Enhancing local government management of wastewater issues in the Phetchaburi River at Khlong Khachen subdistrict

บทคัดย่อ

Water pollution in Phetchabun province has significantly impacted the local economy, environment, and quality of life. A survey conducted in 2017 revealed that the Phetchaburi River was severely polluted, with a Water Quality Index (WQI) ranging from 31 to 60 and dissolved oxygen (DO) levels below acceptable standards. Key contributing factors include domestic wastewater discharge directly into the river and the construction of weirs obstructing water flow. Approximately 200 households were found to be encroaching on the riverbanks, with most having septic tanks that discharged directly into the river. Additionally, concrete roads and bridges served as barriers to water flow. To address these issues, the relocation of toilets and septic tanks away from the riverbanks has been proposed. River restoration efforts have been supported by the community and relevant agencies, including water management, weed removal, and community engagement. Collaborative efforts and inclusive participation have been crucial for river restoration. Through effective collaboration, the Phetchaburi River can be revitalized and sustainable development can be achieved.
