Can someone please help me my dad has a manhole on his street that continually overflows raw sewage into his yard at least 2-6 feet each time and it floods his shop and the lower part of his home. We can't get anyone from the City or EPA or DNR to help put a stop to this they just say they are working on the problem but the thing is it's been happening for like 7 years but the past 2 years it's got really worse. The smell is sooo awful and I can't understand why this is not being treated as a dangerous health hazzard for our family. What can we do about it. Thanks
