Thanks for any input. Let me begin by saying I know NOTHING about the plumbing in my 100+ yr old home so let me provide you with some information. I have a stone block foundation that has leaked since the day I moved in so I'm not a stranger to seepage in my basement. Lately though ANY time I use the washing machine, dishwasher, shower or even flush more than once in 10 minutes I get a POOL of water in my basement that SMELLS horribly! Definitely a sewer smell. Upon investigating, it seems to be slowly leaking in from under the cement floor forming a little pool. I have a sump pump that spews the smelly stuff out when it get's too deep which doesn't make ANYONE happy. I have this covered, brick, cylidrical basin thingy under my back porch that I think is what fills and then shoots to the sewer that I've emptied -GROSS- but I still get the water and the smell. It's very near where the smelly stuff is coming up into the basement. In addition to the seepage and smell, 2 of my sinks don't drain and I hear gurgling sounds from them even when I'm not doing the wash. I think I'm looking for guidance more than a solution. I can't live with the smell anymore. Because even when It's not leaking,IT SMELLS! Thanks again for any attention to this matter! Cathy

I think you've got more than one issue going on.

For a basement to get - even a lot - of groundwater is one thing, but sewage is another.

So this yuck is definitely not backing up through the floor drain?

Definitely NOT coming from the floor drain. Its coming from a crack in the floor that is right near the sewage basin outside of the house

Then get as many contractors as you can out there to give you
1. A good explanation of their method of correcting it (there are a few different ways that you will hear), and
2. Their price to do it.

Don't settle on 2-3... get at least a half a dozen.

There is no do-it-yourself (or even close) solution to the problem.

I'll Do That. Thank You Thank You. Just For Curiosity's Sake. What Do You Think It Is?

Hi Cathy,

You ask,"Just For Curiosity's Sake. What Do You Think It Is?"
You say, " I have this covered, brick, cylidrical basin thingy under my back porch that I think is what fills and then shoots to the sewer."
What sewer? Septic tank or city sewer? How big is this "basin thingy"? Your septic sounds like it's loaded and needs to be pumped or replaced. As for the gurgling it could either be a blocked vent or blowback from a loaded septic system. Rick gave you good advice about calling in a plumber to let you know exactly what's wrong. Please keep us advised. Good luck. Tom

Had a bit of bad luck and so I'm just sourcing plumbers right now. I'll keep you posted! BTW - I'm on a city sewer system and this brick "basin" is about 3 feet across and 5 feet deep, tapering smaller near the bottom. It's outside at ground level, covered w/ a "manhole" like cover. It's filled with lots of smelly, icky sludge. My house is 102 yrs old. I'll post info as I get it! Cathy

Hi Cathy,

Your brick pit sounds like a grease trap that catches and holds the grease from the kitchen sink and soap from the washer before it can get into the septic tank and clog up the drain field. While you may be connected to the city sewer at the present time I guarantee that back then the house was connected to a septic system. What you can do at this time is bypass the brick pit and discharge directly into the city sewer.
At the same time you might wish to snake out the sewer line. Sounds like it's backing up and leaking out from a cracked pipe of a faulty joint. Hope this helps and thank you for rating my reply. Tom
