Existing conditions Delta South The Urban Renewal of the Delta area
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 NEW WASTEWATER TREATMENT PLANT OF „AGGLOMERATION RIJEKA”
NEW WWTP
EXISTING 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 General information
Urbanistic solution of WWTP –> defined by Rijeka Gateway Project Type of the contract: FIDIC YELLOW BOOK
Expected contracting works - > end of 2019. WWTP capacity: 200.000 PE
1 year for design, 2 years for construction and 1 year for WWTP test work WWTP type: SECONDARY TREATMENT
Estimated deadline for design: 2019. Required surface: 21 880 m² Estimated deadline for construction and test work: end of 2023. Surface defined as maritime domain Existing WWTP (mechanical pretreatment) will be removed form the (embankment) location
SLUDGE MANAGEMENT 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 WASTEWATER TREATMENT PLANT OF „AGGLOMERATION RIJEKA” VISUALIZATION ACCORDING TO THE CONCEPTUAL DESIGN
New WWTP BENEFITS OF EU PROJECT:
Compliance with the Urban Wastewater Treatment Directive Grants in the amount of 1,25 billion HRK Higher utility standard Clean environment and protected drinking water Reduced losses and improved efficiency of the water supply system
Existing connection rate SITUATION AFTER EU Connection to the public sewer PROJECT system for approx. 92% of population 68 % Thank you very much for the attention!
