Household Septic System

[farmer2009]

Time allowing, I may dig down to the drain line and follow it to the tank wall. Then based on the tank dimensions I'll measure in to locate the lid. Sent from my iPhone using TractorByNet

Once you have it dug up next to the house enough to determine direction then probe for it. Allow a little fall for flow but every 5 feet you should be able to find the line. As you will know about how deep to probe.

If anyone is still watching and curious about progress....

Located the 3" drain from the basement. Dug a hole about six inches out from the wall and 20" deep to top of the drain line. 15 feet out from there is that flat rock in my original picture. So technically that would mark the drain pipe entry to the tank. Started digging there to locate the same drain line. Expecting it to have a few inches of drop from the house so the hole will be a few inches deeper before I strike the drain. How far below the top of the tank would the drain enter? in other words, if the drain is 24" below grade, how far below would be the top of the tank? seems like it wouldn't be more than 18" deep at that point. Almost there...

5'hx 4'w'10'L plus eight inches each for 4"thick walls and floors.

After what I learned today, I'm suspecting that 15 feet from the house is already long past the outside edge of the 4' wide tank. That would be why I didn't find it in those 42" deep holes I dug earlier this week. A-Ha!

Inlet pipe will come in just under the top of the tank so just under the four inch thickness +/- of the tank top. The outlet pipe is a couple of inches lower to allow the flush to fall freely into the tank.

Got it! Hit the tank top at 13" deep about 8' from the house. So that's why we couldn't find outside of the 15' on the sketch. The tank top is approximately 5" higher than the drain line at the house.

Now to find the flippin' lid...

Ta Da! Congrats. Finding the drain line was a good first step.

A concrete riser on the lid is a good thing. You could grade around it so it ends up flush with the ground, mow over it except for the handles maybe, won't stick out like a sore thumb. You should be able to buy a riser where they make and sell the tanks.

My tank has one central pumping lid and smaller access lids at the entrance and exit. I put a riser on the center lid and cut 3/4" pvc conduit pieces to stand vertical and flush with the ground on top of the other two for markers that don't rust or rot. Back-filled with stone dust makes easy digging for the entrance and exit hole lids.

If you raise the lid close to the surface, then the soil covering it may be to shallow and dry to support lawn.

It's a trade off.

I wouldn't cover the lid, just make it even with the ground. I would gladly look at the lid in exchange for easy access anytime with no hunting or digging. It can be painted green.

My daughters new tank was installed with plastic covers that are flush with the lawn. have to remember to not mow over them and really remember to not drive the 5045E over them. Of course they are in the perfect place to drive a load of wood around to the walk out door. :thumbdown:
Glad you found yours.:cool2:

5" higher then the top of the drain line or 5" higher then the bottom of the drain line?

 

[jlgurr]

The best news then, may be that it is under the deck where we have 3/4" gravel over the dirt. So we don't need to worry about grass growing there. The red clay was so dry it is like digging a hole in ice for ice fishing. It really seems just a tad bit less hard than concrete. It will be a few days before I can dig some more anyway since it's going to be frigid here tonight, like 20F. The deck floor is about 8' above grade (second floor of house) so we will have easy access in the future. Was thinking of marking it by driving a nail right above the lid and simply hanging a plumb bob from that to see the hole next time we need it.

 

[jlgurr]

5" higher than the top of the drain line. This is only a guesstimate based on the slight drop in grade from where the drain line was discovered.

Is a tank with three lids common? Should I be searching for the center one? This ground over the tank is so hard there is no way I can dig here and there like I was in the yard earlier this week. I was hoping to use snowed in's tank dimensions to get me close for finding a lid. What diameter would the lid be?

LOL! I don't ever recall working this hard to find a pile of crap.

That I believe with some allowance for not shooting the grades with a level. I like your idea of the nail and plumb bob but would use a screw in eye bolt and add a good durable label next to the bolt so nobody would think it useless and pull it out.

Ya, it's not a great prize for all your efforts.

Tanks come in different configurations. Some have separate chambers with separate lids and both need to be open for pumping. Mine has baffles mounted high in the tank but below those it's just one open tank, one pumping access lid.

You won't know until you finish your treasure hunt and get it opened up to see what's what.

I think my riser is about 24"-28" in diameter. It's under the snow or I would put a tape on it.

Our septic pumper has a 100' of hose on the truck, they don't have to get real close.

 

[vtsnowedin]

Mine has three. Small ones over the inlet and outlet pipes and a 24' or so one in the center for pumping out. My daughters twenty five year newer one has two equal sized covers brought up to ground level but there may be smaller ones they just buried on the ends. I Don't know why they need two to grade. New crap isn't any different then twenty year old crap.

 

[farmer2009]

Glad you found it. I know mine has two lids. I had one uncovered when the pumper showed up when I had it pumped shortly after buying. He said wrong lid and stepped back a couple of feet and dug up a different lid. But he remembered when the tank was installed. Evidently he had a hand in the installation 10 years earlier. The one I dug up was too small he said.

I would recommend you do not put a riser at ground level that is more than 6" in diameter. One that is larger, well, curious kids and accidents have left many young folks dead in a pit, septic tank, dry well, etc... Better to measure to the center of the lid from two corners of your house, document it, then bury it again. Its a rare occurrence, but it seems to happen every year or two around here.

That's something I never considered. No child will lift the concrete lid on my riser, but ... that's my tank and lid, from 2006, not 1978. Good thing to think about David.

Septic Protector
In the 1990's many states began to realize septic systems needed to be maintained but people were not doing it, so they began requiring easy access to the tanks. What this meant is they used a riser to bring the access port up to the surface and a cover placed over it. At first they were made out of concrete but there were a few problems: First they were ugly. Second the concrete would breakdown from the sewer gas. Third, they were heavy and hard to work with. So manufacturers began coming out with plastic risers and covers...but now we are seeing problems with these.

The plastic can get easily damaged when hit with a lawn mower, cracked in the cold, retaining screws strip out and the UV light (and sewer gas) can make them brittle. Now what is happening is children are stepping on them and because the cover is round, it flips on its axis, the child falls in and the cover slams back in place. There have been 4 incidents of this occurring in the last year alone and as more of these risers are installed, age and get damaged the number is going to go up dramatically in the coming years.

The solutions are simple: get a Fake Rock Home Page to cover it up, or build a small decorative cover (a fake well house or windmill) to protect it. Don't let your child become the next victim.

If you can access a cleanout in the house you can run a snake down the pipe until it hits the tank. That may give you distance but, better, if you have someone with good ears outside you may hear it hitting the baffle in the tank.

Be careful about running a clean out snake into a septic tank, you will knock the "T" off of the affluent entry pipe into the tank.
