A fact not known by much of the population of the city is that almost every time it rains, the sewage treatment plants release raw sewage into the ocean. This is due to the storm drains being drained by the same system that sewage is treated from. Due to this the water is filled with trash, floating condoms, and wet wipes. So this isn&amp;#x27;t just third world countries. It is bad enough that bacteria and nitrogen wastes get into the water when this happens. They should at least capture the trash and disgusting sewage products.</text></comment>

With the latter, you pop open a manhole cover and suck out the goo with a vacuum truck.  With a net, you have to somehow pick it up without spilling the contents. Then you hope you can empty it without destroying it or you replace it.  This sounds much harder.&lt;p&gt;Oh, and hydrodynamic separators claim to catch oils, too.</text></comment>
