Laundry/Septic Drain water

[Harry Palmer]

My neighbor had a similar problem. He added a French drain to the inlet side, filled with large rock, then large gravel. The drain was 12 feet deep by 5 feet wide with three feet of soil on top. This stopped the problem for his three bath 5 person household. :thumbsup: Last year, the person who owns the same place now had to replace the entire system since the leach lines clogged up. He put in a new tank (2000 gal vs. the 1500 gal tank) and a Suez Canal for the drains. The tank dumps into a newly dug pit (25 x 12 x 15 deep) filled with rock and gravel. He lined the entire pit with fabric barrier, which allows liquids to flow through but not dirt, sand, or gravel. From the pit, he has the leach lines extend out 25 feet into the yard. I think he put 150 ft of leach line in place. After he put the heavy rock in, he put in two or three dump truck loads of 3/4 gravel, then he covered everything with about two feet of soil. Based on what the Septic Tank company told him, this system is large enough for a home of 10 bedrooms and twenty people. He told them Good, I won't have any septic problems while the kids are home. :laughing::laughing:

There are only two of us on a fairly large septic system. I always flush a few extra times just to make sure it has enough water.

Why not just stay in the shower 5 mins longer every now and then?

Septic system drain fields are not supposed to be a deep holes in the ground filled with rocks/stones.

The goal is to have a large shallow hole, to maintain separation between the effluent and the ground water. Two foot deep trenches/bed. One foot of 2b stone in trench. Rosin paper or geo-textile fabric on top of stone. One foot of topsoil for cover. Four foot minimum separation between limiting zone and bottom of stone.

Often times conditions do not allow for an in-ground conventional system, and a sand mound is required.

Follow all applicable D.E.P. regulations etc.

The deep hole increases the possibility of contaminating the groundwater.

Just for everyone's info, we ended up redoing the whole leachfield. We used the infiltrator's. Man those things are a great labor saver! They might cost a bit, but I think by the time you include your gravel and conventional piping it is cheaper then an older style. Sorry no pics, it was basically no big deal. The company had it done in a day and I got to sod and smooth. It basically looks normal already. When they put it in, they tore up some of the old field to get to the new location, those leach line were 100 % clogged up. And it was all original. I was under the impression that the leachfield had been replaced because there is newer pvc leaving the tank, but that line just ran to the first distro box. The old system was octagonal clay pipe, and for life of me, it looked like they just butted up to each other in 2' sections. And all of the gravel was clogged up with dirt (no fabric)
If this leachfield lasted 46 years, the new one with these chambers should last much longer!
Thank you all, I have learned so much from TBN, and I would have most likely went with conventional system.
