pipa tegak air hujan menggunakan pipa ukuran 2 – 3 inci. Pipa yang dipakai adalah jenis pipa PVC karena sifatnya tidak mudah korosi dan biayanya pun lebih murah dibandingkan jenis pipa lainnya.
Sistem penyaluran air hujan memanfaatkan pipa horizontal dan pipa tegak, air hujan diarahkan hingga ke lantai dasar, kemudian dialirkan ke saluran drainase keliling gedung menuju riol kota. Perancangan sistem penyaluran air hujan menggunakan data curah hujan Kota Padang selama lima tahun terakhir yang berdekatan dengan lokasi pembangunan gedung yaitu stasiun pengukuran Alai untuk menentukan luas daerah tangkapan air hujan. Perancangan sistem plambing didasarkan pada SNI 8153:2015. Gedung pengembangan Hotel Grand Zuri Kota Padang merupakan gedung hunian usaha yang terdiri dari dua belas lantai dan dua lantai parkir. Penelitian ini bertujuan untuk merencanakan sistem drainase air hujan untuk pengembangan Hotel Grand Zuri Kota Padang. Salah satu sistem perpipaan yang harus disediakan pada bangunan tempat tinggal adalah sistem drainase air hujan. Total amount of investment of plumbing equipment is Rp 2,157,697,501,- with cost of water supply per unit Rp 4,445,643,- meanwhile waste water piping cost per units is Rp 1,070,711,.
Rain water goes to infiltration well by gravity through designed 1 well.
Waste water use separated system between grey water and black water and then distributed to STP to be treated and reused for flushing water closet and watering plants. Conclusion, significance and impact study: Clean water supply system will implement roof tank system and recycled water will reutilize wastewater for flushing on toilet tank and watering the plants.
Average daily water consumption is 268 m3/day for clean water and 44 m3/day for recycled water with the capacity of ground water tank for clean water is 564.54 m3 and recycled water is 62 m3. In addition to water supply, recycled water system that utilizes waste water to be recycled for flushing closets and watering plants also required to be implemented. Methodology and Result : Plumbing system planning methods are collecting and analyzing fluctuation in water use, planning clean water and recycled water systems by endorsing alternative piping for clean water and recycled water. It applies water supply system which commonly used for tall buildings, namely Roof Tank system. Strong>Aim: This study of plumbing system plan is aimed at planning a plumbing system that is compatible with clean water, waste water and rain water management at Tunjungan Plaza apartment, Surabaya City, Indonesia according to SNI 8153-2015, and meet 5 aspects of safety, security, simplicity, beauty, and economy.
