Design of Clean Water Pipes in Bangga Village, South Dolo District, Sigi Regency

Abstract

This study is to provide an overview of the design of clean water pipelines in Bangga Village, South Dolo District, Sigi Regency. The limitation in this design is to analyze the availability of water/discharge mainstay of the Bangga River using the F.J Mock method and calculate the need for clean water in Bangga Village according to the estimated population for the next 27 years. The design method is carried out using meteorological data collection methods, data on population density, topographic data, and rainfall data, then calculates the need for clean water and is compared with the reliable discharge. The result is obtained a minimum mainstay of the Bangga River discharge (Qand 0.282 m3 / sec) to meet the needs of clean water in the service area until 2040 required a water debit of (6,295 ltr / sec). From the water requirements, 2 (two) design methods were designed which included 1 (one) clean water pipeline design and 2 (two) clean water pipeline design. From the design results obtained a maximum pressure of 4.2662 kg / cm2 which occurs at the node / pipe connection P.15 this does not exceed the maximum allowable limit of 10 kg / cm2, while the maximum speed obtained at 1.1688 m / sec which occur at vertices P, 6 and P. 12 this does not exceed the maximum limit of 3 m / sec. For the number of pipe requirements needed in this design are 1747 sticks, where for Ø 8 "17 sticks, Ø 6" 259 sticks, Ø 4 "108 sticks, Ø 3" 760 sticks, Ø 1 "565 sticks, Ø ½ "38 sticks.
