MANHOLE ANSWER

MANHOLE COVER

MANHOLE COVER

 

So here is the answer to the question

WHY ARE  SANITARY AND STORM SEWER MANHOLES ROUND?

ANSWER – Because round is the only standard shape that will not fall in on itself.  A square shape, or rectangle, or typical triangle, can be turned so that it will fall into the hole.  A round sewer cover will not!  They are also easier to make.
