Maccaferri uses Gabion baskets to solving the Selangor Water Crisis caused in part by erosion

Erosion control

Maccaferri Malaysia recently installed an Erosion Control Solution for Kelau Dam consisting primarily of Gabions

The Pahang-Selangor Raw Water Transfer Project is a RM 3.93 billion project funded by the Malaysian Federal Government and the Japan Bank for International Cooperation (JBIC).

The twin pipelines that transfer water from the Kelau River, Pahang to Langat River, Selangor; is the longest raw water transfer tunnel in South East Asia, and the seventh in the world. The project is expected to be fully operational in 2017.

When completed, it will have the capacity to channel 1.89 billion liters of water a day to consumers in Selangor, Kuala Lumpur, and Putrajaya up until 2025. The Kelau Dam is one of the major components of the Pahang-Selangor Raw Water Transfer Project as it is located directly in the catchment and pond area.

Its infrastructural development included a 33-meter-high and 4,600-meter long concrete and earth filled dam. Maccaferri’s products and solutions were explicitly specified for this project due to our proven quality and reliability on which clients have relied on over the years.

To elaborate further, the solution provided by Maccaferri primarily involved Gabions. Maccaferri gabion baskets are made from high-quality steel wire, which is heavily galvanized to provide long-term corrosion protection.
An additional protective polymeric coating is also applied for gabions that are to be used in more aggressive environments, or where a longer design life is required.

To reinforce the structure, all mesh panel edges are selvedged with a wire having a greater diameter.

For this particular project, Gabion was placed alongside the river and the pond or catchment areas to prevent erosion. Gabions measuring 1.0m and 0.5m in height provided a sturdy structure to the total area of protection, covering approximately 17,000 m3.
