The plumbing installation system with water conservation aspects at X Hotel aims to distribute first class clean water, dispose of the wastewater to a treatment site with appropriate water requirements refers to SNI 03-7065-2005 X Hotel required 114,640 m3/day of first class clean water, and 91,71 m3/day of the total wastewater discharge, includes 18,35 m3/day of black water and 73,36 m3/day of gray water. The X Hotel has additional alternative sources of water condensate from air conditioner (AC) about 44,16 m3/day and 52,53 m3 of rainwater, that can be used for water closet and urinal flushing in the public area at the Hotel, after through the anaerobic – aerobic biofilter STP (Sewerage Treatment Plant) and membrane filtration unit.
