Looking for advice/ideas on sediment filtration for water coming out of a culvert - feeding a 5/8” water line

[M59]

First thought is that the water must be picking up a lot of debris once it leaves the neighbor's pond before it gets to your pipe. Would your neighbor consider letting you run a pipe directly to his pond?

Second thought is you need a large storage tank like a 275 gallon water tote to collect the water and allow sediment to fall to the bottom of the bank along with a large drain pipe. Run your water line off the top of the tank, but be prepared to periodically drain the sediment from the bottom of the tank.

Kilroy JC,

Please indicate what contaminants are of concern. Is it only silt or silt and small sand or could there be material that floats in the water you are receiving? I had a similar issue but my contaminants were silt and salamanders/ crayfish.

Looking forward to your response.

I set up a tote to catch rain water off from my shed roof about 2014.

At the time the main uses were for a little wash water and water for the drip on my sawmill.
But several times I've REALLY needed water for things like flushing toilets and rinsing down vehicles and it's come in very handy. There are a lot of fittings available and you should be able to easily fit filters to irrigation piping and have a hands off watering system.
Just be sure to filter it VERY WELL and make sure algae (or anything else) doesn't clog it.
It's a royal pain to unclog a long thin pipe.

My concern is any particulate large enough to permanently obstruct a 5/8 ID tube about 700’ long. That would suck.

the bucket primarily fills with fine silt, but the open-cell foam pieces keep it from filling the tube - the foam clogs up, I pull the pieces out, rinse them, rinse the bucket, fill the bucket several times to start suction, stuff the foam back in, re-hang the bucket off the pipe.

I get full flow for a day or two, and then it dwindles over the next 3-5 days until the water stops.

lather rinse repeat

700’ of long thin pipe is exactly what I have!

which is why I am here, seeking assistance from more knowledgeable and experienced people

For a permanent solution, I would build a small concrete dam to form a pond of maybe 500-1000 gallon size, with an irrigation gate to flush it once in a while. Use a well point horizontally as your screened intake, a few inches under the surface.

KilroyJC,

Your water source is the end of the pipe so I suggest the following setup to eliminate anything short of bacteria in the water you are receiving.

2manyrocks' suggestion of a tote is a good one but with the following modifications. Between the water source ( culvert pipe end and the tote) I would place a open topped box with a divider in the middle to separate out the "big" stuff you don't want flowing into your tote. Pic attached. The box is a separator where you place a screen ( of your choice for mesh size ) on top of a divider ( solid wall ) at which you direct the water flow ( best choice is not directly at ( 90 degrees) but at a glancing angle so the screen is self cleaning) and the "filtered water passes thru the screen and the "waste" water flows away carrying debris ( leaves, frogs, chipmunks, sticks, chunks ) that would otherwise end up in your tote. This eliminates the need to clean your tote as frequently and eliminates most of the floating debris that gravity separation will not deal with. Now the tote. How much sediment you want to remove is dependent on whether you intend to pump the "filtered" water and whether or not sediment will damage the pump choice. You want a tote that is a rectangle since fine silt takes longer to sink due to gravity and any currents induced by taking water off the "clean" end of the tote. You want to add the water from the separator box by plumbing a bulkhead fitting into the tote at point halfway up the side wall and take your sediment free ( or near sediment free ) water off the tote at the farthest point away from the entry point. The reason for plumbing your feed water in at the tote's side is the sediment has shorter path to drop out of any possible currents within the tote and the clean water rises to the top. The tote needs to be open to the atmosphere otherwise it will pressurize and stop filling. You could cascade from first tote into second tote and then pump from second tote depending on how much water you need at each time you irrigate. You could also set up a float actuated switch to turn pump off when tote was near empty to prevent pump damage.

I will elaborate if any part is confusing.

Hope this helps.

Something like that is my ultimate goal, but right now I just need an”Good Enuf” solution!

This is exactly the type info I am looking for, and no pumps are needed, as the culvert is approximately 80’ up from where I am sending the water - gravity is a wonderful thing!

basically I will be building a septic tank it looks like. . .

I guess that's one way to describe it. Water source feeding a separator feeding into septic tank feeding into a water storage tank that you pump from.

Sorry the separator is crude hand drawing but a quick way to describe how to have a self cleaning means of mechanically separating the big stuff that you don't want entering your gravity settling tank.

The separator is a box with big holes in the opposite sides to allow waste to flow freely away and a wall between waste side and "filtered" side to prevent cross contamination. The "box" has a bottom so it can be weighted and does not slide away from water being directed at screen.

You want to cascade the water from first tote to second tote to prevent the high currents, induced when withdrawing irrigation water, that may prevent silt from fully dropping out while in first tote. Residence time, when using gravity separation, is critical when working with very fine particles.

The bigger, deeper and more time in your settling reservoir the better. They do make black plastic IBC totes that hold up better in sunlight and prevent algae growth. Stainless steel too.

Or 4” diameter deep well pump lays in our spring inside a 6” pvc sand screen pipe. It’s got hundreds of very thin slits made for well pumps. Places the service well pumps have them. Since our pump is in flowing water it is essentially self cleaning as we pump to a cistern 1/2 mile and 225’ elevation for less than a hour a day. On timer so automatic. Houses have extra filtration.

If you have means to cistern the water at the discharge and periodically pump some back to back flush the filter might work to automate your system?
