Discharging to Brick Sewer
Discharging to Brick Sewer
(OP)
We have a project where we will be connecting (discharging) to an existing 54" brick sewer (old but in relatively good condition). Installing a new Manhole is not an option. has anyone tapped into a brick sewer? any tips?? thanks

I have seen lots of plans with vague notes like "contractor shall tap into existing sewer and repair in kind". Contractors often either submit an RFC (asking to use a manhole) or just won't bid the job.
Build a doghouse manhole around the existing, and you might be able to do the job without interrupting flow...bypass pumping for a 54" sewer main would likely be thousands of USD per day.

then construct MH? Liner can be designed to provide structural "support" to hopefully minimize damage to brick sewer.
Good luck

For example, we had to connect to a 42-inch brick sewer by building a manhole structure. The structure's total circumference interfered with a 24-inch watermain. They poured the bottom slab, brought the structure up with manhole block, and poured the sidewall between the 24-inch water and the 42-inch sewer. I've also seen them build up sidewalls with manhole block as well.
Typically, if you run this stuff by the City prior to installation, they don't have a problem with it as long as the structure is properly mudded both inside and out.
