3 1. Background The supply and availability of reliable potable water in small island developing states has and continues to be a major challenge to address. A sustainable water supply plays a crucial role in the development of a people, and as such the island of Carriacou is included in the process of allocation of the important resource. The Island of Carriacou has a population of approximately eight thousand (8000) people based on the 2011 National Population Census. Until early in 2016 Carriacou was without a consistent supply of potable water to suffice both domestic and developmental demands. Its people depended primarily on rainwater harvesting to meet this essential need. There are no permanent lakes or streams that can provide a reliable or significant quantity of fresh surface water to meet potable water demands (Burnside May 2012). In April of 2016 the CCCCC completed the installation of a SWRO Desalinization plant powered by a Photo Voltaic Renewable Energy System that provides potable water to the main town of Hillsborough and surrounding areas. The project was funded jointly by UKDFID and EU-GCCA. The SWRO and distribution systems were funded by the UKDFID at a cost of approximately US$750,000. The Photo Voltaic (PV) renewable energy system for powering the SWRO plant, storage tanks, and force mains were funded by the EU-GCCA at approximately US$500,000. Under this proposed project a similar system will be installed to provide potable water for the remaining rural areas of the island. A brief description of the Hillsborough system is provided below. The system is a scaled up replication of a pilot demonstration system installed by the CCCCC in the neighbouring island of Bequia in the Grenadines in The Hillsborough system consists of: 1. A salt-water reverse osmosis plant powered by a photo voltaic system capable of producing 300 m 3 /day (79,251 US Gallons/day) with a quality that exceeds the WHO standard. 3

Motivation It is well known that Salt Water Reverse Osmosis (SWRO) systems require large amounts of energy for its operations. To mitigate the use of fossil derived energy to power the SWRO a design, using a grid-tied Photo Voltaic system, was tested by the CCCCC through a pilot project in the island of Bequia in The design removed the need to have the SWRO and PV system co-located. In addition excess energy produced by the PV system could be sold to the grid through a net-metering arrangement. The revenue derived through this means help to support longterm operations of the SWRO. The pilot project was very successful. It demonstrated a number of worthwhile outcomes namely: It can provide greater energy and water security for water scarce small islands such as Bequia. The modular design is easily expanded to meet growing community demand. It provides a baseline for assessing the effectiveness of replicating it on other Small Island States. Similar systems have since been successfully replicated and scaled-up in Carriacou and Petit Martinique, neighbouring islands in the Grenadines. 6

7 3. Aims of the Project The aim of the project is to expand the system that has been installed so that potable water can be made available throughout the island of Carriacou. The expansion of the system: 1. Will increase the island s resilience to withstand periods of extended drought as a result of Climate Change and also to recover quickly in the aftermath of any natural disasters like hurricanes, to which it is vulnerable; 2. Will create employment, not just in the initial stages, but has the potential to create incremental employment as the demand for potable water increases in the future; 3. There is also the likelihood of revenue generation from excess electricity being sold back to the national grid, as solar energy will be used to generate energy for the operation of the SWRO plants; 4. Most importantly this project will deliver potable water to over 4,000 people throughout the remaining communities of Carriacou. The health and wellness of the people is essential and invaluable to the island continued development, as such the supply of potable water will reduce in the likelihood of incidence of water borne diseases outbreaks 4. Technical Description The system will comprise of the following components: i. A Salt Water Reverse Osmosis (SWRO) system with a capacity of producing 300 m 3 /day (79,251 US Gallons/day) with a quality that exceeds the WHO standard. ii. A grid-tied Photo Voltaic system with a capacity of producing 150 Kw iii. A water storage system capable of storing 100,000 gallons of water iv. A water distribution system with home connection capability 7

9 5. Strategy for international support and identification of possible co-funders As indicated the Hillsborough SWRO/PV system was co-funded by the UKDFID and EU-GCCA. The expansion system being proposed is expected to be co-funded jointly by Italy and the United States through its Agency for International Development (USAID). The co-funding will be provided by USAID under its Caribbean Climate Change Adaptation and Risk Reduction Initiative (CCCARRI) project being implemented by the CCCCC. 6. Economic and social impact The economic and social impacts of this project over the long term will be instrumental towards the entire developmental process of these islands. 1. This will improve the standard of living and health throughout communities through the sustainable supply and access to potable water. 2. There is a potential for increased business start-ups and major developmental projects in important sectors such as tourism, manufacturing, agriculture and agro processing. 3. The overall health of the population will continue to increase, thus creating avenues for savings in the area of health prevention and treatment 7.
