Your Private Septic System and the Soil Type on your Property Part Three, the width and length of the infiltration surface are very important design considerations to improve performance and will limit the impact on the receiving evironment. Trenches, beds, and seepage pits (also known as dry wells) are traditionally used geometries. Seepage pits can be effective for wastewater diepersal, but sure don't provide must in the way of treatment, because they extend deep down into the soil profile, where oxygen transfer and treatment is limited and the separation distance to the ground water is reduced.
Width- infiltration surface clogging and the resulting loss of infiltrative capacity are less where the infiltration surface is narrow. This appears to occur because reaeration of the soil below a narrow infiltration surface is more rapid. The dominant pathway for oxygen transport to the subsoil appears to be diffusion through the soil surrounding the infiltration surface. The unsaturated zone below a wide surface quickly, becomes anaerobic because the rates of oxygen diffusion is too low to meet the oxygen demad of the biota and organice on the infiltration surface. This is why trenches will perform better then beds. Trench widths typical range from one to four feet. Narrower trenches are preferred, but the soil conditions and construction keeping the infiltration surface level, the uphill side of the trench bottom just might be excavated into a less suitable soil horizon. The wider trench infiltration surfaces have been very successful in atgrade systems, and mounds probably because the engineered fill material and elevaion above the natural grade promote better reaeration of the fill.

Dale--Not everyone realizes that there are so many details in the construction of a septic system.
Hope you had a wonderfully happy birthday yesterday!
Howdy there Teri
Its a real pleasure to have come by to visit, and to read and write a reply to your comment. On this post, here at my little ole Blogging Homestead, my friend
Most folks don't really know, what really goes in to the planing of a Septic System. But if a home has one, folks sure do need to understand about it.
I sure did have a real fine Birthday yesterday.
Dale I'm late getting here this evening. You are right about the different type soil and what you can do and can not do. Where we live, here in Comal County Texas, it is almost solid rock, David can tell you how hard it is on his equipment. Year's ago when we first moved to Canyon Lake they would use dynamite but they are not allowed to do that anymore. Sometimes it takes David days to dig out some of these areas for the sseptic ystem. Now in some counties where the soil is sandy it is easier digging. Also the size of the property (lot) is very important on how that septic system is placed.
Hi Dale, As C & C said, we have so much solid rock in our area that I am sure installers like David have to work extra hard to get the system in place.
Hi Dale-There is indeed a lot to know about septic systems. You have explained it wonderfully. Happy belated birthday my friend. Hope your day was wonderful. :-)
Howdy there Carl and Ceil, Shirley, Pat
As always, its a real pleasure to have the three of you, stop by to visit and to read and reply to your comments. On any one of the posts, here at my little ole Blogging Homestead, my friends
Carl and Ceil - your never late coming by to visit. We also have almost solid rock in these parts. I sure can understand about it can take a bit of time to dig out some areas.
Shirley - you sure are right about, when an installer is diggen when its mainly rock, they sure do have to work to get the sport ready for a Septic System.
Pat - there sure is a a lot to know when it comes to the Septic System of a home. Just like a lot of other areas of a home, and of commercial properties.
Thank you kindly, I sure did have a real fine day!
Dale just wanted to come by and check things out with your blog and your new signature ending. Catch up with you at the Hang Out.
Pretty extensive stuff that goes into this. Had NO idea! YOU are definitely the ONE for this job!
Diane
Howdy there Carl, Ceil, Diane
Its a pleasure to have the three of you stop by to visit, and to read and repl to the comments that you were so kind to leave. On this post, here at my little ole Blogging Homestead, my friends
Carl - haven't really done anything fancy, did do a little with the font size. Mainly just put what I usual use at the end, into the signauture box. Where I don't have to write each time I post to my blog and the groups. It sure does same time by doing that.
Diane - there sure is a lot to know, when it comes to the Septic System and soil. Thank you for the kind words.
