The clay trap has been installed under the sink in the janitor’s closet. You can now wash out bowls and such in the janitor’s closet.
Please be judicious about how you use the trap. Clay settles out of water, and if you just let your work water sit, there will be clear water on top for folks to use in a couple of days. And, we can put the clay that settles out of work-water into the recycling.
So – use the sink for minor, final clean-up.
Still no glaze water down the drains. Carrollton doesn’t want glaze chemicals in their water system, and you couldn’t guarantee that that would settle out into the trap instead of getting flushed into the water system.
