Ecosystem Restoration of Rangsit Canal for Sustainable Water and Environmental Management

Faculty of Public Health , Chalermphrakiat Sakon Nakhon Province Campus

Details

This project addresses water pollution and contaminated sediments in the Rangsit Canal, a waterway critical for surrounding communities and large-scale agriculture in Pathum Thani. The research team began with a comprehensive assessment of water and sediment quality, analyzing pH, dissolved oxygen (DO), organic matter content, and heavy metal concentrations to establish the ecological baseline before intervention.

Based on this assessment, the project developed a restoration plan combining phytoremediation using aquatic plants—such as controlled water hyacinth, Cyperus, and cattails—with the installation of low-energy Venturi Jet aeration systems to increase dissolved oxygen continuously. The team also engaged more than 10 local schools through “canal-side classrooms,” cultivating environmental awareness and water stewardship among students and community youth.

First-year outcomes included a 30% reduction in BOD levels in the pilot stretch, a visible increase in local fish biodiversity, and enhanced community use of the canal for household and recreational purposes. A restoration manual was also published for replication in other watersheds. The project aligns directly with SDG 6 (Clean Water and Sanitation) and SDG 15 (Life on Land).
