Anyone Got a Good Nose?

The smell that was present last year, adjacent to the entrance to Kilcullen Business Campus, has returned. It might be gas or sewage, I'm not sure. It could be sewer gas released from a vent.
There's a mark on the road surface, extending from one side of the road to the other, where it was re-tarmacked after a service was laid. So that may be where the gas or sewer line runs under the road. The smell is coming from the area where this service enters the business campus, behind the timber fence to the right of the main gate.
My sense of smell has deteriorated because of COVID, so maybe someone could confirm if the can smell anything?

I'll have a look at the Gas Networks Ireland map to see where the gas line enters the site. I rang either John Craddock Ltd or Murphy Geospatial last year, can't remember which, to enquire whether there's a management company for the business campus. But I was told there isn't.

Is it council owned?

Another possibility is that there's a sump (a holding tank, that acts as a reservoir for sewage until the sewers can take it) near the entrance and this has a vent that releases sewer gas, just like a septic tank.
