Artificial Recharge for Sustainable Groundwater Management Plan in Yogyakarta

Abstract

<strong>Aim: </strong>This study investigates the development of a sustainable groundwater management strategy in Yogyakarta province through groundwater recharge technologies. This study also compares technologies used in the province and the one already implemented in Perth due to its similar nature in site geology and hydrogeology. <strong>Methodology and Results: </strong>Primary and secondary data were collected and analyzed. Water depth and hydraulic conductivity data were analyzed using permeameter and GIS program. GIS image analysis of water depth and hydraulic conductivity suggested that the placement of potential aquifer recharge sites would be best suited in the north-east part of the province, slightly outside the study area, to provide water for all. Two recharge schemes of an infiltration basin and an injection well with storm water detention tank were proposed. The injection well was decided upon, despite its higher cost, due to the impermeability of soils in Yogyakarta and possible water seepage to the environment. Similar to Perth’s Hartfield park scheme, an injection well would directly bypass these soil layers to recharge the aquifers with rainwater and storm water. Hartfield Park injects 4400 kL of water/year. <strong>Conclusion, significance and impact study: </strong>The findings of this study indicate aquifer recharge is a possible solution to overcome Yogyakarta’s high abstraction. Further studies recommend that injection well trials are further developed in terms of location, depth and sizing.

A GIS-based analysis of groundwater manganese and nitrate concentration for sustainable water supply

“…The increase in population has resulted in high groundwater abstraction, but it did not jeopardize the groundwater balance and the groundwater level of Yogyakarta City [6]. On the other hand, recent papers on groundwater quality in Yogyakarta Province have shown a few issues regarding the pollution risk potential in Yogyakarta City [7], and groundwater management in Yogyakarta Province [8]. A study also identified the temporal variation of groundwater quality and nitrate and manganese elevated concentration in the Sleman District of Yogyakarta Province [9].…”

Evaluation of Trends for Iron and Manganese Concentrations in Shallow Groundwater, Jakarta City

“…32 [4] has set quality standards for groundwater quality for sanitation hygiene needs that must include physical, biological, and chemical parameters. Knowing the distribution of groundwater quality in urban cities is an informative tool in the form of a geographic information system (GIS) as an effective way to represent and analyze spatial data on water resources [5,6]. So that the mapping results in the form of a spatial map will describe the water quality categories found in the entire study area [7].…”
