The next project this spring will be adding drainage between my home and flower beds as well as to low spots in the lawn.

The house we bought has a slightly negative sloped lawn, from the middle of the front lawn to the house. Water pools along the house between the raised beds and the home along with the lawn (grass) near the beds. I sodded with centipede areas along the beds last fall and it’s drowning out the grass. I’m convinced it’s a drainage issue. I have 18” of rocks between the beds and home, no drainage or gutters on the home.

Questions:
Do you have any recommended resources for lawn drainage?
Can I use just the black corrugated pipe to run drainage between catch basins or will it overtime fill with dirt and clog?
Do I have to do a French style drain, with rocks and the works(seems to be a PIA)?
I like the idea of subsurface drainage the corrugated pipe offers vs. pvc pipe with catch basins as the pvc pipe does not have holes allowing subsurface water to drain, it would strictly be the basins draining the water.
Can this be done by one man (myself) or is it realistically too much to pull off? It’ll be 80-100ft of trenching if I run it to the road.
TIA

Looking forward to this thread. My other project I’m working on. I got the catch basins and drainage cleaned out yesterday but there are still some concern in my lawn.

And yes, black pipe will clog up. Lawn man will clean them out for you for about $50.

Would it be less likely to clog up if you wrap it with gravel and a drainage fabric?

No way to correct the slope if you hauled dirt? Seems like an easier way than installing drains & it would look better overall.

I think I would need to haul off dirt, opposed to adding more. Picture frontage road and then halfway into the lawn a hill with one slope pitched down towards the home stopping water from draining to the road. (exaggerated but paints a picture)

Having done some DYI drainage projects myself at my home, use solid thin wall sewer pipe as opposed to corrugated drainage pipe - corrugated pipe clogs over time in my experience, no issues with the sewer pipe and it’s really not expensive. Use catch basins. Pipe with holes facing downward are to drain ground water that rises to the surface in reasonably porous soils - if your yard is heavy clay soil as mine is ground water is not your issue - you need to remove accumulated surface water in low areas.

You can rent a 4 inch or 6 inch trencher to dig a trench a 100 ft to the road - I did. Helps to have a friend assist. We split the cost of a 4 hour rental, we did both his and my yard in that 4 hours. Of course you need to mark underground lines and hand dig around those, and you need to insure you have have sufficient gravity/slope fall to the street to insure drainage.

You can always get an estimate of having a contractor do it, and estimate the cost of DYI, and see if the savings is worth it to you.

I recently did a DIY drainage in my yard after I was quoted $1200 for a contractor to put in about 130' of drainage.

Put in three of the 6" round ADS basins and used the thin walled 4" PVC from Lowe's that was about $4 for a 10' stick. If you use solid pipe rather than the corrugated if cuts the required slope in half.

Do yourself a favor and get the 6" trencher, I rented a 4" trencher and that thing did not cut a 4" trench. Spent two days getting it knocked out due to the amount of hand digging that I had to do.

At the end of the day it came out good, only spent about $250-$300 on materials and works as intended.

Rob P - did you run the pipe to a ditch or did you put a pop-up spout in your yard?
I’m thinking about the later now that I read up on it.

I've run 4 4" pipes with drains throughout my yard. One in the front that carries water in the flowerbeds/front porch out to the front ditch.

3 spaced out in my backyard that daylight to the rear ditch behind my fence. All with a shovel and an electric mantis tiller. At least 400' total. Two of them, I stopped short and did an emitter in the yard. Those sucked, even with a natural slope. Clogged with grass clippings and leaves, left a streak of debris and death near them.

It's all fairly simple if you can work a shovel, but don't stop short. Go all the way to the ditch.

I am fortunate to have a large ditch running behind my back fence which separates my property from the neighbor beyond, so I just ran the pipe out into the ditch.

I am thinking that is the main thing that could jam someone up if that option wasn't available.

I got a few quotes for this type project in the BR area, and they were $14-$16 per linear foot.

Not all corrugated pipe is perforated. If tree roots are not a problem and will never be a problem, and you will not be crossing with a vehicle, nothing wrong with installing corrugated.

I’ve recently completely done the drainage on my house on a tough Ozark hill. All downspouts to PVC buried, plus catch basins running to ravine in problematic areas.

Here, I think you could do a catch basin or two, running the load either to the street or a dry well in the yard, whichever is easier.

I’d use 3” PVC since it’s just ground flow (less digging involved). If you run to street, what’s your estimated maximum depth needed to hit proper slope? That’s the key question.
