Just curious what the deepest sewer invert you have measured?
I measured one today at 32 feet which is the deepest I have come across to date.
That beats me. The deepest I've ever measured was just over 27 feet.
. . . WHAT????
43' AND CHANGE. BRAND NEW, DRY, CLEAN. WHEN I LOOKED UP
I COULD SEE STARS - MID-DAY.

GEEZER
What are you doing 'in' the manhole??????
Deepest I have measured was about 25 feet.
42' change. 100' Cloth tape with 1/2 rebar tied on for weight.
About 45 feet, don't remember the exact number, but we were hoping it was going to hit 50 and it didn't.
A sewer at the corner of First Avenue and East 25th Street in Manhattan, it serves a large interceptor sewer that runs easterly under the East River into Brooklyn's Newtown Creek WPCP.
Talk about being in deep sh........
sorry, couldn't help myself.
geezer- i think you forgot to take your meds again:-D
We had to have one designed and built that was to be buried under about 60' of fill. But then again, it was for storm, not sanitary.
I believe it was 43'+/-, into an large (60" I think) wastewater interceptor line that had been tunneled, with about 2' deep flow running through it, therefore the +/-! We used fiber tape with 4lb hammer tied to it. Near I35 and Riverside in Austin.
Hep 'n ol' country boy out. Whut's a sewer? An' whut's a invert thingy? I reckin y'all ain't got no privvies 'n warshup bowlz nexta da pichur pump.
Over 100'
The 100' tape wouldn't reach the bottom. How they got their depth, I don't know. It was before my time with them.
They had already gotten to the bottom for a measurement but couldn't measure the diameter.
I had just been hired and was asked to go down for a measurement. Not having a clue what I was being asked to do, I went along with it thinking maybe 20-30'.
WRONG!! When I pulled the lid and looked down, I just looked at the boss and said "hell no, I ain't going down there".
He already had the depth but needed the outflow diameter. Me and the boss found where the outflow came out so we crawled in. This was storm not sewage - thank God.
It was a super hot day in mid-summer but once we got in the pipe about 30' it got REAL chilly. By the time we made to our measuring site it was downright cold.
The pipe was big enough for us walk hunched over. A hobbit would have been just fine.
Personally, I hate going underground so I was really happy to be out of there.

We NEVER go down into ANY type of structure anymore without using the confined-spaces entry procedures and gear. You wouldn't either if you took the classes. Since we started using the procedures we have had to ventilate at least one water vault which tested low for oxygen before entering. We never would have thought twice about going in there before - I suppose the EMS would have pulled our guy out unconscious or dead - maybe more than one guy if somebody went in after him...
very serious stuff dealing with sanitary sewer manholes, espcially on a trunk line. years ago we were relieved of popping lids and doing inverts for city of Tempe on a trunk line - city decided they should have their crews with the special breathing apparatus do these, even tho they never entered the manhole. lines were somewhere over 25' deep (our 25' rod wouldn't touch bottom). first few we opened, the fumes were strong enough to just about knock you out. I was a new guy back then, and was told to get the invert - when I didn't hit bottom with the 25' fiberglass rod, we knew we needed help. it was hard just to hold my breath long enough to lean over and lower the rod. one part of the job we all hate.
early 70's,I went down a 32' sanitary sewer manhole.Manhole was made of old red bricks.One thing nice about being heavier,I probably would not even fit!!!

70' on east side of Queen Anne Hill above Lake Union in Seattle. It wasn't dug, but was constructed in spiral brick above a 10x10 square sewer tunnel as they filled above the lake level there. I measured it (approx) with a 100' rag tape with about a dozen railroad spikes wired to the bottom
42'-43'
It was a new manhole, still dry & clean.
It was approx. 4' in diameter, with no steps. A small piece of plywood was attached to a couple chains and secured to a small crane. I rode down to the bottom on it. No hardhat, no safety equipment, nada....
This was early 1980's...
I can explain it to you, but I can't understand it for you...
Not to worry guys. I very well know about the confined spaces business and want no part of it. Just like my issue with heights, I have an equal problem going underground.
Had I known how deep it was I would have declined immediately. If it would have been a sanitary sewer I would have laughed at them.
I have pulled a few lids where the smell about knocks you out. One made me puke almost instantly.
Exactly Hillbilly! You're asking for trouble (along with hefty fines in this area) when entering any underground facility, especially sewer manholes.
Well, I surveyed 300' down an active gold mine....but that doesn't count; not a sewer. (just thought I would brag).
