PLANNING OF CLEAN WATER DISTRIBUTION NETWORK IN OHOI KELANIT KEI KECIL DISTRICT OF SOUTHEAST MALUKU REGENCY

Abstract

Ohoi Kelanit is a village in Kei Kecil District of Southeast Maluku Regency, with an area of 13.37 km2. Based on population data in Ohoi Kelanit in 2020, the population of Ohoi Kelanit is 982 people with the number of KK which is 208 KK. Judging from the conditions that occur in Ohoi Kelanit, where there are no clean water facilities available and for the use of clean water residents still use well water or buy water. Based on existing conditions that there is already an IPA with a capacity of 100 liters / second owned by PDAM Maluku Tenggara, but the use of clean water from this IPA is only focused on urban areas (Langgur) while in Ohoi Kelanit has not been served by PDAM. Therefore, from the capacity of 100 liters / second this will be taken for the planning of the clean water distribution network in Ohoi Kelanit. From the results of the analysis obtained the need for clean water in Ohoi Kelanit for a period of 10 years is 19,087 liters/second with a reservoir capacity of 42 m³. Based on the epanet 2.0 program simulation, the pipe used in the planning is a GIP pipe with a pipe dimension of 3" (P = 474,07 m), diameter 2" (P = 178,78 m), diameter 1 ½" (P = 572,79 m), diameter 1 ¼" (P = 1114,85 m), diameter 1" (P = 559,43 m). Velocity of 0,32 – 0,79 meters/second and pressure in the pipe of 5,45 – 25,67 meters.
