Design of a digitalized recharge system for groundwater sustainability in water exploitation areas

The transition of land use from open to closed areas has reduced infiltration spaces, causing a significant increase in surface rainwater runoff. Consequently, this has resulted in flooding during the rainy season and drought during the dry months, a phenomenon observed throughout Indonesia, especially in urban areas. Additionally, groundwater exploitation by drinking water companies, as witnessed in Sukabumi and other regions in Indonesia, is suspected to exacerbate the drought, causing widespread community concern over the past decades. Given these challenges, this research aims to develop a design for an infiltration well capable of harvesting rainwater and facilitating the seepage of household wastewater. This infiltration well water treatment design is equipped with sensors to detect the infiltration water discharge so that the infiltration water discharge can be known periodically. Based on measurements via sensors in infiltration wells, in each water exploitation area, the number of infiltration wells needed can be identified. It is hoped that this design can then be applied to the construction of housing complexes, as well as being the basis for stakeholders in determining the requirements for infiltration wells when changing open land to closed land.
