STUDI PERENCANAAN SISTEM PLAMBING PADA GEDUNG KANTOR LINTECH TOWER SURABAYA

Piping systems are an inseparable part of any high-rise building. Piping systems are used for various purposes, including providing purified water. To meet the purified water needs of the Lintec Tower Surabaya office building, planning of a purified water distribution system is required. For a 6-storey building, 187.2 m3 of purified water is required per day, depending on the type and number of piping equipment. The bottom water tank (underground) has a capacity of 21 m³, while the higher water tank (rooftop) has a capacity of 8 m³. According to the calculation findings, a transfer pump with a flow rate of 9.6 m³/hour and a pump head ranging from 7 to 36 m is employed to convey water from the lower water tank (underground) to the higher water tank (rooftop). The gravitational potential energy of the water from the higher tank can be harnessed for the distribution of purified water to the sanitary fixtures on each floor.
