The image shows three people working in a large industrial setting. They are gathered around a large yellow tub filled with water. The tub appears to be made of concrete and has a cylindrical shape with holes on the sides. The person in the center is holding a white pipe and is pouring water into the tub, while the person on the left is wearing a green jacket and a headband, and the person next to him is wearing an orange shirt and a black baseball cap. On the right side of the image, there is another person wearing a blue plaid shirt and is looking at a piece of paper. In the background, there are pipes and equipment hanging on the wall. It seems like they are working on a project or analyzing the water in the tub.
