Eddie, was all the erosion at the culvert caused by water running off the road or was it from water trying to enter/exit the culvert? Are you trying to meter the amount of water going through this culvert?

Hey Jarrett,
I've cut my land and roads to catch as much runoff as I can, and direct it towards my two culverts. I also have a large open ditch that is at the end of my land that carries the bulk of my runoff.
This culvert doesn't catch as much as the other, but the flow was really strong after that rain and the clay wasn't compacted as good as it should have been. If I had some grass growing around the culvert, that would have helped too, but it was just too fresh of dirt.
The exit side damage was very minimal and I almost didn't do anything about it. I looked at it a few times before decideing I had enough sacks on the entrance side.

What I'm concerned about is the pipe being to small which is causing the scouring at the inlet/outlet. Unless you're trying to restrict the amount of water flowing through it, it may be better to increase the size of it. Of course, it may be a little late in the game now. I understand if you wouldn't want to redo what you have done already.

Problem around here is any hole dug in the ground will fill with water. If you are in a dry area the rain will fill the hole faster than it can drain.
We dug our test pit and the rain held off, it came through ok and we have our system in now.
Of course it snowed today and the system is still open waiting for the inspector.

RobJ said:I gotta agree, If I dig a perk test hole and it even thinks about filling with water it's time to look for another spot to put the septic.

Eddie, that's the weirdest way of pouring concrete i've ever seen !!
Pouring concrete turns a messy job as soon as you mix the water with it, so this is a clean and easy way, without the needs for a form

Jarrett,
The pipe is 15 inches inside diameter and I can't imagine the amount of rain it would take for it to be undersized. That's just beyond my ability to comprehend based on owning the land for the last 4 years. There is always the possiblity of the hundred and even the five hundred year storm, but if that happens, I don't thinkg a 24 inch pipe would be enough.
The problem is in the amount of water I'm getting, it's in how quickly it's eroding my dirt around the edge of it. Compcting a culvert isn't too complicated on top, but around the edges of the ends takes more effort than I'm capable of. The dirt is only a few months old since it was placed there and hasn't had anything on it to compact it, or anything growing on it to hold it together. I was hopeful that it would work, but that one storm did more damage than I'm willing to live with.
I have a larger 18 inch culvert between that 15 inch one and my open drainaged ditch. It gets three times the runnoff of that 15 inche one, but it has to work it's way around a bunch of trees. I think that slows down the water and it does't do the same level of damage. After that same storm, there is no erosion on that culvert.
In fact, it's pit in front of it is still there with just about no silt sediment, while the one with the damage filled right up on that storm. That may have soemthing to do with it too. Once the pit fills up, the water hits the culvert at full force.
Ken,
I have mostly clay, so if there is a low area, the water will stay for a week or more. I have puddles that are a few inches deep right now that have been holding water for over a week. Evaporation will be my biggest loss of water.
Renze,
I first saw this done several decades ago by both road crews and State Parks. I guess it was before intelocking retaining wall blocks, because that's all I see now. I've seen the stacked concrete sacks run for hundreds of feet and be dozens of feet tall. I dont know what they did behind the sacks of concrete to stabalize it all together, but on a small scale it's pretty simple.
In time, the paper will rot off the sacks and you'll see the cement. Than in time, that will darken and stain to a nice patina that I like. For me, it's a nice rural look that I enjoy.

I know where there's a retaining wall like that in Denton. I was really surprised when I first saw it, but I didn't have the camera with me and didn't count the number of sacks, but it's one of the taller retaining walls I've seen.

We had a 20 minute storm come through last night that dumped an inch and a half or rain according to my rain guage. A quick, heavy storm like that gives me lots of run off, so I was interested to see what the results were like on the culvert.
First picture shows the amount of silt that ended up in the pit before the culvert. It also shows the road over the culvert and the lake.
Second picture shows the amount of water in the lake as of today. I'm stil about 8 feet down, but that means my deepest point is 4 feet deep!!!!
Third picture shows the shallow end of the lake. It will be 8 feet deep there when full.
Fourth picture shows my open drainage to the lake. This is where the bulk of my watershed will come from. It goes along my Western property line and into my neighbors land. From where it turns uphill, it will have a water coming into it from 20 to 40 acres. It's heavliy wooded, so there's no telling how much water I'll get from it. I'm finding that wooded land doesn't shed near as much water as open pasture does. It's not even close what five acres of grass will shed as compared to 20 acres of woods.

Hey Eddie. Been waiting on the lake report all day. Being a little north and east from you, we knew you were getting some decent rain. Thought maybe it'd be a little more. Rained hard here most of the night. When we shut our systems down in the middle of the night, it looked like most of the rain was north of you.
Nevertheless, that looks like real progress. I could just imagine you trudging through the mud this morning to check it out. Sure looks different than the first time we saw it.

Hey Mike,
Thanks. It's kind of like watching grass grow. Every time it rains, it looks a little different, but just barely. I'm watching the grass grow on the dam too, but that seems to be coming along faster than the water level of the lake. hahaha
