Under the plan, approved recently by the municipal People’s Committee, the company will dredge some 57,400cu.m of mud from the lake and take measures to clear all waste and rubbish from the lake.
The work will be carried out from 11pm to 5am from Monday to Thursday and from 12pm to 5am from Friday to Sunday to avoid affecting other daily activities.
The plan is estimated to cost 30 billion VND (1.33 million USD) from the city’s budget.
During the cleaning process, the company will take measures to prevent noise and ensure labour safety and clean working areas.
The company will also work with scientists and experts to implement measures to protect all aquatic animals and plants in the lake during the cleaning process.
The lake is severely polluted and has lost the ability to revive itself, threatening living creatures in it, according to the company.
Covering some 12ha, Hoan Kiem Lake (also known as Returned Sword Lake) is located at the centre of the capital. Apart from its spiritual and cultural values, it is considered a scenic venue and a hub for some weekend relaxation, away from the chaos and bustle of the city.
