Is Sierra Leone Tap Water Safe To Drink?
No, it's not advisable to drink the tap water.
Tap water in Sierra Leone, within the Diego Martin Regional Corporation of Trinidad and Tobago, is generally treated by the Water and Sewerage Authority (WASA) and is considered safe to drink when supplied through the public network. Trinidad and Tobago’s public water supply is required to meet national drinking water standards.
Water from household storage tanks, private wells, or poorly maintained plumbing may not be safe without filtration or boiling. Boil the water before drinking if there is a local boil-water notice, supply interruption, discoloration, or unusual taste or odor.

Tap water in Sierra Leone, Diego Martin Regional Corporation, is supplied by the Water and Sewerage Authority of Trinidad and Tobago (WASA). The local supply is primarily drawn from surface water sources in the Northern Range, including the Diego Martin watershed.

Sierra Leone Drinking Fountains
Public drinking fountains in Trinidad and Tobago are generally safe when connected to the regulated public water supply, properly maintained, and clearly marked as drinking water. Water quality can still vary with plumbing condition, storage tanks, maintenance, and temporary service interruptions.
Avoid fountains that are dirty, damaged, stagnant, or lack a potable-water label. If the source or maintenance is uncertain, use sealed bottled water or boil the water before drinking.
