ANALISIS KETERSEDIAAN DAN KEBUTUHAN AIR BAKU DISTRIK BONGGO KABUPATEN SARMI

Abstract

The development of an area will cause the demand for water to continue to increase along with the
population growth rate. The fulfillment of food needs and the activities of the population are always closely related
to the need for water. The demands are unavoidable but must be predicted and planned for optimal utilization.
The tendency that often occurs is the imbalance between water availability and water demand. To achieve a
balance between water demand and availability in the future, efforts are needed to assess the components of raw
water availability and demand as clean water sources.
The source of clean water for the people of Bonggo District, Sarmi Regency, comes from borehole pumps,
shallow wells (pumps), and rainwater. The analysis results on the need for domestic and non-domestic clean water
in the Bonggo District in 2023 show a total requirement of 210.38 liters/day or 0.0024 m3/second. The need for
clean water is expected to increase by 2043, with the total requirement for domestic and non-domestic clean water
reaching 285,820 liters/day or 0.0033 m3/second. The availability and need for clean water sourced from raw
water that can be utilized as clean water comes from pump bore wells as a suitable raw water source. In terms of
quantity, it is available 24 hours a day and throughout the year. The investigation results of the pump bore well
raw water source meet the clean water quality requirements according to Government Regulation No. 82 of 2001,
Level II. This is supported by groundwater, obtained through the analysis of geological conditions, land cover,
morphology, and river flow, which have a high to very high groundwater potential score, located in the northern
part of Bonggo District. Economically, in terms of quantity, rainwater can be used as clean water due to its sufficient
availability, with high rainfall (104,775 mm/year) and year-round service (continuity), and in terms of quality, the
results of rainwater quality tests meet the clean water standards according to quality standards.
