Tu Cau pumping station is contaminated with salt, hydropower plants are requested to increase water discharge.

On August 5, Vu Gia - Thu Bon Irrigation Branch (under Quang Nam Irrigation Exploitation Company Limited) said that recently, saltwater has frequently intruded into the suction tank of Tu Cau pumping station with an average of 7-15 hours of saltwater intrusion per day, with the highest salinity being 2.3 parts per thousand.

Currently, the unit still regularly monitors salinity on Vinh Dien River and at the pumping stations of Tu Cau, Cam Sa, Vinh Dien (hourly monitoring) to operate the saline bypass pump to ensure irrigation water for 2,000 hectares of agricultural land in An Thang, Dien Ban, Dien Ban Dong, and Ngu Hanh Son wards.

However, with the prolonged hot weather, the water source downstream of Vu Gia - Thu Bon river is decreasing combined with high tides, Vu Gia - Thu Bon Irrigation Branch believes that the risk of salt water continuing to intrude and maintain a high concentration in the suction tank of Tu Cau pumping station. At the same time, it will intrude deeply into Vinh Dien river and reach the suction tanks of Cam Sa and Vinh Dien pumping stations.

To ensure irrigation water for agricultural production areas, especially summer-autumn rice areas, the Vu Gia - Thu Bon Irrigation Branch has reported to relevant units for monitoring and direction. At the same time, it proposed the Department of Agriculture and Environment and the People's Committee of Da Nang City to request the owners of hydropower reservoirs on the upper Vu Gia - Thu Bon River to operate and regulate the increased water discharge flow, maintaining a stable flow downstream.
