Potential Greywater Quantification for Reuse in Newton Residence Apartment Bandung, Indonesia

Newton Residence Apartment is a 3-tower high-rise residential building located in Bandung, West Java, Indonesia. With the total number of 915 units and 47,472 m2 building area, covering 5,349 m2 of land, each tower consists of 22 to 36 floors. Total population of the building (including residents, employees, and visitors) is approximately 3, 245 people.
The objective of this study is to determine whether greywater generated in this building could contribute a significant amount of water to reuse, thus reducing the quantity of clean water pumped from the deep well as the main source.
Preliminary identification found that water generated from washbasin, floor drains from showers and faucets used for ablution, and air-conditioning (AC) condensate, as suitable sources as they fall into light greywater category. The result showed that the high-rise residential building has sufficient greywater quantity potential for reuse to cover all of the 69.72 m3/day toilets and urinals flushing requirements. Greywater reuse could contribute up to 22% of the building’s clean water quantity requirement, thus reducing the amount taken from the current source of deep well pumping, and save approximately Rp. 275,219,453.- per year of the current ground water tariff in Bandung.
