About Us


Founded in 2009 by the benign efforts of Chandrasekaran. J, an expert in Plastics Technology, the proprietary firm “Custom Parts Online” started making many innovative products to address the soaring needs of common people.

Under the license from IMMT (CSIR), Bhubhaneshwar in the year 2010 by Custom Parts Online, the poor man's water purifier, popularly known as ‘CPO Natural Terafil®™ Water filter’ was manufactured which was later exclusively run by WATSAN Envirotech Private Limited. Later in 2013, Mr. P. N. Subramanian, an IT Professional with 35 years of experience in HR, Strategy & Planning headed WATSAN as the Co-founder.

The name WATSAN was coined by blending the words ‘Water’ and ‘Sanitation’, which are the two main aspects of our establishment. WATSAN’s sole purpose is to provide water and sanitary solutions to the rural population by manufacturing and distributing low-cost, yet effective electricity-free water filters to urban slums and rural families who cannot afford other expensive options.
