Service Area Management towards Integrated Maintenance of Saguling Reservoir as the Raw Water in Bandung Metropolitan Area, Indonesia

摘要

Bandung Metropolitan Area (BMA) or the Great Bandung is one of the metropolitan areas that covers Bandung City, District Bandung, District West Bandung, Cimahi City, and some part of the District Sumedang in West Java Province, Indonesia. Over the past decades, BMA records an immense economic growth of over 8% per year. Currently, fulfilling the need of drinking water in Bandung City is overseen by Local Water Company (PDAM) of Bandung City with the capacity of serving 69.30% of the population. However, PDAM of District Bandung can only serve 30% (78,946) of its customers in Upper Citarum Watershed. When the plan for the potential usage of spring water source and the surface water in BMA is realized, it will produce 3400 L/seconds of available water. However, the available water would only be sufficient to meet the need of the population till 2015 only. Thus, it is required to find an alternative source of water by making use of Saguling Reservoir. The aim of this study is to determine the availability of the water in Saguling Reservoir in every repeat period of 5 dry years (R5) and every repeat period of 10 dry years (R10). The research also reveals the priority service area of Saguling Reservoir as the source of raw water.
