Water Recycling Project

The Luang Prabang Hydropower Project has implemented a water recycling system at its batching plant. This system reuses water for key activities, including aggregate cooling (reducing rock temperature), cleaning the concrete mixing plant, and washing concrete transport trucks, with a total water usage of 1,430 cubic meters per day. To minimize water waste, 1,200 cubic meters per day of used water is pumped back into the process, leaving 230 cubic meters per day for additional uses. The remaining water is used for cleaning the plant and trucks and spraying roads to reduce dust from traffic within the project site. In total, the project reuses 83,950 cubic meters per year (or 83,950,000 liters per year), significantly reducing reliance on natural water sources and minimizing wastewater discharge into the environment. The water recycling initiative officially began in January 2023.
