Four-star hotels and resorts consume much water
and discharge more waste as compared to the others.
Wastewater treatment in hotels is not yet a common
practice in Vietnam. Very few surveyed hotels and
resorts have installed wastewater treatment or/and
recycling systems; most of them discharge their wastewater
directly into municipal drainage system, rivers
and sea, causing bad odor and pollution. Many hotel
managers, who are aware of the need for wastewater
management, are still reluctant to make decisions on
investment in wastewater treatment due to its high
cost. However, hotels and resorts in coastal region
have started showing concern for wastewater management
due to the new environmental laws, tourist heritage
and sustainable tourism goals.
