“The collection of data to control liquid waste [sewage] in five provinces, that is Kompong Chhnang, Pursat, Battambang, Siem Reap, and Kompong Thom, was started to be implemented by the Ministry of Environment for the first time in order to prevent the flow of sewage into the Tonle Sap Lake.

“An official of the Department of Environmental Pollution Control of the Ministry of Environment recently said that the collection of data on liquid waste in the five provinces around the Tonle Sap Lake is a task that needs to be clearly implemented. The start to collect data on sewage in the five provinces will monitor the flow of liquid waste from populated areas as the major goal.

“Mr. Heng Nareth, the director of the Department of Environmental Pollution Control of the Ministry of Environment, said that pollution by liquid waste originates from the citizens’ houses, and from factories and workshops.

“He added that it is estimated that waste from factories and from workshops is less than expected, that is between 5% and 10% only, while the pollution from people’s houses is between 90% and 95%.

“He explained that the pollution by liquid waste from citizens’ houses causes damage to the environment of the Tonle Sap Lake’s water when the number of persons in populated areas increases from year to year. Domestic waste is bio-pollution, because that liquid waste contains nitrogen, phosphor, and other chemicals that can kill living species in the natural water resources.

“The departments’ officials said that the liquid waste from factories is less in volume and much easier to control than liquid waste from households. Nevertheless, environment officials of the five provinces will try to find data about the liquid waste at the end points of sewage system pipes and at relevant population concentrations in inhabited rural areas and in towns.

“According to estimations from expert environmental officials, 70% of the citizens’ domestic water use goes into sewage, and 30% might infiltrate into the ground. As for the liquid waste of the five provinces, after collection of data on the quantity of domestic water use is completed, following soon there will be measures established for cleaning of the sewage water before it is released, in order to avoid polluting the natural water of the Tonle Sap Lake.”
