Aqua One Company chaired by Ms. Do Thi Kim Lien is the largest shareholder with 51% stake.

Last September, Aqua One and WHAUP signed a strategic cooperation agreement on the development of the Duong river surface water plant in the next five years.

SDWTP has a capacity of 54.75 million cubic metres per year and plans to increase it to 109.5 million cu m per year.

The new capacity is expected for commercial operation by 2019.

Wisate Chungwatana, chief executive of WHAUP, said the utility business in Vietnam has significant growth because of the country's good economic sentiment and growing urbanisation.

The General Statistics Office of Vietnam reports Hanoi's population is 7.8 million in 2018 and is expected to reach 9 million by 2025.

Hanoi's clean water supply capacity is just over 401.5 million cu m per year, including SDWTP.

Meanwhile, average clean water demand in Hanoi is 547.5 million cu m per year.
