Hanoi Water Supply and Sewerage Company has proposed using the Red river’s water through a system of pumps to supplement West Lake and clean up the To Lich river.

Currently, building a sewage collection system along banks of Hanoi's polluted river is the last and the best option.

The project aims at facilitating transport and reducing accidents along Lang street which runs parallel to the To Lich river and at crossroads in the area.

The To Lich river’s landscape needs to be renovated by collecting all sewage for treatment, that ensures environmental standards before it is discharged back into the river.

Hanoi’s wastewater treatment site is a key and vital project as it would collect and purify sewage discharged by people in seven districts.
