about 1,000 feet away from electric,3/4 acre pond. What type of line and cost? How deep to bury? Any other info or links greatly appreciated.

I talked to an electrician about running wire about this same distance. He didn’t want to do it, because of the distance. He suggested I talk to our local electrical coop. I did, and their recommendation was to run another line from the pole by our barn and have it on a separate meter. They were recommending a pretty heavy wire. I don’t remember what it was, but the cost was in the multiple thousands of dollars. If I remember correctly it was considerably higher than the cost of the aeration system.
Hope you find a better solution, as I’d still like to do it, if feasible.


9 yr old pond, 1 ac, 15' deep.
RES, YP, GS, FHM (no longer), HBG (going away), SMB, and HSB (only one seen in 5 yrs) Restocked HSB (2020) Have seen one of these.
I think that's about all I should put in my little pond.

bugeye,

Do you want electricity at the pond, or aeration at the pond?

If aeration, it is generally much cheaper to run air line compared to electric wire. Also, if it gets cut by somebody working your ground, there is no risk of harm.

If electricity, you need to calculate your expected draw from all of the equipment that might be operating at the same time. Use a calculator (or a good electrician) to determine the voltage drop over your distance for that draw, and then use the smallest (cheapest) wire that will have an acceptably small voltage drop over that distance.

You may be able to hire an electrician to do the connection where you come off of your existing power and to do the connection and outlets at the pond. He could do the calculations for you and tell you exactly which wire to use for code, and how to leave it for his connections.

Will your line run through easy ground or difficult ground? (Rocks, tree roots, etc.) If easy, you could probably rent a riding trencher and do it yourself. The rental for a Ditch Witch RT45 is $300/day in my area.

1" ID low pressure black poly line. Depth just has to be deeper than the ground will be worked. Try to use the minimal amount of connectors underground as the plastic like shrinks and expands with the temp change. Cost is a location thing, find a landscaper that puts in irrigation systems and they can get in the ground pretty cheaply without tearing up the ground if they have a vibratory slitter. I've had them slit/pull 1" 900 feet with no issues, and 1 1/4" line over 1/4 mile.

Pex B works well, just remember to get stainless crimps and connectors.
The 1" as suggested is good for that length, and keep it out of the sunlight. UV rays over time will wear on it.

I was about to start a similar thread. Just got my new aerator set up and I'm running 600 ft of air hose to my pond. Currently just sitting on top of the ground but planning on burying it soon. I've run regular 3/8 in 300 psi air hose I bought off amazon. I'm wondering about burying it. Do most people run it inside of conduit or PEX for protection? Also thought about just pouring sand inside of the trench to protect from from roots and rocks before back filling it.

Consider how much air you need to push through that 3/8 line and how much PSI it takes on one end to create the proper PSI on the other. Remember at depth there is a certain amount of extra water pressure the pump has to overcome to produce the proper air plume. I don't know how much more resistance is in a 3/8 line but it might mean the pump has to work harder or be upsized.

I'm sorry to say this, but a customer had 3/8" line run to his diffusers from his compressor. He fought freezing air line in the winter, and a very little air flow out of the diffusers. After the 2nd time he had to dig up sections to find where the leak was, he gave up and had us run 1" to the pond. The psi dropped considerably, air flow increased, and he didn't have any more issues of the line freezing during the winter. One pond was 600' away, the other was 900'.

My advice is to ditch the 3/8" line now before you put any more $$ into it and go with a bigger diameter line. We used low pressure black poly line.

I just saw online where 660' was around $450. Look at the drip irrigation sites. You are never going to see more than 20 psi in the system.

Esshup, got a link to the low pressure line you're talking about? Sounds like a good low cost option.

Interesting. Thanks for the feedback. My aerator came with 3/8 in hose so I just added to it. Is it usually thicker hose that most people run, or just for longer distances you increase the diameter? Definitely don't want to be fighting underground leaks. As of now I am more than impressed with the output from my diffuser, it's got my little pond looking like a wave pool.

3/8" diameter airline seems pretty typical for the fairly short runs inside ponds. The longer the run, the bigger diameter pipe you need to keep drag./friction/resistance reasonable, and the flow rate high enough with typical aeration system compressor pressure. The situation is directly analogous to the need to use larger diameter wire for long distance electricity transmission to reduce the resistance and hence line loss (Mechanical Engineers and Electrical Engineers even use the same symbols for schematic diagrams of pneumatic/hydraulic and electrical systems - or at lease they did 40 years ago when I was in school).

That makes sense, thanks. Assuming no leaks develop in the line over time, if the output is satisfactory now at the diffuser is there reason to believe there would be output issues in the future?

Maybe not output issues, but the increased back pressure will make the compressor wear out faster. How many PSI is the system operating at now?

This stuff: 1" Irrigation low pressure tubing

You can get it from a local plumbing contractor supply house. That's where I get mine. NOT a big box store, a plumbing or irrigation supply house.

Better price here but no free shipping. Worth checking out though. Might save you some $$$.

660' for $147

Yep! Keep searching for the lowest price. I just threw that link up because it was the first one I found.
