Most US cities have two seperate systems.  Sanitary sewer for waste and
storm sewers/drains to handle  storm water.   Some cities in the SW just
have sanitary sewers, as storm drains would have to be huge....... Carlsbad,
NM being one, just build streets running toward the nearest river (in
Carlsbad ... the Pecos River) 12-18" lower so the torrential rains just turn
the street into streams and heads down the streets into the river.
