Project Description

Proposed design, construction, operation and maintenance of the first waste-water treatment plant for the city of Zagreb on a Build Operate Transfer (BOT) basis for 28 years. The project would also include the construction (but not the design or operation) of supporting infrastructure, including an access road, collecting pipeline, cover for a drainage canal, and a bridge across the river Sava (with pipeline).
Objective: To permit the city of Zagreb to treat municipal waste water to comply, in stages, with EU standards.

Transition Impact

The project introduces the private sector to the provision and financing of municipal waste-water services through a process of full international competitive bidding.

The Client

The borrower is Zagrebacke Otpadne Vode d.o.o., a special-purpose, limited liability company incorporated in Croatia and owned by a sponsor consortium consisting of RWE AQUA GmbH (owned indirectly by RWE AG) and SHW Hölter Wassertechnik GmbH (fully-owned subsidiary of Berlinwasser Holding Aktiengesellschaft).

EBRD Finance

The EBRD would provide senior debt of  €55.2 million (with co-financing from another bank).

Project Cost

€270 million.

Environmental Impact

This project was screened A/0 under EBRD’s 2003 Environmental Policy, requiring an environmental impact assessment (EIA) for the proposed investment project. An EIA study was carried out by an independent local consultant.
The findings of the EIA indicate that some environmental impacts will be caused by civil engineering works, such as higher noise levels, dust caused by soil excavation and management and disposal of excavated soil and waste. These impacts will be temporary and will be managed by applying international good working practices.
Once the waste-water treatment plant is completed, its operation will cause limited local impacts such as aerosol emissions, odour and noise, and will require adequate provisions to prevent chemical spills and to ensure adequate sludge management. Relevant mitigation measures are proposed and will be implemented during construction, start-up and subsequent operation and maintenance of this facility.
There is an Environmental and Social Impact Assessment available for this project.
A monitoring visit has been carried out by the EBRD and external consultants in May 2011 to assess environmental, health and safety performance and compliance of the project and Company’s operations and facilities. The visit confirmed that the site is well managed, there is a good awareness of environmental, health and safety issues, and the overall the facility is managed in line with EBRD’s policy requirements. Finding a permanent, sustainable solution to the sludge storage issue is a significant challenge that must be addressed, and the Company is working together with the City to find a solution.

Following the visit a number of recommendations have been made for further improvement in the areas of sludge management and the need to implement a long-term sludge disposal strategy, improvements to occupational health and safety procedures, stakeholder engagement practices, and environmental and social reporting. These findings and recommendations have been discussed with the Client for their follow up.
