    Promoter – Financial Intermediary




    The framework loan will co-finance a specific part of the investment program of Cologne's wastewater utility (Stadtentwässerungsbetriebe Köln) for the period 2023-2029. The pipeline includes the construction of a new culvert under the River Rhine, a new sludge transport pipe, a sludge dewatering facility as well as a sludge incineration facility.


    The aim is to improve the efficiency and sustainability of Cologne's wastewater services. The new combined sewer culvert under the River Rhine will reduce the risk of sewage spills in the river and enable sufficient capacity for the growing population and the increased intensity in precipitation from climate change. The investments in a new sludge transport pipe and a sludge dewatering facility linked to the new sludge incinerator comply with the German requirements on sludge disposal after the energy transition discontinues the current co-incineration in a brown coal power plant. All investments comply with European and German environmental standards. The project will reduce the impact on climate change from wastewater and sludge collection and treatment. Wastewater collection and treatment projects generate positive externalities, including avoided public health costs, environmental benefits of improved water quality and reduced greenhouse gas emissions. Overall, these environmental, climate and social benefits would not be achieved to the same extent without public intervention.

    Environmental aspects

    The investments will contribute to the sustainable management of wastewater infrastructure with overall positive environmental impacts. The project supports compliance with the EU Water Framework Directive (2000/60/EC), the Urban Wastewater Directive (91/271/EEC), EU and national environmental legislation. It will contribute to climate action and environmental sustainability (CA&ES) objectives. Most of the schemes to be financed under the framework loan are expected to have limited environmental and social impacts. However, some may fall under Annex II of the environmental impact assessment (EIA) Directive 2011/92/EU (amended by Directive 2014/52/EU), requiring the competent authorities to determine whether an EIA is required. Where a formal EIA is required, a copy of the Environmental & Social Impact Study or the Non-Technical Summary (NTS) or equivalent document will be provided to the EIB and published on its website. The promoter will also be required to verify that all of the schemes submitted for EIB financing comply with the Birds Directive 2009/147/EC and Habitats Directive 92/43/EEC. For any part of the project that may impact on a nature conservation site, the promoter will be required to provide information on the required mitigating measures to comply with the Habitats and Birds Directive.


    The promoter has to ensure that contracts for the implementation of the project will be tendered in accordance with the relevant applicable EU procurement legislation, Directive 2014/25/EU, as well as Directive 92/13/EEC as interpreted by the Court of Justice of the EU, with publication of tender notices in the Official Journal of the EU, as and where required.
