Conservation of Underground Water with the Ecosystem Approach to the Development of the New Towns in Bogor, Tangerang, Bekasi (Botabek) Region

Abstract

The limited supply of clean water led to some residents in the city, as well as business and trade areas using underground water. Optimization of land used in the development of new towns and expanded impervious land surface, thus reducing infiltration capacity, resulting in an increased volume of runoff. The use of underground water and the reduced infiltration of rainwater resulted in a decrease in the underground water table. To maintain the underground water table and preventing land subsidence resulted from the use of underground water as raw material for clean water. The effort required is how doing underground water conservation. This paper discusses the development of new towns to assess the natural landscape as underground water conservation efforts on the development of the new town. The research method uses a quantitative approach to calculate the potential runoff using a soil conservation service, while to analyze the trend of changes in land cover using temporal spatial analysis, using descriptive analysis. The data used satellite imagery. The study found open green spaces, water bodies, and infrastructure in the form of green corridors can reduce runoff and maintain the underground water table.
