Used coolant (non contaiminated) can be disposed of down the drain at some water treatment plants. Ie. Phoenix. You will need to call the your water treatment plant to confirm or pay for it at the local solid waste facility. But that is just the waste coolant. It is perfectly legal to let the flush go down the drain (3% of containments is what the EPA reg allows iirc). If you really don't feel like that you can collect the flush and let the water evaporate and just throw away the solid salts that are left behind.

Sorry it took so long to post some photos. We've been in the middle of a super cold snap and it's been tricky to time taking a photo etc...
I'm not sure how helpful these will be... I will try to suck a little fluid out into a clear container in the very near future and post a photo of that too. The coolant is a little brownish, which is what prompted me to start the thread. It's only 6 months old, so should look as-new. It was much pinker and cleaner looking right after the service 6 months ago.
