About Us
Founded in 1982 by Önder Çeri, Önder Çeri Engineering has become one of Turkey’s leading companies in the water and wastewater treatment sector. Over the past 40 years since its establishment, our company has completed hundreds of projects on both an individual and corporate scale, serving a wide range of clients from municipalities to private sites, factories to universities in different regions.
Our founder Önder Çeri’s knowledge and vision have now been taken over by second-generation representative Ulaş Çeri, who is taking our company forward. With the confidence that comes from being a family business, we combine our years of experience with modern engineering solutions to implement new projects both in our country and in neighbouring countries.
Our company has earned the trust of the private sector by constructing hundreds of biological and chemical treatment plants and swimming pools in the past; in recent years, it has turned its focus to public projects and government tenders. Today, we construct infrastructure and treatment plants for municipalities and public institutions, completing our projects to international quality standards.
As of 2025, we have implemented important projects for the municipalities of Trabzon, Eskişehir and Altıntaş, as well as for the General Directorate of Highways. Independent analyses conducted by Yeditepe University confirm that the water produced by our facilities meets global standards, scientifically proving the success of our engineering solutions.
