„AGGLOMERATION RIJEKA” PROJECT PREPARATION
Preparation of the study-project documentation (started in 2010.)
• Feasibility study and the project application Jaspers issued The Completion note for the project
• Environmental Impact Assessment of Wastewater collection system Decision on acceptability issued by Ministry of Environment and Energy

RIJEKA GATEWAY PROJECT
Delta area• located in the town center• planned content: main town park, corridor of the main town road and the town railway through Delta, mixed use area (modern
nautical and passenger terminal for accepting ferry boats and cruisers, different commercial, business, cultural and public events),utility and service use area for WWTP location
Existing conditions Delta South The Urban Renewal of the Delta area
NEW WASTEWATER TREATMENT PLANT OF „AGGLOMERATION RIJEKA”
EXISTING WWTP
NEW WWTP
The land on which has been planned to build WWTP Rijeka -> situated on cadastral plots in proprerty of the Republic of Croatia
WWTP Rijeka -> defined by the Spatial Plan of the Primorsko-goranska region and the Spatial plan of the City of Rijeka and the Spatial Plan of the Primorje-Gorski kotar County
Urbanistic solution of WWTP –> defined by Rijeka Gateway Project
Expected contracting works - > end of 2019.
1 year for design, 2 years for construction and 1 year for WWTP test work
Estimated deadline for design: 2019. Estimated deadline for construction and test work: end of 2023.
Existing WWTP (mechanical pretreatment) will be removed form the location
Type of the contract: FIDIC YELLOW BOOK
WWTP capacity: 200.000 PE
WWTP type: SECONDARY TREATMENT
Required surface: 21 880 m²
Surface defined as maritime domain (embankment)
Absence of Sewage Sludge Directive in the Republic of Croatia
Treated sewage sludge from WWTP Rijeka will be transported to the HOLCIM Hrvatska d.o.o. Koromačno
