Hanoi (VNA)
- Japan will help Hanoi to improve its water quality through a project on non-chemical treatment for underground water.

The project signing ceremony was held in the capital city on February 4 with the participation of representatives from the Hanoi Water Limited Company (Hawaco), the Japan International Cooperation Agency (JICA) and relevant authorities.

The project is an initial effort in improving water quality by using Kemiresu, a fast processing, low cost, and environmentally friendly system to treat impurities in underground water which does not require the presence of chemical substances.

The Japanese-funded project has a total investment of 100 million Yen (851,000 USD) with an implementation duration of one and a half year starting in 2016.

Hawaco supplies 80 percent of tap-water for the city with 12 water filtration plants. However, water filter system degredation at all 12 units has hindered eliminating impurities in underground water such as iron, manganese and ammonia.

According to the Vietnam Water Supply and Sewerage Association (VWSA), a small-sized Kemiresu system will be initially applied at water-filter plants in Hanoi and southern Ho Chi Minh city.

The project will be trialed at the Hawaco’s Tuong Mai plant and is expected to provide locals with safe drinkable tap-water.-VNA
