Water Quality Monitoring

Water Quality Monitoring

 

Water quality is monitored over 21 surface water sampling points on a weekly basis using chemical and biological parameters. Eight additional sites on the reservoir are monitored on a weekly basis. In addition, automated water quality stations with satellite data transmission along the Nam Theun, downstream of Nakai Dam, provide real-time information on this stretch of the river.

Water released downstream from the Power Station is monitored at the Regulating Pond and Regulating Dam, plus before and after the Aeration Weir along the 27-km Downstream Channel, in order to gauge the effectiveness of the project's in-built water-quality improvement mechanisms.
