Catch Basin Manhole Replacement Questions

[pizza]

i need some advice on fixing this hazard. i believe it's called a circular catch basin – is that right? or manhole?

i believe this access point is for a storm drain that probably incorporates an adjacent driveway drain, and it communicates with my house sewer because i know it's possible to rod out the sewer from here (going through the house and then out to the street / city sewer). i hire plumbers to do this every so often because tree roots are bad around here. however, now i have a tramco backflow preventer setup in my basement (unsure of precise name for this style of system), so you gotta lug the machine downstairs to a cleanout just downstream of that.





the steel manhole cover is gone. i don't think it actually fell in the hole because i looked with a bright light and can't see it down there, but i'll try dangling a magnet on a string for fun. i have a pretty good idea of who probably stole it. oh well.

it was a solid, circular, steel cover, btw. not a grate.

the cover was kinda wobbly on there though, so it's time to replace it before someone falls down there and takes my house. lol
for now, i have an oversized obstacle that does a great job of covering it.

i got one estimate so far:

Replace Basin Ring

Remove broken catch basin ring.
Provide and Replace 30" concrete catch basin ring and steel cover
2 men, all day

$3700

what do you think of that estimate for chicago?

how DIYable do you think this is?

any recommendations for suppliers for a ring and cover around chicago and what they might cost?
i found one promising lead so far:

Franklin Park Building Material | Precast

Patio Block | Chimney Cap | Catch Basin Cover Ring | Rock Faced V-interlock block | Fire Department Stamped | Smile Stamped

www.franklinparkbuildingmaterial.com

besides the ring, steel manhole cover, some bags of concrete, and something to mix concrete in, what tools and supplies might be involved? what would the procedure be?

also, what was the failure mode? the concrete shifted/settled for.. unknown reasons? freeze-thaw, something-something?

thanks, guys

on the other hand, if i leave it to the pros, what should i ask for / specify to hope for a lasting, high quality repair?

I've seen concrete manhole covers. Maybe not on a driveway if that's where yours is.

 

[pizza]

that's not quite where cars drive, but it's a path that's kind of part of the driveway.

You received the "we don't really want this job" bid. If it was my problem, I'd probably have one of these (or something similar) https://www.jmesales.com/morrison-bros-18-in-318-series-manhole-w-tank-monitor-on-cover-12-in-skirt/ shipped my way, rent a demolition hammer if you don't already have one, and go to work. You'll be able to gauge how many bags of concrete you need after you get the old deteriorated stuff out of the way. Looks like an easy $3,000 savings to me.

Break out the old collar and figure out what size would be best. Order a new collar ring with spacer rings as needed to get up to grade. Embed that cast collar with riser (if that is the type you buy) with the manhole cover that goes with it. Grout the voids.

 

[pizza]

so don't bother replacing concrete around it except for what's already broken in chunks? no need for a concrete saw, a jackhammer, a compactor for the backfill, etc? if not, then it's becoming a more realistic project for me lol

i guess i could rent tools though

found this vid which is like a more intense version of my project

i was imagining a cutout like this, but maybe this is way overkill:


or is it? no idea how far back to go (if at all)

Before you do anything you should probably call your city or county or whoever is responsible for the sewer system. Make sure it isn't part of their system. They might come out and fix it for you ?? In this area the county is responsible up to the cleanout.

I agree. If this is somehow tied into the sewer, I would not consider touching it. But having it also include the stormwater is very odd

Not really odd considering the age of it. Storm water run off and sewer were together as a norm until the EPA mandated separation.

Many places are still trying to get separation accomplished. Hard to do when it was done that way for 80-100 years.

The problem with involving the public agency is what you may be required to do and what the cost is. They may absorb the cost, defer it (partially or totally) to you or tell you it needs fixed to "this" standard.

I'd try to replace the concrete riser with a new one and lid.

You could also possibly cut brick, block or pour a new one. Leave 1/2" shy of level and have a fab shop cut a piece of steel on the plasma table for a cover.

^^^^^

If it is part of a pubic utility system on your property they WILL have standards that it needs to meet. The pipe underground may also need to be worked on to meet new watertight standards as well if sanitary sewer (lined or new, like we had to do in the Tahoe basin for about 60k). They may have or now require easements for their systems as well.

Do what research you can to figure what it really is, where it is connected, who it serves and who it actually belongs to. That will help you decide if you should contact some agency or what effort/cost that may need to be done. It also may determine if you should leave it alone as well because there are some costs or hassles with touching it.

it was for sure the old place to snake out the sewer before i got a backflow prevention system.

i could be wrong about the storm drain thing, but if i'm right, then it's grandfathered in.

it's part of my house. it's hard to imagine it belongs to / serves someone else.

i need to repair this because it's a hazard, and i'm tired of my makeshift obstacle obstructing the walkway. leaving it alone isn't an option.

how much (if any) concrete would you cut out around it?

is this overkill? assuming i'm looking for a proper repair i guess

 

[mike93lx]

I wouldn't cut anything without the new cover on hand. Then go from there

Mine is almost at the garage door 50 feet from the street and the county in responsible for it. Some houses in my area even have them in the back yards.

If I was going to fix it I would take out the entire round part down a few inches. Make a form out of thin plywood and repour a new one. Have the new grate on hand and you could cast the step into the concrete for the grate to sit in.

 

[tarmy]

If it is yours/private then tear it down to good/solid rim material (as noted you should buy all the likely replacement rings and rim ring/cover and have it on hand) and start grouting in the new rings and final rim. Bring it to grade and post a picture

There is a place called Henery Frerck 3135 N Belmont that sells the ring. Catch looks good like its been relined all they do is smear mortar over the brick or block. They do sell catch bason block. most older ones are brick.

There's nothing wrong with doing that big section, but it's not necessary and the only material benefits you're gaining are a more strenuous workout and higher cost. Keep in mind that you don't know what is under that concrete. You could be opening yourself up to a much bigger problem. Shouldn't be, but you never know. If it was my problem, I would just remove and replace the damaged ring section, install a new riser/lid, and be done. However, this is your problem and one of the things you should consider is how comfortable you will be with the repair. If doing the full section you outlined will let you sleep better at night, there's really no counterargument to that.
