Benjo,
I work at a municipal wastewater treatment plant and I don't see how this could happen! Both potable water plants or systems and wastewater plants are totally seperate. One possible way this could happen is to have a flow of wastewater through a potable line and it would have to flow through a backflow preventer to contaminate the system. Another way is for the Treatment plant to discharge partially treatment wastewater into the intake of a potable water treatment plant and then have the treatment plant fail to adaquately treat the water. Both of these are possible but in this day and age HOPEFULLY not happening too often. As a professional I hope to never see this in my area. Hopefully this will get cleaned up fast and they never let it happen again. Good luck.
