NWT provided the consulting services for studies for 8 medium-sized cities in Serbia within a KfW-funded project for the rehabilitation and construction of sewerage systems and wastewater treatment plants.

The project includes the rehabilitation of the wastewater sewerage system, the stormwater system, the associated pumping stations and 7 new wastewater treatment plants with sizes ranging from about 50,000-150,000 ECW.

From the feasibility studies, tenders will be prepared based on the FIDIC Red-book for the sewer system and on the Yellow-book for the WWTPs.
