I bought a house built in 2005. It doesn't have gas (runs on gasoline/mazout), and doesn't have separate rain and sewage yet. Still, it has these two cilinders at the front of the house. I'm not sure what they are and haven't dared to open them. Any guesses what they are? My current best guess is an inspection pot for sewage and/or the water meter.

Looks like one of the sides of a french drain. You can use this to flush the drain in case of a clog.
Ventilation tubes for the basement?
