Thimphu residents could soon see relief from the city’s recurring water shortages. A major water transmission line in Thimphu is being realigned to protect the water supply from landslides and unstable slopes. The Nu 41 M worth project is expected to improve long-term water security for residents.
Thousands of people in Thimphu rely on the water source at Dodeyna every day.
And the water reservoir, nearly the size of a basketball court and about three metres high, forms a key part of the capital’s water distribution system.
But the main transmission line that carries water from this source has become increasingly vulnerable to landslides and unstable slopes.
To reduce the risks, Thimphu Thromde has started realignment works with climate-resilient measures designed to protect the infrastructure and improve emergency response.
“The realignment works are aimed at reducing the risks of pipe damage and water supply disruptions. The current water transmission line is also located on steep terrain, making repairs challenging, as all equipment has to be carried manually,” said Ugyen, Taba-Dechencholing Thuemi, Thimphu Thromde.
According to the Thromde, nearly 70 per cent of residents depend on this main transmission network.
The urgency of the project increased after a landslide near Dechencholing Bridge in October 2024 damaged parts of the area, raising concerns about the system’s stability.
“With the new realignment from Pangrizampa, equipment can be transported by vehicle because the pipes will now run closer to the road. This will help us respond quickly if pipes burst or the water supply is disrupted,” said Ugyen, Taba-Dechencholing Thuemi, Thimphu Thromde.
The project is covering a 2.5-kilometre stretch between Pangrizampa Bridge and the Taba slide area, where landslides and unstable slopes have posed increasing risks to the water transmission line.
Work on the project began about a week ago and is expected to be completed by August this year.
Once completed, the new alignment is expected to reduce service disruptions and strengthen the reliability of Thimphu’s water supply system for years to come.
