I heard water barrels will be implemented soon, so my idea is to have that as, the clean pure water. As water is sustainable so it can't run out, it should be hard to get (ish). The water barrels is a great idea and I am thinking that because of this, the tap water and toilet water especially should be dirty or limited, but only after like a few weeks or a suitable in game time. The taps should stop purifying water because of the out break and in result of that should start giving out water that can get you infected with the zombie infection it's self or other infections (you could choose to stop taps all together after a certain period of time). (I say zombie infection due to them getting in touch with the water drains.) Heating water should also be a cleaner more purified way to keeping away from the bugs, as I am a new member to the forums and to the game its self, I do not know if this is already suggested.
