About Us


Caribbean Water Treatment Ltd. was incorporated in August 1992 under the Companies Act of Antigua & Barbuda. It is a privately held, 100% Antiguan owned corporation. Since the doors opened on October 1 1992, the company has grown locally and regionally to become a leading provider of water and wastewater treatment services in the Eastern Caribbean.

In 2006, the company separated its growing swimming pool business into a wholly owned subsidiary called CWT Caribbean Pools Ltd. CWT Caribbean Pools Ltd. is the leading swimming pool construction and maintenance company in Antigua, and also provides its services in other Easter Caribbean islands.


In 2013, the company moved from its original location on Lower Dickenson Bay Street in St. John’s. Our new 11,000 square feet facility is located at Friars Hill, St. Johns, Antigua housing a retail store, offices, warehouse and specialized chemical storage rooms.


The company’s founder and managing director, Mr. J. Mario Bento, has over 30 years of experience in water treatment in North America and the Caribbean. He holds a Bachelor of Applied Science degree in Chemical Engineering from the University of Toronto and a Masters in Environmental Systems Engineering from McMaster University in Canada. 


In addition to work-terms at ESSO Chemical in Canada and the Antigua Public Utilities Authority (APUA) Crabbs Desalination Plant, Mr. Bento also worked four years as a process development engineer for Zenon Environmental Inc. in Canada, a worldwide leader in the development and manufacture of membrane based systems for water and wastewater treatment. 


At Zenon, Mr. Bento managed process development projects for several large industrial clients across Canada and the U.S., including IBM, Maxwell House, Procter & Gamble and Kraft General Foods.
