We went to Ontario, Canada to visit some of our customers and this is what they had to say about our Koenders Free Air Windmill Aeration Systems.

“The Koenders system is something I would recommend to friends and neighbours. The main benefit I see from the Koenders windmill system is much better water, clear. It will help suppress weed growth in the pond, its basically maintenance free, you’re utilizing the wind to pump the air down your line and its not costing you anything once you made the initial cost of your windmill. I think the Koenders system, for what you’re getting, you’re getting good value for the money.”
“We put the windmill in one year ago to help with an algae problem we had and it pumps the oxygen in there and it really helped clear the water up. Within one month we could notice a noticeable difference in the clarity of the water. The number one benefit would be keeping the algae down and a second benefit would be oxygen for fish. The Koenders aeration system works very well for us. We’re quite happy with it.”
“The reason why I went to the Koenders aeration system is because we don’t need hydro to operate it and very little maintenance. I like the way it looks. It looks traditional. Structurally it’s simple and it operates fine. It can not over-spin. I would recommend the Koenders aeration system to anybody that is looking for something that is maintenance-free and does a good job. Absolutely.”
“We have an air pump which is manufactured by Koenders and I have it rigged up so that it will pump water into a barrel and then it recycles back into the pond so in the summer time my cattle have instant water and clean fresh water 100% of the time. That was another reason that we put the windmill in because we had to figure out a system to keep the cattle away from the main source of water to keep a fresh supply of water. We do let the windmill run and the air goes into the water 365 days of the year and as of yet I’ve never had a problem. In the winter time the pond will ice over and even if it’s really cold you’ll still see that hole where the air is coming up and keeps it free.”
“We’re very pleased with Koenders windmill. It was well built and we’re very happy with it and we enjoy it so very much. When we’re sitting out here in the summer, people drive by and slow down and the odd one has dropped in and wondered where we got it and we told them it was Koenders. It adds beauty to our place. Many people have commented on how nice it looks. They said our place looks like a park now.”
“We’ve had that windmill behind us for about 10 years now. It does a tremendous job of keeping the ice off in the winter and therefore assures that our fish will survive. One of the nice things about it is once you’ve paid for the windmill there are no operating costs – virtually it works for free. It does a great job of keeping the pond healthy and the fish happy, adding oxygen and degassing the pond.”
“The Koenders windmill aeration system is a fairly simple and beneficial way to achieve aeration for your pond and it gives you a good amount of oxygen into the water which helps prevent algae growth. It’s beneficial if you have any fish in the pond plus it does prevent winterkill for the fish.”
“It’s a fantastic idea to be able to aerate by the wind as opposed to using power. It looks nice to have a windmill on your property. We’re thinking about having our other pond done, dredged and drained out, put a windmill on the other side and use the Koenders system to be able to aerate the pond. Would I recommend it? Definitely!”
“I’ve had these windmills now for 6 or 7 years. I have put no maintenance into them at all. They keep the water open in the winter time and so far I’ve had good luck with the fish that I have in there so it must be putting pretty good oxygen in there. Today is very still. Even though there’s not much breeze now, the windmills are still slowly turning and pumping air into it so I do believe they’re a good thing.”
“I would recommend it to anybody that has a pond. It doesn’t take hydro and it takes very little wind and maintenance-wise I probably spent $25 in 22 years that I’ve had this system so to me it’s the most economical way to go if you’re going to aerate your pond and in the winter time keep it open. The number one benefit is the amount of air that its moving and it keeps the pond open. I need at least ten feet square to keep the predators away from my birds. I’ve had my first one for over twenty years and the following year I bought the second one because I was so happy with it so anybody that wants some information, give me a call.”
Here’s what some of our customers have to say:
I have owned my Koenders Windmill for 17 years and it has been working wonderfully ever since. We currently live in TX and I moved our windmill down with us 4 years ago. It used to aerate a Koi pond that we had, now it is installed on our 3/4 acre cat fish pond. We have about 300 cat fish in this pond.
A few years ago we had a terrible drought down here in Texas, our pond water level dropped from 9 Ft to 3 Ft. All the other pond owners in the area lost their fish, but we didn’t lose any. I credit this to our Koenders Windmill Aeration System.
This windmill has been great, thanks Koenders!

