OSTAR went on to acquire shares in a specialized water treatment company called WETICO (previously known as Saudi Berkefeld Filter Co.) in 2001.


WETICO’s history is mainly that of Saudi Berkefeld Filter Co Ltd which was based in Riyadh, Saudi Arabia. The Company is involved in the design, manufacturing, installation and servicing of Water, Sewage and Wastewater Treatment Plants. Saudi Berkefeld was a joint venture between a local Saudi company and Sterling Berkefeld Filter Germany. This joint venture was established in 1990, although the partnership had been operating for more than 20 years.

During this time WETICO was unable to return a sizeable profit and in 2001, OSTAR bought the German shares of the company (changing the name to WETICO) and under OSTAR’s direct involvement utilizing our PDS technique, WETICO was able to increase its revenue more than 10 times in less than a decade. At present WETICO is the largest water and wastewater treatment company in the Middle East with several offices and precense the MENA region.
