Analisis Dan Rencana Pengembangan Jaringan Distribusi Air Bersih Unit Pelayanan Cabang Timur Pdam Kabupaten Klaten

Perencanaan ini dilakukan pembagian blok pelayanan menjadi 26 blok dan 5 tapping. Setelah itu dilakukan analisis kondisi eksiting. Hasil analisis kondisi eksisting menunjukkan kondisi hidrolika perpipaan kecuali kecepatan masih memenuhi kriteria, yaitu tekanan antara (15,43-59,99) m, kecepatan (0-0,91) m/detik, unit headloss (0-3,51) m/km. Kemudian dilakukan pengembangan jaringan yang dibagi menjadi 2 tahap, dimana tahap 1 meningkatkan persen pelayanan, sedangkan tahap 2 menambah ii daerah pelayanan baru. Blok pelayanan setelah pengembangan menjadi 29 blok dan 5 titik tapping. Kemudian analisis rencana pengembangan dilakukan dan menunjukkan bahwa kondisi hidrolika pipa untuk tekanan di jaringan distribusi IKK Cawas bernilai negatif. Hal ini dikarenakan unit headloss yang terjadi pada pipa dari reservoir menuju titik tapping pertama IKK Cawas sebesar 5,78 m/km dengan panjang pipa 14,35 km sehingga headloss sebesar 82,94 m menyebabkan tekanan menjadi -2,89 m. Permasalahan ini dapat diatasi dengan paralel pipa diameter 200 mm sepanjang 9 km. Paralel pipa tersebut mengakibatkan tekanan pada titik tapping pertama IKK Cawas menjadi 34,65 m dan titik tapping terjauh (blok 19) sebesar 16,34 m. Hasil analisis hidrolika, seperti unit headloss berada pada rentang (0-5,78) m/km, namun kecepatan masih ada yang di bawah 0,3 m/detik. Rencana anggaran biaya (RAB) yang dibutuhkan untuk melakukan pengembangan jaringan sebesar Rp 2.470.153,051.71. ============================================================= Service Unit in East Branch of Regional Water Utility Company (PDAM) Kabupaten Klaten is divided into three service units in the Capital Regency (IKK). It has a low service level in 2015 such as 17,6% in Ceper IKK Unit; 2,43% in IKK Pedan unit; and 31,26% in Cawas IKK unit, thus increasing the service level should be done. This is supported by the addition of production discharge of 50 liters/sec. In addition, the network distribution service block has not been established so it is difficult to control the water loss. In this study, the service block distribution is done, then analyzing the existing condition and plan the development of distribution networks using EPANET 2.0. The result is used as the basis of distribution network development plan. The increasing of service level is done based on customer growth trends in East Service Unit. In this study, the service block distribution is divided into 26 blocks and 5 tapping followed by analyzing the existing condition. The result indicate conditions of hydraulics piping; the pressure (15,43 to 59,99) m, speed (0 to 0,91) m/sec, headloss unit (0 to 3,51) m/km. The network development divided into 2 phases, where phases 1 is increasing the service, and phase 2 is adding new service areas. The development plan analysis after developing into 29 blocks and 5 tapping points shows that the conditions for pressure pipe hydraulics in the distribution network of Cawas IKK Unit is negative. This is because the headloss occurring in the pipe from the reservoir to the point of first tapping Cawas IKK Unit is 5,78 m/km to 14,35 km long pipeline so headloss of 82,94 m cause the pressure becomes -2,89 m. This problem can be solved with a iv parallel pipe diameter of 200 mm along the 9 km. The parallel pipes cause pressure on the first tapping point IKK Cawas be 34,65 m and the furthest tapping point (block 19) 16,34 m. The results of the analysis of hydraulics, such head loss units that are in range (0 to 5,78) m/km, but the speed is still there below 0,3 m/sec. Budget Plan (RAB) that is needed to carry out the development of networks is Rp 2.470.153,051.71
