Waste and water management in Chhnok Tru, Tonle Sap

Waste and water management on the Tonle Sap


Chhnok Tru Village is one of six fishing villages in Kampong Chhnang Province located near the mouth of the lake connecting to Tonle Sap River. The village has a total of 1,761 households, and is divided into 3 ethnic groups – Khmer, Cham and Vietnamese. Following the success of one of the project on “Waste” during a field investigation module in Sept 2016, a team of 4 from NUS Geography, along with 4 Environmental Studies students from PUC returned to the village under the project titled ‘Waste on Water’ from in 2017 (this abstract is taken from an article written by a NUS student)

Today, this project is involving more stakeholders and partners with the common goal of raising environmental awareness and sharing practical ways to manage wastes better. There is a recognition that government involvement is needed to implement better waste management systems.

Areas of work:

  • Environmental education for students in the Khmer, Cham, and Catholic School: up-cycling workshops using plastic wastes found on the Tonle Sap;
  • Installing waste bins in the school compound – the issue with this is that there still isn’t a waste collection system in place in Chnnok Tru, if not in most parts of the Tonle Sap floating community. More work with the commune and provincial government is required 
  • Installing portable water filters in key social nodes: schools, public hospital. Monitoring of the usage and interviews to understand trends in water consumption is currently done by WateRoam and a student from Pannasastra University of Cambodia.
  • Further engagement with students are in the works

Partners involved in this project: 

  1. National University of Singapore’s Geography Department: Chnnok Tru is a field investigation site for a Level 3000 module. The students’ research on the waste issue in 2016 has helped pioneered this project. The field investigation module will return to Chnnok Tru in late 2018.
  2. Pannasastra University of Cambodia’s Environmental Science Department is crucial to the execution of the project. Ratana Kheng, Dany, and Pisey, recent graduates of the department have developed strong relationships with the community, and are important young Khmer leaders to help create change.
  3. Actxplorer has participated in a few trips – contributed to the teaching materials and lessons with the schools, and purchase of a WateRoam kit.
  4. WateRoam demonstrated how the FilterPlus works and steps to maintain the kit with key village leaders and the community as well. It hopes to introduce a micro water entrepreneurial business model to a few families in an upcoming trip in May 2018.

This is an ongoing project.
