What is CaribDA?
The Caribbean Desalination Association (CaribDA) is a non‐profit organization that The
Caribbean Desalination Association (CaribDA) is a non profit organization that
represents its members from the Greater Caribbean desalination and water reuse communities, utilities, industries, academia and government as well as individuals interested in water supply improvement in the region specifically by means of desalination or water reuse. CaribDA will encourage communication and liaisons with other water treatment associations in the region and throughout the world (i e IDA ALADYR CWWA Global
associations in the region and throughout the world (i.e. IDA, ALADYR, CWWA, Global Water Partnership, etc.).
The Association was formed to share experiences, information, operational data, technical standards and other resources; work together to improve the quality and quantity of d d

potable water; and lower the costs of production through application of desalination technology and water reuse in the Caribbean.
CaribDA is a platform for desalination and water reuse owners, designers and operators and others involved or having an interest in desalination and water reuse.

“The Caribbean may not have been desal’s birthplace, but it has been its most prolific proving ground. Most islands maintain strong historic and cultural ties to Europe South America or the US and the region’ss predominance of small to Europe, South America or the US, and the region
predominance of small
projects and the extensive use of BOO/BOT contracts makes it ideally suited for pilot and beta testing of new technologies. The region continues to play a big role in demonstrating that seawater desal can be a reliable municipal water supply.” WDR Volume 48 , Issue 25 , June 25, 2012

Caribbean Desalination History
From Dr Jim Birkett’s keynote address CaribDA 2012 conference in Aruba Caribbean Desalination History
The Water & Power Authority of Aruba (WEB) just celebrated it’s 80th year in desal and their Curacao counterpart (Aqualectra) it’s 75th two years ago.
The first ME plant in Aruba started operation in 1932

• Supplies potable water to the small fishing/whaling community of Paget Farms in Bequia.
• A containerized 5 m3/hr (35,000 gpd) RO desalination plant was installed by Caribbean Water Treatment Ltd. (St. John’s, Antigua).
• A 75.9 kW photovoltaic solar system was installed nearby at the J.F. Mitchell Airport in November, 2011 by Grenada Solar Power Ltd. • The solar power system was sized to offset the Th

GE Wind powered SWRO plant at Tarpum Bay

Not direct drive but to the grid and is still being assessed as a project.
Commission date for the wind power commission is early 2013.
The project’s first phase, construction of a Meteorological Tower, is designed to collect data on wind speed, air pressure, direction and temperature for 12 months. The feasibility study will determine the viability of wind power at Tarpum Bay.
Schneider Power together with WINSO Company Ltd. has formed Eleuthera Wind Power Ltd to supply renewable energy to the Tarpum Bay SWRO plant. They have a MOU for a 20 year power supply agreement with WSC which is estimated to be B$0.20/kWhr compared to the B$0 37 paid on average presently
B$0.37 paid on average presently.
Eleuthera Wind Power’s $2 million wind farm, when completed, will supply only the 400,000 IGPD (GE) SWRO plant at Tarpum Bay which supplies Water & Sewerage Corporation customers with potable water.

The project seeks to lower the cost of energy in Dominica and to substantially increase electricity production from renewable energy renewable in the Eastern Caribbean,.”
•
This project is likely to lead to the development of the first geothermal power plant of 20 MW which will produce for the local market, then a second, which could produce up to 120 MW of electricity for the export.
•
This project will enable Dominica and neighboring islands to have a clean, sustainable energy, “they may indeed respond to the demand for electricity using a renewable energy source rather than primarily fossil. The project will represent an important source of income for Dominica. It will reduce its heavy expenses in foreign currency‐induced
Dominica. It will reduce its heavy expenses in foreign currency
induced imports of diesel and imports of diesel and
significantly reduce the energy bill supported by its people. If it proves successful, it could become a model for other small island developing states have geothermal potential. “
