I hadn't previously thought about THAT particular problem...


A few years back when the Howard Hansen dam up in the Cascades was at risk of failure in a major storm, flooding the Kent Valley, one of the major risks to my home in Bellevue was sewage backflow all the way from the sewage treatment facility five miles away - my house was well out of the flood plain, but the force of the floodwaters hitting the sewage facility could force sewage back along the pipes into every house connected for miles and miles. We had a sewage backflow value installed to prevent that. No flood, fixed dam, problem solved - at a modicum of cost I had some additional peace of mind against the worst case.
