So there was sewage on my lawn.
There is not sewage on my lawn any more.
Nor are there roots in the sewer pipe, thanks to the nice fellas in the quickly-dispatched utility truck. Yay city services! Also yay plumber who said on the phone "Where outside? Hm... try calling the city, they may take care of that for you." (Non-yay for the disconnected "if you are experiencing a sewer backup, call this number," but the woman who answered the main Public Works phone got me immediately transferred to the right place so that worked out okay.)
