Is Tap Water Safe to Drink in Sierra Leone?

Freetown's supply comes from the Guma Valley Water Company, drawing from the Guma Dam and Orugu treatment works in the hills above the city, but treatment capacity falls far short of demand. Outside Freetown, most communities rely on hand-dug wells, boreholes, and streams, many of which are unprotected from contamination.

Widespread contamination with E. coli and other fecal coliforms results from inadequate sewage infrastructure, informal settlement runoff, and pipe network leaks that allow sewage infiltration. Cholera and typhoid outbreaks occur periodically, particularly during the rainy season when flooding overwhelms Freetown's drainage and sanitation systems.

Freetown has the country's only significant treatment infrastructure, yet supply reaches only a fraction of residents reliably, forcing many to rely on water vendors and unprotected sources; rural districts such as Kono and Kailahun have minimal treated water access at all.

Water hardness is generally low to moderate, with Guma Dam surface water typically measuring 30–80 mg/L, though groundwater from boreholes in laterite soils can be somewhat harder..

Sachet water (locally called 'pure water') is the most common drinking source in urban areas, though quality varies widely between producers, and boiling remains common in households without reliable access to sealed water.

• •Drink only bottled or sachet water from reputable sealed sources
• •Boil water for at least one minute before drinking or cooking if no bottled water is available
• •Avoid ice from informal vendors
• •Use water purification tablets when traveling outside Freetown

• •Verify sachet water packaging is intact and from a known producer
• •Avoid well water in informal settlements without boiling or filtering
