Revitalization of Beihai river turns area clean and green

Over the past two years, about 30 kilometers of pipelines were laid to intercept sewage discharged to the river and channel it to treatment facilities. 540,000 cubic meters of sludge were removed from the waterways, as well as obstacles that blocked the river flow.

The river has also been replenished with reclaimed water as a way to improve water quality and help self-cleaning. The large pond areas have been retained, but are no longer used to keep shrimp. They have been planted with different kinds of aquatic plants to help purify the waters and offer habitats for water creatures.

On the banks, more than 30 kinds of plants have been cultivated in different sections to recover vegetation and filter the rainwater. Due to sea tides, the water is salty in the middle and downstream, so mangrove, alkaline grass and other saline plants have been planted there.