We have been very happy with our windmill. For over 10 years we have been using your windmill to pump water to irrigate our gardens and to aerate our ponds. We had a small issue 5 years ago and did not know what it was so called your support line and they were extremely helpful in guiding us through what was determined to be, a very simple fix, a bolt needed to be tightened up at the compressor. Other than this our windmill has worked maintenance free for all this time.
I am retired now but spent my career constructing bridges and would consider myself quite handy. As a hobby, I rebuild old antique cars so I am, what one would consider, mechanically inclined, Koenders you have built an excellent product that works very well.
Thanks

For over 7 years we have been using a Koenders Windmill to aerate our 1/3rd of an acre Trout Pond.
Before installing our windmill aeration system from Koenders we experienced all sorts of problems with algae, weeds and fish die offs.
I am happy to say that since we installed the windmill we have had no issues with our pond. Our fish are healthy and we have clean pond water. We have not serviced the windmill for all these years, it just keeps on working.
Great product!

My mother bought our windmill way back and it has been in service for over 20 years. It keeps my pond really clean and the fish healthy. We have Bass, Blue Gill, Cat Fish, Crappie and since we installed the windmill aeration system have never had a fish Kill.
In the winter time my kids would skate on our pond so we would simply take the airline off the windmill so that the aeration would not go in. On the winters that they did not skate on the pond we would keep the windmill running all winter long to ensure that we keep the fish healthy. This would also keep the ice of a big majority of the pond so it would attract all sorts of wild life.
We have never done anything to this windmill. It just keeps on working, in all seasons and in all winds, both very low winds and extremely high ones. Quite amazing
Thanks Koenders for a great windmill.

Gentlemen: I recently purchased and installed your windmill aeration system, easy construction and smooth, efficient operation. You make a class product!
Would it be possible to purchase from you a single compressor assembly case only – no pump, no check valve, no pivot post – just the steel case? I have a small generator that I’d like to experiment with. Your case would be ideal for this job. Appreciate hearing from you.
PS. I am amazed at the amount of aeration and rotation of the blades that occur during low wind conditions, A1 Product!!!

We have a 2 acre recreational pond that we have been swimming and fishing in for years. We have perch, bass, blue gill and catfish and I a pleased to say that once installing our Koenders Windmill we have never had a fish kill. In addition, during the hot summer months the pond water is kept clean and algae free thanks to our windmill aeration system.
We installed our windmill over 15 years ago and the only maintenance that we have done is replace the diaphragm and check valves in the compressor 8 yrs ago. Its like clock work, for less than $ 50 in maintenance every 8 yrs I have a clean pond and healthy fish. We do not use Pond chemicals for we do not believe in putting toxic chemicals into the water that we fish and swim in. I am however, interested in your Natures Pond Conditioner. I understand that this is a Food Grade Pond Dye and beneficial bacteria and enzymes that help ponds maintain a healthy eco-system. Giving our pond water extra help to fight off pollutants in the area is viewed as a good addition to our pond and its inhabitants.
Thanks again and look forward to receiving the information on natures pond conditioner.

Thank you all for the great windmill aeration product that you manufacture. and support I have owned my Koenders Windmill aeration system for over 8 years and have not done one thing to it.
The windmill looks great and is a perfect addition to our back yard. We have a 3/4 acre fish pond (bass, catfish and crappy) surrounded by rocks and trees. This unit really adds to the beauty of the yard.
I would not just buy the windmill for yard art, it has to work too and it certainly does. This windmill aeration system keeps my fish healthy and alive during all seasons. It also keeps our pond water quality good and clean. This is important for we use the pond water for fishing, swimming and household use.
Thanks again for a reliable and durable product.

Koenders,
Wanted to let you know that your product has been great. For the last 12 years I have used it to aerate my 3 acre Fish Pond. Ever since installing this windmill I have never had a Fish Die OFF. Up until then every year before that we would have a fish Kill.
We recently had an issue with a Dealer who does not sell your product who sold us a Maintenance Repair KIt. They never told us that it was not a Koenders Windmill product. It must have been a knock off. In any case this kit only lasted 8 months. I would caution Koenders customers to make sure that they are buying Koenders original parts so that they are not inconvenienced like we have been.
All the best!!

