Kanchanaburi’s 5 districts are set to benefit from a water diversion tunnel project that goals to alleviate drought issues. The project, which is valued at 12 billion baht (US$335,746,080), seeks to switch 378 million cubic metres of water from the Srinagarind Dam, the most important dam within the western area, to an space of 200,000 rai within the Huay Krachao, Lao Khwan, Bo Phloi, Nong Prue and Phanom Thuan districts of Kanchanaburi.

The Workplace of the Nationwide Water Assets (ONWR) accomplished the feasibility examine of the project throughout 5 districts in April 2021, in accordance to the project’s advisory crew consultant, Chaitas Imsamranrat. The tunnel, with its size of 20.5 kilometres and width of 4.2 metres, is deliberate to be executed in 4 phases.

The primary part includes directing water beneath a mountain at a mean depth of 500 metres to the Lam E Su reservoir at a price of 1.03 million cubic metres per day. This part, which additionally consists of the development of water-receiving and discharging buildings, is anticipated to price 4.28 billion baht (US$ 119,749,435).

Following this, a brand new water transportation system can be put in to channel water to a clarifier web site, a project that requires a price range of three.12 billion baht (US$87,293,980). The subsequent stage includes constructing a Lumrang clarifier web site, which is estimated to price 3 billion baht (US$83,936,520).

Lastly, an extra water transport system can be constructed to launch water right into a main concrete canal and its 42 sub-routes for public use. The price range for this stage is 3.99 billion baht (US$111,635,571).

Regardless of the project’s potential advantages, issues have been raised relating to its environmental impression, significantly the primary part, which is situated within the Salakpra Wildlife Sanctuary.

Nonetheless, Chaitas has supplied assurances of the project’s environmental security, highlighting that the project’s excavation course of will utilise a tunnel boring machine (TBM). The TBM is deemed probably the most environment friendly methodology for lengthy tunnels, providing increased productiveness and a safer work setting. It’s designed to excavate the doorway and the top of the tunnel concurrently, either side stretching roughly 10 kilometres, thereby minimising noise air pollution and different opposed impacts.

The drilling and blasting course of can be applied across the tunnel entrance to put together for the TBM on the principle tunnel. Every blast can create an area of 4 to six metres per day, and it could take about three months to attain 50 metres.

The project additionally has the help of Sakda Wichiansilp, Pheu Thai MP for Kanchanaburi and chairman of a Home committee finding out drought options to the El Niño climate phenomenon. He has referred to as on authorities companies to expedite the development course of and enhance consciousness of the project’s significance in mitigating drought points amongst locals.
