Barbados Water

The natural spring water found in Barbados is among the purest in the world.

The state-run Barbados Water Authority Limited (BWA) is the exclusive supplier of potable water on the island.

Most of the water supplied by the BWA is pumped from wells within natural coral aquifers. The result is a water source of a naturally high quality.

Despite this, to comply with World Health Organisation (WHO) guidelines, Barbados treats its potable water with chlorine.

Ground water has always provided the largest source of Barbados’ supply, providing nearly 90%, according to one BWA survey. Of this, around half was drawn from just two wells, both of which were operating at near full capacity.

There are some 120 privately-owned wells, most of which provide water for irrigation purposes – agriculture being the country’s largest single water user, accounting for 23.5% of 1996 BWA figures for total consumption. The domestic sector comes a close second, at nearly 22%.

With declining rainfall in the 1990s and increasing consumption, Barbados turned to coastal desalination to supplement its water supply. The BWA had a $37.5 million desalination plant built at Spring Garden, St. Michael.

Claimed as the largest of its kind in the Caribbean, the Barbados plant began operating in February 2000, and supplies potable water to about 44,000 people – about one-sixth of the island’s population.

Barbados is classified by the UN Commission on Water as a “water scarce” country, making it particularly vulnerable to the effects of cyclic droughts. Against this background, the BWA is spearheading an integrated programme to better manage local water resources.

The desalination plant was a key plank in the programme. Current efforts are underway to reduce the amount of water lost by leaks in the distribution system due to deteriorating underground infrastructure.
