WSUD Techniques for Urban Development with Focus on Saltwater Intrusion Problem, A Case Study of Kedonganan Village - Bali

Abstract

Water is one of the most important resources in human’s life, and groundwater known as the largest freshwater source in the world. Along the development of the cities and population growth, the demand for water supply is also increasing. With the increasing of the freshwater needs, groundwater is also widely used for human’s daily activities. However, the irresponsible use and exploration of groundwater also certainly generate many problems, one of those is saltwater intrusion. Many coastal areas in Indonesia are starting to face saltwater intrusion problem which cause groundwater is no longer be used properly by the community. Therefore, the problem of saltwater intrusion needs to be addressed. This research aims to see the WSUD techniques which can be applied to prevent saltwater intrusion in coastal areas with Kedonganan Village as a case study. The research methodology used is descriptive qualitative method. For the result of this research, those are some WSUD techniques which can be applied in urban development to prevent saltwater intrusion occurs: rainwater tank, downpipe diverters, biofilters, infiltration basins & trenches, soakwells, swales & buffer strips, and pervious paving which have focus on accelerate infiltration into the aquifer.
