Ha Noi: Installing 38 cluster of aquatic rafts to improve To Lich river’s water quality
To Lich river has total length of 13, 3 km and 20 km2 of drainage flow; it located in Hoan Kiem district, Ba Dinh, Dong Da, Thanh Xuan, Thanh Tri. Water flow can reach to 150.000 m3/ day. Most of urban waste water is untreated so water of river becomes more and more polluted. In an attempt to improve water quality, Ha Noi Drainage One Member limited Company set up 38 cluster of aquatic crafts in To Lich river.


Installing process are implementing on section from Hoang Quoc Viet street to Cau Moi bridge (So Crossroads in Ha Noi), with total length over 6 km. The frame crafts are made from floating materials, each cluster is separated 30 cm away. Aquatic plants play role as factors helping clean due to its root and body that has filter functions, converts polluted compounds into biomass, and releases oxygen to the water.

Aquatic rafts are low cost tools which have life span up to 4 years. Therefore, this project seems an appropriate and friendly solution.
