water treatment plant dont work as suggested (wastewater)

Issue description

When you stop dumping wastewater from the water treatment plant the health of the people go up. The opposite behaviour is expected.

When you stop to pump wastewater in the ocean, the polution drops --> more healthy people altough the wastewater stays in the settlement. :)

Reproduction steps

• built a water treatment plant and connect it with fresh water and wastewater
• check the healthy of the people after a few month
• now delete the recipe of the sewer pipe or disconnect the wastewater in some other way
• check the healthy of the people again after a few month --> healthy is now better!

Game version and build number

Forget to write down the unity production dont drop when the water treatment plant dont work correct.

yeah the tradeoff is kinda a silly: if you dump waste water into the ocean, it causes pollution. however, if you don't dump it, for whatever reason, doesn't affect their health and (I think) just lose a small unity bonus. I do agree that sewage overflow in the city is far greater health problem than dumping it into the ocean. when the poop backs up, there should be a serious health penalty. personally, I just make sure it never backs up by putting a tank to alert me when it's not getting drained properly.
