Can filters or screens be installed at the inlets of detention ponds and storm drains?
It sounds like a good idea. But during a rainstorm, trash is quickly swept to detention ponds and storm drains and any screen or filtration device placed in front of these structures would cause trash to accumulate and clog the grate, preventing proper drainage and end up flooding the street. With hundreds of miles of pipes and channels in the system alone, there would be far too many blocked detention ponds and storm drains to have crews cleaning them as the rain falls.
