Could you take it out of the bag and take a better picture?

if you've bought a yard gulley, and it looks by the grating that you have, it's a bucket to catch the silt prior to it entering the pipework

just seen them in upper middle of pic

That's what it is then, Ill get it out of the bag next time I was just passing and making sure the trench hadn't filled with water. Don't know what I would have done if it had tho!
