The government seeks a contractor to supply two ADR-certified high-pressure flushing and suction-pressure tanker trucks for municipal and industrial sanitation tasks, including sewage removal, pipe cleaning, and hazardous spill response. The vehicles must meet strict specifications, including a heavy-duty 6x2 chassis with at least 28,000 kg GVW, a 14,000-liter tank with a movable piston, a vacuum pump with 1,500 m³/h flow, and a high-pressure water system delivering 300 liters/minute at 170 bar. Each truck must come with support equipment, a wireless remote control, and all ADR-required safety gear. The contractor will also provide operating manuals, initial training for up to five government personnel, and a minimum 12-month comprehensive warranty on the tanker body and integrated systems.
