One Very High Impact Project of tunelling raw water from Pahang to Selangor today sees its ground breaking ceremony by His Majesty Sultan of Pahang.
It, when completed, will tunnel about 1,890 milllion litres of raw water a day from Semantan River to Selangor for fulfilling water needs of people in Klang Valley, Kuala Lumpur and Putrajaya.
It will also be the biggest and longest water chanelling tunnel in South East asia and the sixth largest in the world.
The tunnel will be 44.6 km long and 5.2 m diameter and will pass through Lentang Forest reserve, Bentong district and Hulu Langat Forest reserve. It will traverse the Titiwangsa range and pass through the bottom of several granite-bottomed rivers such as Congkak river, Predak river, Semungkis river and Gahal river in Selangor.
The regulating dam, Kelau dam will cover an area of 331 sq km.
This project will be the best to satisfy the water need of Selangor, Klang valley, and Putrajaya up to year 2025. It is made up of two components, the water tunnelling costing RM3.9 billion and water treatment in Langat costing around RM4.13 billion.
Talking to the DOE Director during lunch, he told me that this is the best from environemental point of view as water is in the pipe and no river is forced to change its course in the process.
The raw water will be sold at 10 sen per cubic metre and this rate will be reviewed every five years.
With the completion of this project, which will be in 2014, water woes in Klang valley and Putrajaya will be solved.
