Where does the SWL exit the building in relation to this cement box?

[Mark E. Northrup]

Maybe a tornado shelter. LOL
Really i think it is a septic tank that was home made. Built to close to the house

A septic tank, it may be abandon

Redneck covered swimming pool.



Could either be a cistern, or as most post septic tank although I haven't seen one above ground before. Maybe I've just been looking at grass shacks too much?

[Robert W. Jude]

definitely an old septic tank. what it was used for here is unknown. At long as its capped..... whats the problem?

Well Thank you all, we now know what it is...........SEPTIC TANK! THAT SHOULD NOT BE THIS CLOSE TO A HOUSE........ WOW!!! The old house was torn down and the new one was built right beside this septic tank.
Thank you all for your support on this one.
