Water contamination is a result of people's careless attitude toward managing food waste, particularly in
public sewers. During regular dishwashing, a lot of tiny solid particles like fat, oil, and grease (FOG) may
still get past the sink filter and clog the piping system. The goal of this study was to create a conceptual
design for a passive grease trap used in wastewater treatment systems. The best design was chosen using
the Pugh technique, morphological chart, house of quality, and consumer survey. The finished design is
lightweight and portable, measuring a respectable 300 x 430 x 300 mm and weighing around 7 kg. There
are three divisions in the grease trap system. A solid filter is served by the first partition. Since water is
denser than oil, the second partition serves as an oil filter. The last barrier serves to dump any leftover
waste before water enters the public sewer. Because just PVC and mild steel are used, the suggested
design is cost-effective
