People say if you clean your gutters, make sure sub pump is working, have a generator back up you won't get water in basement.

Is there anyway to prevent sewer back up?

Install a one-way valve in your sewer line.

Sewer line back flow preventer or back water valve, some communities require them. Here is a link to more info:

If the sewer pipes are under the floor of basement get a standpipe. Or you can install overhead sewer pipes but I imagine that would be expensive. I have had the pipes under the basement floor and now I have overhead. With overhead you pretty much cant get sewer backup.

If you have an overhead sewer system, like almost any new house constructed today, you are very unlikely to get a sewer back up in to your house (I think it's pretty much impossible under any reasonable scenario). I like that option better than a backflow preventer valve, since those valves can fail and just provide a handy spot for solids to build up and clog your sewer line.

Also, you are much more likely to get sewer backups in neighborhoods with combined storm and sanitary sewer systems. We have separated sewers in my neighborhood, and most backups are due to illegal connections and problems with individual home's laterals.

My suburb has a cost-sharing program for both overhead sewer conversions and backflow valves. I know that a few others do too.

How much does an overhead sewer cost? Why doesn't every one in suburbs such as wilmette and park ridge get an over head sewer to prevent sewer water. 26% of homes in wilmette got sewer water when the major rain storm happen.

It really depends on the configuration of your house and lot (How long is the run? How deep? Is your existing plumbing stack near an exterior wall that can be penetrated?). But I've heard of bids between $5,500 and $12,000. My own house was closer to the low end of that. And like I said, some suburbs have grant programs to help with the costs.

I will also add that I know a guy who got a backflow preventer valve in Elmwood Park, and he came home from vacation to find four feet of water in his basement. Those valves can and do fail. I'd personally go with the overhead sewer conversion if I had a chronic problem.
