TSG MAKING EVERY DROP COUNT TSG Water Resources (USVI), Inc. February 19, 2016 Mr. Richard Kahn HBRK Associates, Inc. 575 Lexington Ave., 4th Floor New York, NY 10022 Dear Mr. Kahn, Subject: Water Supply Options for Great St. James Island On February 9, TSG visited the island and assessed the existing conditions as regards water supply. Our findings and recommendations are contained herein. The island at present only has one main, 3 bedroom residence and a small caretaker's cottage on the hill above the main residence. A small pool and deck are located on the hillside between the caretaker's cottage and the main residence. Existing facilities: At present, a small Marine sized RO plant is located on the island in an 8 X 10 foot shed near the main house. It is a Tomar SW-500 unit and is assumed to be designed to produce 500 gallons per day (GPD) on house current of 120/240 voltage. It is fed seawater from a 1.5 inch diameter pipe located under the existing dock and pumped up to the plant by a 2hp pump located at the corner of the tennis court. It was not operational at the time of our visit and a former caretaker of the property who was onsite that day stated that he had never seen it running. A small, oval shaped, above ground cistern is located behind the RO plant shed. This cistern is estimated to hold about 6,000 to 7,000 gallons and only had a few inches of water in it. The main residence has a cistern located under the master bedroom pod that was measured at approximately 24 ft long by 15 ft wide by 6 feet deep and has a capacity of about 17,000 gallons. It had about 5 feet of water in it at the time of the survey and is likely replenished by rainfall. Two other smaller cisterns were located on the hillside above the house and only hold about 500-600 gallons each. The caretaker's cottage has 3 separate plastic tanks of similar capacity and are fed St. Thomas Corporate Offices 6501 Red Hook Plaza Suite 201 St. Thomas, VI 00802-1306
