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
