Our company was established in September 2009 under the name Professional Foundation Company (PFDN). The initial purpose of the company was to integrate experts in different fields to combine and facilitate their specialties to build a professional team for energy management. The company’s activities started with engineering works including building materials, handling and waste water management.

As the activities of the company largely involved around water management field, Mr. Pinai Puangmanee (Founder & CEO) decided to change the name of the company from Professional Foundation (PFDN) to International Water Management Co., Ltd. (IWM) in 2015.

Over a decade, IWM has gradually become a leading water management company in Thailand.
