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
