Native title of the NBS intervention
Budowa i przebudowa kanalizacji deszczowej i dostosowanie sieci kanalizacji deszczowej do zmian klimatycznych na terenie miasta Bydgoszczy
Short description of the intervention
The city of Bydgoszcz modernizes the rain drainage system with the support of EU funds. The current badly functioning rain drainage system (with sanded and littered canals) prevents from unobstructed rainwater flow to the Brda and Vistula Rivers or the Bydgoszcz Canal. This in turn leads to frequent floods in the city. The project is planned for the period between 2017 and 2021 and involves water purification and management of rainwater in the grey and green urban areas as well as reuse of the collected water for watering urban greenery [1,2].
