"... if the facility is connected to a sanitary sewer that discharges
to a Publicly Owned Treat-
ment Works (POTW) and the wastes will mix with domestic sewage, the
waste antifreeze may
be disposed in the sanitary sewer on-site." - Missouri Department of

"Flushing used antifreeze down the drain is the least-preferred
disposal option, but it may be the only option available in some
areas." - Colorado Department of Public Health and Environment

"California law restricts disposal of used antifreeze in landfills,
through storm drains, and into sewage systems. Check with your
hazardous waste permitting agency and your sewer regulatory agency for
details on restrictions."  - California Dept of General Services
<http://www.green.ca.gov/EPP/Vehicles/Antifreeze.htm>

Small quantities of antifreeze (i.e. any amount your average car owner
might dump from a car or two) will have no adverse effects if the
water is treated through a modern  two-stage sewage treatment
facility. Granted, recycling is preferable for a myriad of reasons,
but down the toilet into sewage treatment is prefferable to letting it
run down the driveway into the gutter
