Ok. I'm hopping some of you can help me with a very bad drainage issue. It involves a row crop feild, two sides of my yard, and two septic systems. It's probably more than me or anyone in my family can design but maybe there is an easy button solution.
Our house is on a square 5 acre lot almost in the exact center. House is closer to the rear than the front but pretty even from left to right. There is a septic system on the right side and there is an aprox 55 gal drum buried out in the yard quite a ways from the house and what I would imagine the feild lines. This drum is level with the grade of the yard and has two pipes ran to it/from it. There is one "pvc looking" pipe one coming into the drum from the direction of the house or where I believe the feild lines are most likely at and then there is another line that appears to be running from the drum to a culvert at the road front over 100' from the drum. I'll post pics tonight that will help visualize. This section has row crop feild drainage basically swamp it when there is extreme rain. The feild runoff comes into our property at the 1/4 mark of the width or the center of the right side yard and it stands in this section just to the right of what I assume is the septic feild. I don't know who put the system in and have never had to have that side marked for digging but will start searching around before hand.
Right side. The tiny tall spot of grass out in middle of yard is the drum. The valley on the left side which can be seen a little better in the other side picture is similar to this side but not quite as pronounced.
The left side of the house has the worse of the two swamping issues and has a septic system for an addition we added onto the house but the low spot where the feild runoff is on this side is about 15-20 yards to the left of the septic feild bed. There are two lines which were marked last time I dug between the field and the culvert on this side of the house. One is a telephone and the other is fiber for Internet. Should be able to go under both I would imagine with whatever type of drainage system I end up installing.
Left side. The taller green patch of grass right up next to the feild is where the water collects and then continues down the small valley like grade of the yard. This is taken directly over the culvert and that valley is where I plan to trench.
My father in law says we should put in two dry lake systems. Like a semicircular spot dug out that would catch the water as it is coming out of the feild. This would be the easy part. No problem digging and banking two small areas that would theoritically stay dry when is not raining but would gather the water and have corr pipe running from each of them almost in a straight line to each culvert on both sides. But I'm not sure how to run the pipe or if this is the best option. Catching the runoff will be easy this way since its rather predictable. The ground is already higher at the feild than both culverts where I would divert the water to and both sides have somewhat of very very small valley that could follow with the piping trench. The method of laying the pipe and the entrance of the pipe which would be inside the two dry lakes is where I'm not too sure along with the right side septic feild being unknown. Should I put rocks inside the trench with the pipe the entire length or no? I would think that could cause water to rise to the surface since it would not all travel through the pipe this way. Adding some kind of concrete form with a grate at the dry lake entrances might be a good idea or possibly just larger rocks to keep the pipes clear? The small details have me wondering for sure. I have been in construction and farming pretty much all my life but have never had to do anything remotely close to this and didn't pursue my degree in civil engineering/architectural engineering so..........??????
Any and all ideas are more than welcome. I'll probably get the guy who installed the new septic to come out for sure and see what he thinks. He shouldn't charge me much and if remembers putting it in could possibly help me without even coming out.
