Mechanics sink needs a look
With all of the recent changes to pollution mechanics, the Sink needs a rework. Because pollution now lowers housing scores, no one in their right mind would install a sink in their house. You would come back 24 hours later to find your entire housing score reduced by 25% due to pollution.
Ideas:
Differentiate between "greywater" and industrial sewage and add a lower-tier waste filter in the Mechanics era that treats greywater without requiring Basic Circuits.
Allow a septic tank or buffer container to hold sewage, similar to how garbage bins work, where it can be picked up and hauled away.
Note: Both of these ideas also open the door to having other household fixtures produce liquid waste, for better or worse.
Or just keep it simple and remove the waste pipe requirement from sinks entirely.
