Architectural typology of water infrastructure: Case study of green open space and heritage site of perigi pekasem in Bangka Belitung

Indonesia as the top 10 countries in extensive groundwater extraction, has fallen behind in providing basic water services infrastructure. While the water utility in Indonesia only provides 35.15% coverage nationally. As case, Bangka Belitung as the lowest province in water management provision with only 17.26% coverage faces tremendous sustainable issues because of its massive exploitation of water usage for domestic, industrial, and especially tin mining activities. Indeed, in spite of fact that water infrastructure is always an essential part of the history of the built environment such as the Roman aqueduct, India’s Stepwell, and Nasqa Puquio. In Indonesia has shown that the number of architectural studies focused on improving the water services is small. In response to Sustainable Development Goals number 6 on clean water and sanitation, this study aims to contribute and mainstream the discussion of green infrastructure in the architecture discourse by analyzing and identifying its typology and design elements using the heritage-built environment of Bangka Belitung’s perigi as the case study. The result of identified design elements and typology on the cultural landscape can further be used to enrich the architecture discussion and design vocabulary on Indonesian cities’ urban fabric and contribute to the expected achievement progress on sustainable development goals.
