There's a concrete/masonry truck (CPM - Commercial Plastering & Masonry Co, INC.) that loads up supplies every morning/afternoon at Morris and Iseminger. This morning I saw for the second time members of the crew/owner shove trash into the sewer grate. The first time it was a bag of trash and this time the guy was about to sweep a whole bunch of trash into the sewer. I asked him if he was planning to sweep it into the gutter and he said, "Of course I am."

I'm happy people want to clean up trash, but shoving it into the sewer drain is obviously just as bad if not worse! Is there any recourse for this? I'll post it on Philly 311 but I was hoping someone else had some input on this kind of thing. Obviously CPM isn't the only offender, but I confronted them and they acknowledged what they were doing and that didn't care.
