Bar Screen in Sewer Manhole
Bar Screen in Sewer Manhole
(OP)
We are working with a sewage district that REQUIRES bar screens in sewer manholes under certain circumstances. Primarily, they require bar screens in the uphill manhole just before any steep section of gravity sewer. This seems like a very bad idea, with a lot of headaches for the system operators. We have not even been able to get a response as to why they want this item.....it is just required, period. Does anyone else out there know of districts requiring such a feature (disaster!) and why? Even better, can anyone link me to some logic or codes that address this issue?
Thanks
Thanks

I do think that it would be prudent to point out that the sewer is considered a confined space and for that reason, it would be very difficult and expensive to service such an installation.

Thanks for the suggestions. I should have stated that the district is the reviewing agency, our client is a major developer, and wants to operate and maintain the water and sewer systems themselves (having many such systems around the country). Therefore, while in general I agree with the suggestion that we just comply with the reviewing agencys requirements, (and having been part of such agencies myself in the past), I do not want to create a headache for our client, and a possibly dangerous situation for the client's operators. If I could get the reviewing agency to simply state why they want bar screens in manholes, I might be able to logically understand, or conversely, to explain better the logic against them. However, I am faced with a "do this because we say so" stance that I find very hard to deal with. Thanks, and any additional comments would be appreciated.

We had the option of either installing a muffin monster or a bar screen, the client preferred the screen. It's not a perfect design, but it satisfied all those involved.
