Should you boil the tap water in Dominica?

Do you need bottled water or a filter in Dominica?
Many visitors to Dominica stick to bottled water to be safe, and it's widely available — just check the seal is intact. A reusable bottle with a built-in filter is a lower-cost, lower-waste alternative.

Water treatment & pipe infrastructure in Dominica
