Evaluasi Jaringan Distribusi Air Minum PDAM Tirta Malem Unit Kabanjahe dengan Epanet 2.0

Abstract

Clean water as city infrastructure plays a role in supporting the development of the city. Modern and rural cities need a good clean water system, so as to meet the needs of their population growth. Based on the presentation of the number of house connections with 44.2% of the community has been served in the PDAM Tirta Malem service area in Karo Regency. The problem of PDAM Tirta Malem is where the distribution of PDAM water in Kabanjahe District is uneven. The production discharge from Lau Bengap itself is 50 l / d the location of the Lau Bengap Reservoir itself is in Manuk Mulia Village, in its service Lau Bengap serves 5,220 house connections in Kabanjahe District, the total population of Kabanjahe District has a population of 73,581 people, the water needs of PDAM Tirta Malem Kabanjahe District in a day is 3,393,000 liters / day. PDAM Tirtamalem's piping network in Kabanjahe District uses Polyvinly Chloride (PVC) pipes. The pipe meters used vary with sizes of 50 mm, 100 mm, 150 mm, 200 mm, 250 mm and 300 mm. The simulation results provide results in Kabanjahe District, there is negative pressure in several areas, especially on even roads and catepuls. To serve its own service area gravity has not been able to work optimally for water use at this time in the Lau Bentang spring service. So it takes the addition of pumps, the addition of suction pumps and the change of pipe diameter which serves to increase pressure in the network so that water distribution in Kabanjahe District can flow normally.
