ANALISIS JARINGAN PIPA DISTRIBUSI AIR BERSIH PADA DAERAH PEMUKIMAN MENGGUNAKAN PROGRAM WATERCAD

Abstract

ABSTRACT
This research is aimed to show the ability of tube tissue system distributes
clean water in Balikpapan City recently. The use of waterCAD software is one of
the alternative programs to drive an element tube exchange to get a better
clean water distribution tissue.
The data of the research are city population, topography photograph,
skeletonize-model map and its equipment. The data then were used for the input
of waterCAD software. According to the output of the program, it shows that it
should be a change of tube elements to gain pressure standard 150-300 kPa
using scenario management facility.
The result analysis using waterCAD software shows that the capacity of
clean water distribution pipe at this time have not been able to suffice the clean
water demand, in this condition, the water flow has average pressure -29.735,05
kPa which is not appropriate with pressure standard. The alternative program to
solve this matter is the change of tube diameter to 400, 500, and 600 mm and
tube material from Galvanized Iron and Steel. The pressure after the change is
174,5 kPa. The computation dispute between waterCAD software and analytic
computation is 0,71% for flow debit and 2,27% for pressure at node. The difference
shows that the waterCAD software has been thoroughly tested.
