In Milwaukee we have another overflow that happened in Oak Creek a tributary of Lake Michigan for 5 hours. Across the country this has been an increasing problem due to higher than normal rain levels. With the high rain count this plays a part in soil that breaks away around the sewer-pipes and that causes the pipe to be jostled around and this can cause corrosion from the moisture and then cracking or breaking from the movement and moisture. If you are concerned if this could be an issue for you please givePerma-Liner a call at 866-336-2568 or visit our website at www.perma-liner.com.
