Vietnam addresses wastewater management in Quang Ninh and Ho Chi Minh City

In Quang Ninh province, the coal industry is increasing the reuse of resources to improve economic efficiency and reduce environmental impact. Companies like Than Cao Son - TKV are repurposing treated mine wastewater for dust suppression on transport routes. On average, the company uses 4,500 cubic meters of water daily for these activities, with approximately 3,000 cubic meters sourced from treated mine wastewater. The TKV Environment Company currently manages 39 wastewater treatment stations in Quang Ninh, processing between 135 and 140 million cubic meters of water annually.

Meanwhile, Ho Chi Minh City faces significant pressure to manage over 3 million cubic meters of domestic wastewater generated daily. Currently, only about 19.5 percent of urban wastewater is collected and treated, leading to pollution in rivers and canals. While industrial and medical wastewater treatment rates have reached 100 percent, the city struggles with a lack of synchronized collection networks and slow progress in building treatment plants due to financial and land constraints. The city aims to collect 80 percent of urban wastewater and achieve a treatment rate of over 70 percent by 2030.
