Fiber Technology Corporation or FTC was incorporated in 1992 in the Commonwealth of Virginia, USA, to provide innovative water storage solutions. The company's founding objective was to design and provide a simple, innovative, globally certified water storage solution by assembling GRP sectional panels in modular and flexible patterns with uncompromising levels of quality and reliability to ensure preservation of water to the highest standards of purity.
A vision of a maintenance-free clean water storage system became the key driver to the product's development. The FTC FRP, also known as GRP Panel type water tanks have become the system of choice around the world to conserve water to the highest quality standards while addressing the shortcomings inherent to traditional storage systems such as plastic, concrete and steel tanks.
We focus our worldwide marketing efforts on the advantage of storing water hygienically for extended periods of time.
Fiber Technology Corporation is an ISO 9001 certified company that manufactures water tanks using the SMC-Hot Press Molding process to the highest specification and hygiene standards. It offers tanks with sizes ranging from 260 USG (1 cu m) to 2,500,000 USG (10,000 cu m) and more, for the direct and indirect water supply markets around the world.
