SUSTAINABILITY APPROACHES ADOPTED FOR STORMWATER AND DEPOSIT PONDS CONSTRUCTION OF ANKENG MRT SYSTEM IN NEW TAIPEI CITY

Abstract

The Ankeng Light Rail MRT System (ALRMS) is one of the most critical transportation project, which is located in New Taipei City, Taiwan. The ALRMS is under construction and is expected to be finished and serve to transportation in 2022. One of the most significant environmental achievements is the adoption of the sustainable method for the construction of the basin, which is for temporary storage of the silts/debris. Several methods were evaluated in this project. The engineers determine to use the gabion structure to replace the traditional RC structure for the Storm water and Deposit Ponds (SDPs) construction. The materials of the gabion structure are taken from nature. It could significantly reduce the use of cement, rebar, formworks, and other materials which are produced by the human. Not only the carbon emission can be massively reduced, but also the construction duration is drastically shortened. Furthermore, the ecological conservation issue is also taken care in the construction of the SDPs. This experience could be served as a valuable reference for the sustainability development of other similar infrastructure projects.
