Domestic water consumption is affected by various factors such as number of households, type of house, and occupation. Moreover, depending on the type of technology used such as water-using appliances and fixtures associated, consumption for a specific household routine can differ greatly. However, in Malaysia, there is a limited study on water consumption patterns by different household routines. In this research, the household routines parameters are identified via various literatures. It is then complimented with the secondary data collection in Seremban, Negeri Sembilan to yield pre-determined values (low, medium, and high) of domestic water consumption parameters. The final values are then determined to produce static pre-determined water consumption values for each parameter. These values allow more insight towards accurately estimating or classifying domestic water consumption.
