DEVISE ENGINEERING S.A. specializes in the field of environmental technologies. The company’s main activities are the design, engineering and manufacture of “Smart Package Plants” for the treatment of Water and Wastewater.

DEVISE ENGINEERING S.A. has developed some very innovative systems of a compact and pre-fabricated format which are an excellent solution for the sewage treatment of small communities and municipalities, while they can be a unique alternative to the wastewater treatment of industrial effluents.

DEVISE offers its clients a high standard of services and always strives to find the most optimum solution to their environmental concerns. The ISO 9001:2008 Quality Assurance Certificate that the company holds for the Design, Construction and Maintenance of Water & Wastewater Treatment Systems is a reassurance that our clients will get a product of high quality at the best value money can buy.

The construction and testing of company’s own make products (pre-fabricated plants) takes place in the Mandra warehouse and at selected associated steel subcontractors, while the quality of manufacturing is closely monitored at all stages, according to the ISO Q.A. system.


By continuous Research & Development using the most up-to-date methods of CAD/CAM in engineering and design and by integrating innovative technologies for wastewater treatment (M.B.B.R. & M.B.R) we achieved the production of packaged systems with high performance and low operating costs. The manufacturing standards of these ‘smart packaged plants’ conform to internationally recognized specifications (BS, DIN, CE) while the treated effluent quality meets the European and international effluent discharge standards. 

The company has a significant presence in Europe (Greece, Ireland, Poland, Bulgaria, etc) and through achievements of high plant performance it gained total customer satisfaction. Therefore, the company is experiencing a large increase of business activity in many other regions such as the CIS, the Middle East and North Africa.

We are striving to reach this goal by manufacturing quality products and providing efficient technical solutions and services.
