| Summary: | West Lombok Regency is part of the West Nusa Tenggara Province (NTB) with topographic conditions at altitudes between 0-100 meters above sea level and slope levels in the range of 0-10%. PDAM Giri Menang is a clean water distribution business entity in West Lombok Regency with three service areas, namely the services are Mataram City, the southern and the northen. Northern service area include Gunungsari and Batulayar Districts which have reached a service level of 54.8% in 2019. Northern service have problems in terms of quantity and continuity at several service areas. With the "10 Million Connections for NTB" program to reach 100% of NTB residents served clean water, clean water distribution network optimization planning will be carried out for northern services. This influences the need for clean water that must be provided with service improvement plans due to population growth and public and social facilities in the future. This optimization plan will be designed for the next 20 years by dividing it into two planning periods, namely 1st period in 2029 and 2st in 2039. The northern service water distribution network optimization will be carried out by build a new distribution network from the Kalimeninting Dam water source that will also discharge injection towards the existing network distribution with a total planned capacity of 200-250 liters/second. Service levels will increase for periods I and II respectively to 88.15% and 96.3%. There are 3 optimization alternatives, namely using a branch system, a combination system, and a looping system. All alternatives were analyzed by using EPANET 2.0 hydraulic modeling. After obtaining the results of hydraulic, investment, and operational analysis for each alternative, the selection of the best alternative is done using the Simple Additive Weighting (SAW) method. From that method, alternative 2 is chosen as an alternative with a combination system distribution network. |
