Is Tap Water Safe to Drink in Guyana?

Guyana Water Incorporated (GWI) supplies Georgetown and coastal areas primarily from groundwater wells and some surface sources, while much of the low-lying coastal plain sits below sea level, complicating drainage and treatment. Interior and hinterland communities, including many Indigenous villages, rely on rainwater, rivers, or creeks with little to no treatment.

Georgetown's tap water is frequently discolored (brown or yellow) due to high natural iron content and inconsistent treatment, and while iron itself is mostly an aesthetic issue, it signals broader treatment gaps that also allow bacterial contamination. Coastal areas below sea level face added risk from drainage and flooding affecting water infrastructure.

No part of Guyana, including Georgetown, is considered to have tap water safe for direct drinking by travelers. Interior regions accessible mainly by river or small aircraft, including areas near Kaieteur Falls and the Rupununi savannah, rely on untreated natural water sources.

Coastal groundwater tends to be soft but iron-rich, generally under 70 mg/L hardness, though iron content is the more noticeable issue..

Many Guyanese do not drink tap water directly, especially in Georgetown, where discoloration is common; boiling, filtering, or bottled water is widely used instead.

• •Drink only bottled or filtered water throughout Guyana, including in Georgetown
• •Expect discolored tap water in Georgetown — this reflects high iron content and treatment gaps, not just cosmetic issues
• •Bring a portable filter or purification method for interior and Rupununi travel

• •Drink only bottled, boiled, or filtered water throughout the country
• •Avoid tap water in interior and hinterland communities, which rely on untreated natural sources
