The garment comprises an outer barrier layer (101) formed of Polyvinyl Chloride (PVC)-coated waterproof fabric, an inner breathable cotton lining layer (102) for moisture absorption and wearer comfort, and stitched seams (104) sealed using heat-activated seam sealing tape (103) to prevent leakage through needle perforations. The garment is configured as a full-body coverall or a jacket-pant assembly and includes sealed closure mechanisms (106), covered zippers (107), elasticized cuffs (108), and a neck sealing portion (109) to prevent ingress of contaminants. The synergistic integration of waterproof barrier protection and internal comfort layer ensures liquid impermeability while maintaining ergonomic flexibility and prolonged wearability in hazardous sewage environments. The garment is reusable, durable, and suitable for occupational sanitation applications."
