In July 2016, Mekorot opened a new sewage treatment plant in the Romanian city of Roman. The plant treats sewage from the area’s urban and rural environments.

The sewage treatment plant’s expansion and improvement was carried out by Mekorot’s subsidiary, Mekorot Development & Enterprise, and included the construction of new sewage treatment facilities and the replacement of all electro-mechanical equipment. The company was also responsible for managing and monitoring local contractors and equipment suppliers from across Europe. All work on upgrading and expanding the sewage treatment plant was carried out without disrupting its regular, day to day operation. From start to completion, the project which was valued at some 10,000,000 euro, took just 18 months. ​
