Xylem wins fish pass pump contract for Laos hydropower dam

The pump contract is the largest Xylem project in the ASEAN region to-date.

The US$3.5 billion hydropower dam allows water to be kept within the river’s course and minimally raises the water level to allow fish migration between the Upper and Lower Mekong, while providing electricity to about 4 million people in Laos and Thailand. A number of independent fish passing facilities are included in the design of the dam to accommodate the more than 200 species of fish that inhabit the site for spawning and/or dry-season refuge.

Xylem’s Flygt AC series customized column pumps have been designed to match the specified pump configuration, hydraulic and materials requirements, to be used to help facilitate fish migration through or around the hydroelectric power dam structure and mitigate the ecological impact.

“The collaboration between the Xylem team, local subcontractors and project consultants, coupled with the customized design of our large Flygt Pumps, were key success factors in securing this contract,” said Allan Hendry, vice president and regional director for Xylem Greater Asia.

Construction of the hydropower dam began in 2012, with commercial operation set for 2019.
