2 Perception of the Caribbean

3 What is CaribDA? 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 Water Partnership, etc.). The Association was formed to share experiences, information, operational data, technical standards d and other resources; work together to improve the quality and quantity of 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.

4 Caribbean Desalination History Large L percentage of Caribbean Il Islands are partially ill or fully dependant d on desalination. Desert Islands (ABC s) Little natural storage capacity (on smaller coral islands) Tourism water demands exceed natural capacity High energy costs and harsh operating conditions have made the Caribbean a center for development of desalination, particularly ERD s. 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 s 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

5 Caribbean Desalination History The first know desalination plant in the Americas was in Key West, Florida in 1861 for military use. It produced d27 m3/day in a single effect distillation unit. Source Jim Birkett

7 Caribbean Desalination History The Water & Power Authority of Aruba (WEB) just celebrated it s 80 th year in desal and their Curacao counterpart (Aqualectra) it s 75 th two years ago. The first ME plant in Aruba started operation in 1932

8 Caribbean Desalination History Largest seawater desalination plant in the Largest seawater desalination plant in the Western Hemisphere Ionics started up in 2002 as BOO for WASA 1400 lps (120,000 M3 per day) capacity Very difficult feed water.

9 Recent CaribDA Activity CaribDA held a joint conference together with The Water & Power Authority of Aruba (WEB) to celebrated it s 80 th anniversary in Aruba in June Victoria Vasini of Argentina s Unitek as the recipient i of the Best tpaper Award. Ms Vasini presented A Case Study: Results of Ultrafiltration Compared to Conventional Pretreatment Lifetime achievement award to Dr. Lifetime achievement award to Dr. Jim Birkett.

10 Carbon Neutral Solar Powered SWRO Plant in St. Vincent & Grenadines This World Bank funded project. Implemented by the Caribbean Community Climate Change Center in Belize. 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 dto offset the estimated annual power consumption of the desalination plant. The power from the solar system is being fed to the grid, not directly to the RO plant. This is probably the first attempt in the region to do a carbon neutral desalination project.

11 Delft direct drive windmill unit for seawater desalination at Curacao (Santa Barbara) The combination of windmills and desalination installations is already commercially available. These windmills produce electricity from wind power, the electricity is stored and subsequently used to drive the highpressure pump for the reverse osmosis installation. The storage of electricity in particular is very expensive. Energy is also lost during conversion. Inthe TU Delft installation, the highpressure pump is driven directly by wind power. Water storage can be used to overcome calm periods. The storage of water is after all a great deal cheaper than that of electricity.

12 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 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. 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.

13 Bonaire Plans to Generate 100% Renewable Energy Presently above average 45% renewable energy needs of Bonaire 11 MW wind and 14 MW bio diesel capacity, with iha 25MW 2.5 battery system. Algae derived diesel poject underway for 100% RE. Courtesy of Ecofys Netherlands

14 Geothermal energy project in the Caribbean The European Investment bank (EIB) aims to assess the feasibility of an undersea interconnection between Dominica and Guadeloupe to the north, and a second link with Martinique to the south Geothermal energy can generate electricity through water heated to high temperature by the energy generated in the soil surface. 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 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.
