The complementary program supports a variety of investments in wastewater disposal, focusing on energy and resource efficiency, flood and heavy rainfall protection, and adaptation to climate change. It also includes measures to reduce pollutant discharges and treat mixed and rainwater.

Type and Scope of Funding

This program offers low-interest loans as supplementary financing. The funding amount can be up to 5 million Euros and cover up to 100 percent of the eligible investment costs. The loans have a long term and fixed interest rates.

Conditions and Requirements: Funding Guidelines and Obligations

Specific conditions apply for funding under the NRW.BANK.Complementary Program.Wastewater, particularly the simultaneous application for a loan or grant from the ZunA NRW Program and compliance with the NRW.BANK's ESG funding requirements. The project start before application is also relevant.

Application Procedure

The application for the NRW.BANK.Complementary Program.Wastewater must be submitted to NRW.BANK. The procedure varies depending on whether it is combined with a loan or a grant from the ZunA NRW Program. After a positive review, a global commitment is made, and disbursement occurs after construction begins.
