[GreenYes] Food debris belongs outside the pipe.



Alan,

First, I own no stock in Dispose-All or other machines that chop food waste to the sewer system.

However, I'm curious to learn more about the nature of the sewage disposal problem. In my experience, most raw sewage hits rivers during wet weather events, when massive volumes of runoff overwhelm sewage treatment plants; or due to undetected or uncorrected illegal discharges. These problems would not be affected by whether or not some food waste is in the system. Similarly, most problems with effluent and sludge quality seem to be due to industrial discharges of chemicals, not the inclusion of a wider array of organic, biodegradable wastes. Is the experience in DE different?

I think there is a sort of historical/technical revisionism going on
here. We always heard about how great sewers are. Now we are
beginning to see that we replaced stinky outhouses and cesspits and
honey wagons with massive surface and groundwater pollution. (In
2006, Wilmington Delaware still dumps around half a billion gallons
per year of untreated sewage into rivers....)

The "disposall" people seem curiously silent on the need for better
sewage treatment, even as they want us to use their products to add
loads to the systems.... When they show up in Delaware and help us
fight this battle I will be more receptive to their arguments on this list.
