PERENCANAAN JARINGAN PERPIPAAN AIR MINUM MENGGUNAKAN APLIKASI WATERCAD V8-I

<p align="center"><strong>Abstrak</strong></p><p class="11daftarpustaka"> </p><p class="11daftarpustaka">Pelayanan kebutuhan air di wilayah IKK Bukit Oregon kurang memadai diduga jaringan pipa menjadi pokok masalahnya sehingga berdasar hal tersebut maka diperlukan evaluasi jaringan perpipaan air minum dan design dibuat dengan menggunakan software Aplikasi Watercad V8-I dan ingin diketahui seberapa besar kebutuhan debit pada proyeksi tahun 2030 termasuk kapasitas pompa dan jenis pipa transmisinya. Hasil pengamatan secara langsung di wilayah studi pada pelayanan terdapat permasalahan yang terjadi pada pipa transmisi, yaitu pipa dari intake (sumber air baku utama) menuju ke Instalasi Pengolahan Air (IPA) yang akan di distribusikan ke masyarakat. Permasalahan yang terjadi adalah pipa induk tersebut mengalami kebocoran akibat umur teknis pipa yang sudah tua. Meningkatnya jumlah penduduk sama halnya semakin meningkatnya pemenuhan akan kebutuhan air bersih. Permasalahan tersebut harus ditanggulangi dengan pergantian pipa dengan jenis dan diameter yang tepat serta kapasitas pompa yang sesuai hasil menggunakan software Watercad V8-i. Dari hasil perhitungan analisa pertumbuhan penduduk pada tahun 2030 dengan jumlah pelanggan 96.770 jiwa kebutuhan air mencapai 102,476 liter/detik. Sistem transmisi menggunakan sistem pompa dengan kapasitas terpasang 90 liter/detik. Jenis pipa yang dipakai untuk pipa transmisi menggunakan pipa HDPE dengan diameter 350 mm.</p><p class="11daftarpustaka"> </p><p class="11daftarpustaka">Kata kunci: evaluasi, <em>air bersih,</em><em> </em><em>perpipaan, pompa, Watercad V8-i </em><em></em></p><p><em> </em></p><p align="center"><strong> </strong></p><p align="center"><strong>Abstract</strong></p><p class="11daftarpustaka"> </p><p class="11daftarpustaka">The service for water needs in the IKK Bukit Oregon area is inadequate, it is suspected that the pipeline network is the main problem, so based on this, it is necessary to evaluate the drinking water piping network and the design is made using the Watercad V8-I application software and wants to know how much the demand for discharge in the 2030 projection includes pump capacity and type of transmission pipe. The results of direct observations in the study area on the service there are problems that occur in the transmission pipe, namely the pipe from the intake (main raw water source) to the Water Treatment Plant (IPA) which will be distributed to the community. The problem that occurs is that the main pipe has a leak due to the technical age of the pipe which is old. The increasing population is the same as the increasing fulfillment of clean water needs. These problems must be overcome by changing the pipe with the right type and diameter and the pump capacity according to the results using the Watercad V8-i software. From the calculation results of population growth analysis in 2030 with the number of customers 96,770 people, water needs reach 102,476 liters/second. The transmission system uses a pump system with an installed capacity of 90 liters/second. The type of pipe used for the transmission pipe uses HDPE pipe with a diameter of 350 mm.</p><p class="11daftarpustaka"> </p><p class="11daftarpustaka">Keywords: evaluation, clean water, piping, pump, Watercad V8-i</p><em></em><em> </em><em></em><em></em>

Water Carrying Ships in the Adriatic Region - Zadar Region Analysis

In this paper the main objective was to analyse water distribution market on Adriatic islands, mainly those without any water piping infrastructure. Those islands are mostly supplied by water carrying ships. The used methodology consisted of analysing, in last four years, the number of water deliveries and amount of precipitation in the research area. The analysis showed that the most critical situation occurs from June to September, when the number of residents grows and the amount of precipitation lowers. In order to avoid critical situations, like water reductions and draughts, important factors are pointed out which could lead to such situations and with proper precautions action can be avoided.
