If I remember correctly the new DIA airport has a state of the art
recycle system for deice fluid. As I understand it the area where they
deice is a very large tapered bowl, kinda like the floor in your
shower, all excess stuff makes its way back into a sump underground,
then its pumped to a series of filters and separators, that fluid is
then recharged with new glycol to bring it back up to specs. It
supposably is able to reduce the need for new stuff by over 60%. But
then, this is the airport that spent hundreds of millions on a "state
of the art" baggage handling system that turned out to be the biggest
failure is dollars next to the "big dig" in Boston.

For the other poster that wanted to know the amount of deice activity
at KJAC, last year they went through over 200,000 gallons of fluid for
all activity, GA,majors, yada yada yada.... I live just a few hunderd
yards from the airport and I LOVE aviation but lately whenever I drink
some water I wonder what the implications of this stuff is as it
travels through the aquifer and into my well..

Hmmmm,,, Type 1 deice fluid costs are about 11. bucks a gallon, thats
the applied price to planes here at Jackson Hole Wy. He got off REAL
cheap if the bill was 3600 bucks. His bill here would have been
20,250.00 or more $$$$$$$$$$$$$$$ dollars, And,, if not recycled
thats alot of stuff going into the surrounding soil... Per Plane
!!!!!!!!!!! YUCK.

I'm not sure how deice fluid would be recycled, the airport I worked at
had a glycol trap on the main ramp that was routed to the sewer during
the winter, then during the summer the valve was set to drain
(rainwater) to the adjacent marsh.
