Is Tap Water Safe to Drink in Eswatini?
Tap water in Eswatini's main urban areas like Mbabane and Manzini is generally treated to reasonable standards, but rural areas and smaller towns face inconsistent quality, so caution is still warranted. Filtering or boiling is recommended outside major cities.
Water Source
Mbabane draws from the Mbabane and Polinjane rivers along with the Hawane Dam, while Manzini relies partly on the Lusushwane River. The Maguga Dam on the Komati River, part of a joint project with South Africa, supplies irrigation and some domestic water in the northern Hhohho region.
Contaminants & Concerns
Agricultural runoff from sugarcane plantations along the Komati and Usutu river valleys introduces fertilizer and pesticide residues into some surface water sources. Informal settlements around Manzini and Mbabane sometimes lack full sewage connections, raising the risk of bacterial contamination reaching shallow groundwater used by nearby communities.
Regional Variations
The Eswatini Water Services Corporation (EWSC) operates treatment plants in Mbabane, Manzini, and the Ezulwini valley that generally meet acceptable standards for urban customers, with relatively good infrastructure by regional standards. Rural areas served by the Rural Water Supply Board depend more on boreholes and gravity-fed schemes, which have inconsistent maintenance and testing.
Water Hardness
Surface water from the Komati and Usutu river systems is moderately hard, typically 90–130 mg/L, reflecting the granitic and gneissic geology of the Highveld..
Do Locals Drink Tap Water?
Urban residents in Mbabane and Manzini often drink treated tap water directly, though many households also keep bottled water for guests or infants. In rural areas, people frequently rely on borehole or river water, sometimes boiled before drinking.
