo and Yopougon. Seasonal flooding between June and October can overwhelm SODECI's distribution network, allowing sewage intrusion into cracked pipes, while agricultural runoff from cocoa and rubber plantations introduces pesticide residues near rural intakes.

Abidjan's piped network, operated by SODECI, is the most reliable in the country and meets WHO bacteriological standards at the treatment plant, but intermittent supply means household storage tanks are a common re-contamination point. Rural and northern areas near Korhogo depend heavily on hand-pump boreholes, many installed by NGOs, with inconsistent maintenance.

Water from the Continental Terminal aquifer is generally soft, around 40–70 mg/L, while surface water from the Bandama can run slightly harder at 80–110 mg/L depending on season..

Many urban residents drink sachet water sold cheaply on the street, though quality control on these sachets varies widely. Wealthier households in Abidjan increasingly install home filtration or buy bottled water like Awa or Aquavie.

• •Drink bottled or filtered water outside central Abidjan and Yamoussoukro
• •Avoid ice in drinks from street vendors
• •Use a portable filter or purification tablets if traveling to Korhogo or Man
• •Check that household storage tanks are cleaned regularly if on a piped connection

• •Boil water for at least one minute if no filtration is available
• •Store treated water in clean, covered containers
• •Avoid raw produce washed in untreated tap water
