Explanation of selection

The Metropolitan Waterworks Authority Of Samsen (MWA) was the first water supply service of Thailand granted by King Rama V who had a clear vision of the importance of good hygiene. Such waterworks have been vital services at that time. Especially, the Filtration House shows great structural technology. The project of Thai Waterworks Museum can be an example of adaptive reuse in Thailand. It can be suggested that setting the management teams will help the project sustain its values to the future.
