CETEC expertise and knowledge of new technology drove the in-depth recommendations on WWTP that they provided us. CETEC consulting proved to be the tune up we needed to improve our treated water quality. CETEC is always up to date on the latest technology trends. Their recommendations and insights were always “right on target”. Our WWTP is operating for more than 4 years in good order with the assistance of CETEC in designing and maintaining process.”

Mr. Charles Wickramasinghe Heaven Seven Hotels, Nuwara Eliya, General Manager

I wanted to take this opportunity and appreciate the hard work of the CETEC team has put in getting the treatment plant done in our 7 stories building which currently used as branch of foreign university in Kandy. This was especially challenging due to limited space and due to location of underneath the heavily utilized car parking area.

Mr. Charith Gunasekara Delta Construction (PVT)Ltd. Kandy, Managing Director

I hired CETEC to help us take CEA clearance for our Solar Power Plant project. We had several objectives: shortening the time it took us to get approvals, improving the sustainability of the project by addressing the possible impacts to the environment due to the project, establishing environmental monitoring system for the project. CETEC has a wealth of knowledge in the field of Environmental Assessments and they know how to apply that knowledge in a practical and results oriented way.
