ZAGREB -CAPITAL OF CROATIA, EU
• CROATIA - 5 Mio Inhabitants• 55.000 km2 • 34.000 km2 Adriatic sea• GDP/capita < 20.000 USD
• Zagreb 1 Mio Inhabitants• 3000 km of wss• 2000 km of sewage• WWTP 1,2 (1,5) Mio PE• River Sava dividing city in 2
• I PHASE- DATA COLECTING AND EVALUATION– GIS– Monitoring campaign– Model building and calibrating– Evaluation of existing situation
• II PHASE – MASTER PLAN– Short term measures– Long term measures– RTC– Water quality modeling
• III PHASE – DESIGNING GOK (MDC) SYSTEM• IV PHASE –DETAIL DESIGNING AND CONSTRUCTION

ZAGREB SEWER SYSTEM PROJECT
FROM MASTER PLAN TO OPERATION
(1995. – 2007.)
• V PHASE- OPERATION– Major construction works finished– WWTP in operation– Further sewerage system rehabilitation plan slowered – Climate changes effects
• VI PHASE – SCADA PROJECT– Provision of monitoring equipment (rainfall runoff) – Monitoring campaign– SCADA project
• VII PHASE – BLUE GREEN APPROACH– Water quality monitoring– Preparation for BGD

FROM TRADITIONAL TO BLUE GREEN SOLUTIONS
-Traditional solutions could not compensate for the climate change impact due to various reasons partly due to uncontrolled urbanisation
-Frequent urban floodings caused substantial damages to the urban infrastrucure, properties and human lives
- EU directives to be followed push desicion makers to undertake improvements on the sewerage systems

SCADA / GIS SYSTEM
-rainfall runoff monitoring
-Establishment of the SCADA system
- Qulity monitoring
-- Further enlargment of the SCADA system with WQ parameters
-- Blue Green designing
-- Water and energy savings

CONCLUSIONS – LESSONS LEARNED
STRUCTURAL MEASURES, BEING TRADITIONAL APROACH ARE IN URBAN AREAS EXPENSIVE AND CAN NOT ACCOMODATE FOR EFFECTS OF CLIMATE CHANGES
NON-STRUCTURAL MEASURES ARE HELPING IMPROVING OVERALL PERFORMANCE OF THE SS
GIS / SCADA FURTHER IMPROVES SS MANAGEMENT
BLUE GREEN CONCEPT FURTHER IMPROVES WATER / ENERGY CYCLE IN CITIES BALANCING INPUTS AND OUTPUTS, ENABLING SUISTAINABLE FUTURE
COMBINATION OF STRUCTURAL AND NON-STRUCTURAL MEASURES SUPPORTED BY BLUE GREEN CONCEPT WILL ALOW THE MOST BALANCED MULTICRITERIAL SOLUTIONS
BY IMPLEMENTING COMBINATION OF STRUCTURAL , NON-STRUCTURAL AND BLUE-GREEN MEASURES ONE CAN ACHIEVE HIGHER URBAN STANDARD, HIGHER SECURITY AND LOWER O/M COSTSProning DHI d.o.o.
