[Explanation] On October 26th, the "Spirit of the Times Brilliant Xiangjiang River" is a big country to build a major livelihood project in Hong Kong. The reporter from China News Agency followed the media group to visit the Hong Kong Tseung Kwan O Desalination Plant Phase I, which is under construction. Here is a mountain By the sea, the scenery is pleasant, and it is also a destination for local travel, photography and sports enthusiasts in Hong Kong.
[Explanation] Zhang Ming, Assistant President of China State Construction International Corporation, said in an exclusive interview with a reporter from China News Agency that the first phase of the Hong Kong Tseung Kwan O Desalination Plant is located in Tseung Kwan O Area 137. The contract value of the project is 9.018 billion Hong Kong dollars. The largest livelihood project undertaken by the integrated model of "design, construction, and operation", and the design of the project also has many highlights.

This project has three major features. The first feature is the largest single livelihood project in the history of the Water Supplies Department of the Hong Kong (SAR) Government.
The second feature is that it uses the world's more advanced "reverse osmosis" technology.
The third point is our construction difficulty. Two tunnels on the seabed are used for water intake and future drainage. This is some of our construction difficulties.
[Commentary] In the morning of the same day, the reporter arrived at the construction site with the media delegation.
During the visit, the reporter found that the water near the water intake point was crystal clear and the water depth was about 7 meters.
Zhang Ming introduced that relevant personnel had made an assessment before the project that the water quality of the sea area was good, and the project had little impact on the surrounding marine environment.

Our entire water pipeline on the sea floor is 170 meters long, and there are 34 pairs of divergent outlets for salt water. This outlet is perpendicular to the direction of the ocean current, so the ocean current will take away the salt water immediately.
Therefore, we will try our best to make it dilute to its original natural state as soon as possible in the direction of the vertical ocean current.
[Explanation] Zhang Ming told reporters that the first phase of the Hong Kong Tseung Kwan O Desalination Plant won the bid on November 12, 2019, with a construction period of 39 months and an operation period of 15 years.
At the beginning of 2020, in the face of the sudden new crown pneumonia epidemic, the construction of the project is facing severe challenges. In order to ensure that the progress of the project is under control, the model of "prefabrication" in the Greater Bay Area and "installation" in Hong Kong was adopted.
[Concurrent] Zhang Ming, Assistant President of China State Construction International Group
We include concrete and bricks for temporary roads, as well as some concrete construction for permanent factory buildings in the future. We try our best to choose “off-site prefabrication” in the vicinity of our construction site in the Greater Bay Area.
Although this project started with the epidemic, our current progress is under control and reached the original plan because a large number of "off-site prefabrication" processes have been adopted. In the previous period, some of the "off-site prefabrication" were not used in the early stage of construction. "Some things in the concept of ", we have gradually optimized in the process, and gradually adopted the "off-site prefabrication" method.
[Explanation] Zhang Ming said that the first phase of the Hong Kong Tseung Kwan O desalination plant is currently progressing well, and it is believed that it can be completed in mid-2023 as scheduled and will be put into use thereafter.
Upon completion, the first phase of Hong Kong’s Tseung Kwan O Desalination Plant will be the first reverse osmosis desalination plant to be put into use in Hong Kong, with a daily production of 135,000 cubic meters of fresh water, accounting for 5% of Hong Kong’s total daily fresh water demand.
