Is Mombasa Tap Water Safe To Drink?
No, it's not advisable to drink the tap water.
Tap water in Mombasa is treated by the local water utility, but it is not consistently safe to drink straight from the tap. Aging pipes, intermittent supply, and contamination during distribution or household storage can affect water quality.
Drink bottled water or boil tap water for at least one minute before drinking. Use a properly maintained filter for additional protection, especially for infants, older adults, and people with weakened immune systems.

Source of Water in Mombasa, Kenya
Mombasa’s tap water mainly comes from the Baricho Wellfield in Kilifi County, where groundwater is drawn near the Galana-Sabaki River and treated before being piped to the city. Additional supplies come from Mzima Springs in Taita-Taveta County through the Mzima pipeline.
The county also receives water from the Tiwi and Marere sources in Kwale County. These sources are treated and distributed by the Mombasa Water Supply and Sanitation Company through the city’s network.
Mombasa Drinking Fountains
Public drinking fountains in Mombasa should not be assumed safe unless they are clearly maintained and supplied by an approved treated-water system. Contamination can occur through damaged pipes, storage tanks, dirty outlets, or inadequate maintenance.
Use fountains that are clean, regularly serviced, and labeled as having potable water. When their safety is uncertain, choose sealed bottled water or water treated by boiling, filtration, or disinfection.
