HA NOI (VNS) — Substandard pipelines and construction, along with construction work on the Thang Long Boulevard are the three main reasons for the broken water pipeline between Da River and Ha Noi.
This was the official conclusion of the Ministry of Construction (MoC) after checks, tests and analysis carried out by them.
The pipe broke on Tuesday, leaving around 70,000 households in the capital's Ha Dong, Thanh Xuan, Hoang Mai, Tu Liem, Dong Da and Cau Giay districts without clean water.
This is the seventh time the pipeline has broken since it began operations in 1997.
The main reason for the broken pipe was its poor quality, according to the MoC. Some parts of the pipe system came off and the officials did not adhere to some mechanical norms, leading to the decrease of the pipe's pressure resistance.
Construction work on the pipe system also did not follow technological requirements and standards. Moreover, the Thang Long Boulevard's construction after the pipe system was already completed and the weight of vehicles passing the boulevard were the indirect reasons for the breakage.
The MoC asked the Vinaconex Clean Water JSC, which was the investor of the pipe system, to check the overall system's pressure and output to discover unusual problems and maintain the stable pressure in the system.
The company should set up measures quickly in case of any problems to prevent loss of clean water and ensure the system protects the corridor.
The ministry also asked the company to complete the necessary procedure to install a clean water pipeline in the second period to meet the demand of users and for the development of the city.
Analysing the responsibility of relevant bodies, the MoC said that the design agency lacked experience in choosing the pipeline and did not reveal the necessary technological norms during the construction.
The pipeline manufacturer did not choose the right process and did not conduct tests to prove the pipeline's durability.
The construction agency must take the responsibility for leaving freestone and concrete in the sand that covered the pipeline.
The construction supervising agency did not undertake close checks and inspections leading to shortcomings in the construction process.
The project management committee must take the responsibility for poor quality management. — VNS
