The work has returned beautiful scenery for Hoan Kiem Lake which is one of Hanoi`s symbolic places.
The water in Hoan Kiem Lake has been clean again and the lake has almost regained its original beauty to be worthy of the title "The Heart of the Capital City" thanks to the effort of the Hanoi authority, local media reported.

The Hanoi Drainage Company have set up a project to improve Hoan Kiem Lake’s environment with three main solutions including dredging the accumulated mud and waste at the lake’s bed, periodically feeding water to the lake and regulating the water level to create exchange of the lake’s water, using Redoxy - 3C inoculants to treat pollution when necessary.

Work on cleaning Hoan Kiem Lake water begun on December 1, 2017. Until February 7, 2018, 57,000m3 of sludge and residues in the lake’s bed was removed by C2 dredging technology and manually.
