WP2.1.3: Support for large scale investments in infrastructure and climate resilience – water treatment plant of Novi Sad

Novi Sad

Objectives

The aim is to demonstrate the added value of the climate services and risk information generated in WP2 beyond the insurance sector, viz. to support adaptation decision making in the public and investment sectors.We will do this on the example of a planned large infrastructural investment in the Danube basin, a new waste water treatment plant for the city of Novi Sad, the second largest city in Serbia. It is worth noting that the implementation of the treatment plant is on the list of the Serbian investment plan for the EU Instrument for Pre-accession Assistance (IPA II)

Description

The Future Danube model suite and OASIS Loss Model Framework will be applied to support the design of the planned waste water treatment plant of Novi Sad. The Pre-Feasibility Study (PFS) for the Novi Sad Wastewater Treatment Plant (WWTP) has been prepared within the Western Balkans Investment Framework (WBIF) as the main output defined within the approved Project Grant Application Form (PGAF) coded TA3-SER-ENV-01. The PGAF identifies following phases in the preparation of the documentation for the Novi Sad WWTP: 

  • Elaboration of the PFS with Conceptual (General) Design;
  • Elaboration of the Feasibility Study with Preliminary Design;
  • Preparation of the Environmental Impact Assessment Study;
  • Preparation of the Tender documents using the FIDIC1 Yellow Book.

The Future Danube model suite and OASIS LMF Loss Model Framework will be applied in the second phase of the documents preparation process, in order to support the design of the planned WWTP of Novi Sad, which is on the list of the Serbian investment plan for the EU Instrument for Pre-accession Assistance(IPA II). Wastewater treatment plants are heavily affected by intense precipitation, resulting in flash floods, and by too high river water levels, which are expected to become more severe in the future (Hattermann et al. 2014). Thus, for the safety of operations, it is essential to ensure their climate resilience i.e. that their capacity and technology is adapted to possible extreme events under current and climate change conditions.

A serious problem is for example that floodwaters are usually contaminated with infectious microorganisms. In addition, floodwaters may also contain agricultural or industrial chemicals and hazardous agents present at flooded hazardous waste sites. Water contaminated with microorganisms, organic/inorganic chemicals and trace pollutants can heavily affect wastewater treatment plants, residential septic systems and municipal sanitary sewer systems during and after the flood event.

The investigation will further follow the non-paper of the European Commission called ‘Guidelines forProject Managers:

Making vulnerable investments climate resilient to current climate variability and future climate change’. FTNis preparing the feasibility study for the investment, and PPISwill apply the guidelines of the Commission. The guidelines define 7 modules to assess vulnerability and adaptation options while planning and executing the project.
