CONSOLIDATED WATER CO. LTD. REPORTS 17% INCREASE IN FIRST QUARTER EARNINGS

COMPANY DECLARES SECOND QUARTER CASH DIVIDEND

GEORGE TOWN, Grand Cayman, Cayman Islands (May 10, 2007). Consolidated Water Co. Ltd. (NASDAQ Global Select Market: “CWCO”) today reported record quarterly revenues and earnings for the three months ended March 31, 2007. The Company also announced the declaration of its quarterly cash dividend.

Net income for the first quarter of 2007 increased 17% to $3,587,478 ($0.25 per diluted share), compared with net income of $3,078,011 ($0.24 per diluted share) in the first quarter of 2006.

“We are pleased to report higher revenues and earnings for the first quarter of 2007,” stated Rick McTaggart, Chief Executive Officer of Consolidated Water Co. Ltd. “We generated more gross profit dollars this quarter as compared to last year’s first quarter due to growth in our bulk revenues and our plant construction and expansion activities. However our gross profit percentage declined for this quarter when compared to the first quarter of 2006 due to a change in relative revenue mix, as our bulk and services operations generate a lower relative gross profit as a percentage of sales than our retail operations.

Our new Blue Hills plant in Nassau, Bahamas, contributed $1.7 million in water sales during the first quarter of 2007. However, margins for this plant continue to be affected by a requirement under our contract to provide the government water utility with free water until we complete the requirement under the Blue Hills contract to reduce the water lost by the public water distribution system on New Providence. We continue to believe we will meet this requirement before the end of this year.

Revenues and gross profit from the services segment increased due to revenues earned on the construction of the plant at Tynes Bay on the northern coast of Bermuda and the expansion of the North Sound plant on behalf of the Water Authority — Cayman. The North Sound expansion was commissioned in April 2007 and the construction of the Tynes Bay plant is proceeding on schedule,” concluded Mr. McTaggart.

Total revenues for the three months ended March 31, 2007 increased 38% to $12.7 million, compared with $9.2 million in the three months ended March 31, 2006. Retail revenues were relatively unchanged at $5.1 million for the three months ended March 31, 2007 and 2006. Bulk revenues rose 39% to approximately $5.2 million in the most recent quarter, compared with approximately $3.8 million in the corresponding quarter of the previous year. Services revenues increased significantly to approximately $2.4 million in the first quarter of 2007 versus approximately $441,000 in the three months ended March 31, 2006.

Consolidated gross profit increased to approximately $5.3 million (42% of revenues) in the three months ended March 31, 2007 versus approximately $4.8 million (52% of revenues) in the year-earlier period. The gross margin on retail revenues approximated $3.3 million (65% of revenues) in the most recent quarter, versus approximately $3.6 million (71% of sales) in the three months ended March 31, 2006. The gross margin on bulk revenues improved to approximately $1.3 million (26% of revenues) for the three months ended March 31, 2007, compared with approximately $832,000 (22% of revenues) in the three months ended March 31, 2006. The gross profit on services revenues approximated $624,000 and $337,000 for the three months ended March 31, 2007 and 2006, respectively.

General and administrative expenses increased to approximately $2.3 million in the first quarter of 2007, versus approximately $2.1 million in the 2006 prior-year quarter.

A substantial portion of the Company’s interest costs were capitalized as part of the construction cost of the Blue Hills plant during the quarter ended March 31, 2006. The Company ceased capitalizing interest when the plant was commissioned in July 2006 and, consequently, the Company’s interest expense increased to approximately $481,000 in the most recent quarter, compared with approximately $215,000 in the corresponding period of the previous year. The Company benefited from the investment of the unused proceeds from its recent public offering during the quarter ended March 31, 2007, earning interest income of $449,000, or approximately $420,000 more than the interest income for the 2006 quarter.

The Company also announced that its Board of Directors has declared a quarterly cash dividend of $0.065 per share, payable May 31, 2007 to shareholders of record at the close of business on April 30, 2007.
