    NGỌC THÙY |

    Currently, on the To Lich River, there are still many sewers that are still discharging directly into the river without being connected to the general collection system.

    To Lich River is 14.6km long, flows through 6 districts: Ba Dinh, Cau Giay, Dong Da, Thanh Xuan, Hoang Mai, Thanh Tri and is the main drainage axis of Hanoi.

    Although over the past decades, Hanoi City has proposed many plans to revive this river, they have not been as effective as expected.

    According to Lao Dong, currently, To Lich River is heavily polluted, smells bad, and both banks are dirty and unsanitary.

    Along the riverside area (Quan Hoa - Hoang Quoc Viet section) there are many sluice gates that discharge directly into the riverbed.

    Regarding this issue, according to statistics from the Department of Construction, there are currently 119 sewers and most of them have been connected to the sewer system running along both banks of the river under the Yen Xa wastewater treatment plant project. However, there are 32 sewers still discharging into the river that have not been connected to the general collection system because they belong to another project (the section from Hoang Quoc Viet Street to Lang Ha intersection).
    So Xay dung dang len phuong an trinh thanh pho de dau noi nhung cong nay vao he thong gom ve nha may xu ly Yen Xa. Trong do, mot so cong se duoc bit lai de dan nuoc chay qua song Nhue.
    The Department of Construction is developing a plan to submit to the city to connect these sewers to the collection system at Yen Xa treatment plant. Some of these sewers will be blocked to divert water through the Nhue River.

    According to many experts, to deal with the pollution of the To Lich River, the most important thing is to treat the waste flowing into the river and maintain a minimum flow in the river system.

    Prof. Vu Trong Hong, former Deputy Minister of Water Resources, assessed that the wastewater discharges along the To Lich River have begun to be controlled and are no longer discharged directly into the river. Hanoi is collecting the above wastewater sources into pipes to lead to the Yen Xa wastewater treatment plant.

    Meanwhile, speaking to Lao Dong, Associate Professor Dr. Tran Duc Ha - former Director of the Institute for Water Supply and Environment Research (Vietnam Water Supply and Drainage Association) - said that bringing water from the Red River to rescue the To Lich River is necessary. The river must have a flow and measures to bring water from the Red River to replenish West Lake, thereby improving the water quality of the To Lich River are among the immediate tasks that need to be done. In addition, it is also necessary to create a flow and enhance the self-cleaning process in the river during the dry season by adding clean water.

    To revive this river, most recently, the Yen Xa wastewater treatment plant project (Thanh Tri) has begun a 6-month trial operation after 8 years of construction, with a capacity of 100,000 m3/day and night. The project aims to improve the living environment, natural ecosystem and sanitary conditions in the central urban areas of the To Lich river basin, the left bank of the Nhue river and the Lu river basin.
