Abstract

This study took place at the East Java Provincial Public Housing, Settlement Area, and Public Works Office. this information highlights a noticeable difference in both size and height between the two sections of the structure. On the other hand, a greywater management system is designed to process and recycle wastewater generated from domestic or building activities, including water from sinks, showers, and laundry machines, but excluding toilet waste (referred to as blackwater). Greywater typically contains low concentrations of soap, detergent, oil, fat, and organic matter, along with fewer pathogens compared to blackwater. As such, it can be repurposed following suitable treatment. Implementing greywater management in eco-friendly buildings can reduce potable water consumption by about 30 to 50%, depending on the building's size and usage.
