Analisis Kebutuhan dan Ketersediaan Air Bersih Daerah Pengembangan Kota di Kabupaten Konawe Selatan

Abstrak

Climate change has become a global concern, particularly its impact on water availability, which is either increasingly scarce or results in excess water discharge at other times. This necessitates sustainable water management policies. This study aims to analyze the needs and availability of clean water in the urban development area of Konawe Selatan Regency, particularly in the Palangga Subdistrict.The study employs a mixed-method approach, combining qualitative and quantitative methods. Data analysis is carried out using descriptive analysis. The findings reveal the following: The water demand in Palangga Subdistrict over the next 20 years (2024–2044) includes both domestic and non-domestic water needs, which are projected to increase along with population growth. By 2044, domestic water demand is estimated to reach 11.05 m³/day, while non-domestic demand is expected to be 3.87 m³/day, resulting in a total demand of 14.92 m³/day.The water availability in Palangga District is sufficient to meet both domestic and non-domestic needs. Alakaya Village has the highest water availability, amounting to 159,877,440 m³, while Kapu Jaya Village has the lowest water availability, amounting to 24,848,941 m³.The water balance in Palangga Subdistrict is projected to remain stable until 2044, considering groundwater as the main source. Adequate groundwater availability is supported by potential groundwater sources, but its usage must be monitored to prevent overexploitation. A decline in groundwater availability could occur due to environmental changes.
