[1] Water supplied by the BWA in Barbados is pumped from wells within natural coral aquifers.
The geology of Barbados is mostly composed of karst limestone which acts as a filter medium within the aquifers.
Due to high demand, a desalination plant was built to augment the existing groundwater.

Prior to the introduction of indoor plumbing to all of the houses on the island, it was a common practice for most areas in Barbados to have a communal-based standpipe.
