I think it should read "Disposers" I heard this yesterday and really couldn't believe it. In my former life(as a plumber) and even now, people have asked me about grease in the drain and sewer lines. They usually got defensive when I explained it to them, saying "I don't throw grease down the drain!" Grease is kind of a general term, usually meaning a build up of oils, and even soaps. When people finish eating off a plate they usually wash or rinse the plate off in a sink. Just about anything we prepare to eat contains some kind of oil. This will gradually build up in the building's waste/sewer line, and in the municipality's system. Just because the kitchen sink doesn't have a food grinder doesn't prevent the irresponsible occupant from dumping a frying pan full of molten lard into the system. Maybe it will cut down their "spills in the sanitary sewer system", but not by much. If the Raleigh (and surrounding cities) want to cut down on their city sewer system, they should start a city wide composting program, or even require new residential construction to have individual catch basins, or in house grease traps, that the owner will be responsible for maintaining. http://news14.com/content/local_news/tr ... fault.aspx Other mayor in the county agree on ban as well. http://www.newsobserver.com/politics/story/1001120.html This could also be part of the solution. http://www.naturemill.com/?gclid=CJSAx6 ...
