Abstract

Life is not possible without water, so we need to supply enough water to sustain well in life. Insufficiency of clean water is a major problem for urban communities today. For this reason, it is necessary to estimate the required amount of water. Thisissue will be slowly reduced by planning clean water supply in cities. This study was conducted as a case study in Palopo City, South Sulawesi. The population data is used as a reference when calculating domestic water requirements. The main objective of this study is to measure the clean water needs of community in Palopo City over a forecast period of up to 20 years. As a result of this study, the city of Palopo's water demand in 2027 is 29,510.37 m3/person/day for domestic use and 10,773.95 m3 for non-domestic use including water loss due hydrants and leaks. 31,685.72 m3/person/day for households in 2032, 13,493.76 m3/person/day for ordinary households, 33,744.08 m3/person/day for ordinary households in 2037, 13,884.27 m3/person/day for ordinary households, 35,741.65 m3/person/day for households and 14,183.00 m3/person/day for non-households. The city of Palopo's water production from multiple sources is 65,664.00 m3/day. At the end, it can be concluded that water needs in Palopo City will be quantitatively met by 2042.
