On the island of Antigua, water is fundamental to the island's livelihood; the supply of this commodity, however, is not plentiful. Some water is available from natural sources; additional quantities are collected in cisterns. In 1987 a two train multi-effect distillation (MED) plant of 1.5 million gallons per day per train was commissioned. The first two sources sources have been affected by a pernicious drought and the latter by poor plant availability caused by corrosion and scaling problems. The island's economy is dependant on a continuous supply of potable water. Enserve, St. Maarten, N.V. developed a seawater reverse osmosis (SWRO) using DuPont's B-10 TWIN permeators to meet this need. This paper describes this new SWRO Plant and the sale of water contract. Difficulties in developing a water protocol within the Caribbean basin, performance of the 3 Train Antigua plant, testing, and future expansions are covered.
