HA NOI (VNS) — Construction work for the second phase of the Da River water pipeline began yesterday in Ha Noi in the hope to better meet the local residents' need for clean water after several breakdowns of the old pipeline occurred.
Under the second phase, a new 46km second pipeline will be built to support the first one built in the first phase of the project in 2008 in case of any trouble.
In the initial stage, a new 21km pipeline will be built across the Day River (on the land of Quoc Oai and Hoai Duc districts), running parallel to the current one from National Highway 21 to Belt Road 3. It is expected to finish in May 2016.
The remaining part of the new pipeline and a new water treatment plant will be built and is expected to be operational in 2019.
The construction project was invested by Vinaconex water supply joint stock company (Viwasupco) with a capital of VND4.9 trillion ($218 million).
Once the second phase of the project is completed, the water supply capacity of the pipeline will rise from 300,000cu.m to 600,000cu.m per day.
It is expected to meet the local residents' need for clean water in urban centres of Son Tay, Hoa Lac, Xuan Mai, Mieu Mon, Ha Dong and Ha Noi.
The Viet Nam Construction and Import-Export Corporation (Vinaconex), the corporation in charge of the first pipe, was chosen to build the second one. But instead of using the same material as the first pipe, fiberglass, Vinaconex will use cast iron.
"Though cast iron pipe will be more expensive, its quality is higher and construction time is shorter, which will help make the pipe usable sooner," Nguyen Van Ton, Viwasupco's general director said.
"We will continue repairing the first pipeline to ensure that both lines function well and supply enough water for the residents."
In late 2008, the Vinaconex spent VND1.5 trillion ($66.7 million) on the old pipeline, which began delivering clean water from the Da River Water Factory in the neighbouring province of Hoa Binh to families in six Ha Noi districts.
The old pipeline, which was in its first phase, runs for 47km and has the capacity to supply 300,000cu.m of water per day.
Over the past four years, the pipeline transporting clean water from the Da River to Ha Noi broke or leaked 15 times.
Breakdowns have occurred more often this year. The latest incident took place on September 26, when part of the pipeline in Thach That District broke at 3am, causing a water shortage for 70,000 households in the city.
The water shortage forced hospitals in Ha Noi to delay non-emergency surgeries and created hardships for hundreds of patients in hospitals. — VNS
