Belgium Plants 3.5Km of Riverbanks to Naturally Filter Water

The Condroz Regional Action Group (GAL) in Belgium is nearing completion of a natural water purification project using helophytes, aquatic plants known for filtering pollutants, across nine municipalities. Volunteers and students recently planted 700 meters of riverbanks in Tinlot and Clavier, building on work begun a year ago in Nandrin and Modave.

The initiative aims to reduce water pollution by utilizing phytoepuration, where plant roots host bacteria that break down contaminants. These plants also benefit local biodiversity by providing habitat and food for pollinators and wildlife.

The project, inspired by a pilot program in Hannut and Burdinne, is currently three-quarters complete. Remaining work includes planting in Marchin this October and addressing larger, less accessible areas with professional assistance.

GAL Condruses will conduct studies to assess the project’s effectiveness and publish an awareness brochure. The program is scheduled to conclude at the end of 2027.