Koenders Windmills,
Wanted to thank you for a product that has been maintenance free for the past 10 years. I always appreciate a product that lives up to its promise and Koenders Windmills has even exceeded our expectations. Before installing our windmill aeration system we had experienced fish kills during the winter months. Our Koenders Windmill Aeration system has kept our pond open and fish healthy during the winter months and we have never had a fish kill since.
We have a 1.5 Acre Fish pond and our Koenders 16 FT tower unit has done a wonderful job. Thanks again for a great product!

Koenders Windmills,
It has been so long ago that we installed our Koenders Windmill Aeration System that I forget what year it was, atleast 12-15 years ago. In this time, we have not touched this windmill. That is right, no maintenance on it at all. This unit has been working flawlessly until this week. I find out that all I need is a maintenance repair kit for less than $ 50 to get it back up and running. AMAZING!!!
What got us to install this windmill in the first place is a FISH KILL that we had one winter in our 1 acre sized fish pond. After installing this windmill aeration system we have never again experience a fish kill. Our mainly Bass, Blue Gill fish pond have stayed healthy and seem to grow very fast.
We look forward to trying your Natures Pond Conditioner next Spring.
Thanks
Koenders Windmills
We have been a customer of yours for over 10 yrs with two Koenders windmill aeration systems that aerate each of our trout ponds.
Before installing Koenders Windmill aeration systems I was experiencing regular Fish Kills. I am happy to say that ever since our windmills have been in operation that we no longer have fish kills at our ponds.
Thay have worked extremely well and for the last 10 yrs we have not done a thing to them to maintain the units. When are windmills are turning, which is at very low winds, they put sufficient air in the ponds to keep our trout healthy and alive.
Thanks for a great product.
Koenders Windmills
Thanks for a great product – we have not had a minutes trouble with this windmill since installing it over 15 years ago. It keeps our fish healthy and during this time we have never had a fish kill.
We use our windmill 365 days a year and it works in the harsh winters and the boiling hot summers. The windmill also helps keep the weeds and algae out of the pond which is another great benefit to your windmill aeration system. I cant imagine how much I would have spent on electricity over all these years if I would have installed an electric aerator.
Thanks again.
Koenders Windmills,
Just a quick note to let you know that I installed my windmill aeration system over 10 yrs ago and am only now needing to replace the diaphragm kit ($ 50).
You tell customers that every 5-7 years you will perform this maintenance so once again you have exceeded our expectations. We have catfish 2.5 Ft long and bass that are over 2 FT long so ensuring that we never have a fish kill is important to us.
Your windmill has made sure that are fish stay healthy and pond remains
clean.
Thanks

I have had one of your Koenders Free Air windmills installed on our 2 acre fish Pond for over 8 years. Since we have installed this windmill aeration system I am pleased to say that we have never had one fish die.
The windmill has been reliable and efficient. What a great product.
Thanks
Dear Koenders
I have had my Koenders Electric Aerator for over 10 yrs and this is only the 2nd time that I have had to replace my maintenance kit ($ 49.95 Kit).
This unit is a work horse and hardly consumes any energy at all. I use this full time on my pond and it keeps it open in the winter months so that my pond water stays healthy and my fish remain alive.
We are just thrilled with our investment in Koenders EL2. You guys are the champs!!! If everything I bought could last like a Koenders I would be a very happy customer.
Thanks
Hey Yall! Just wanted to say that the windmill is up and the pond is perculating right along. I’ve enjoyed the easy assembly, by myself, but the biggest thrill was standing it up and watchin it spin! A great product for the money, and a great staff backing it up. Check out the pictures of my 20 footer, done “TEXAS” style! Another happy customer!
Koenders Windmills,
From One of YOUR FIRST CUSTOMERS – 23 years AGO!!!
We bought our Windmill Aeration System in 1988 and must be one of your first customers. Today I ordered another Koenders Windmill for my neighbor because he has been so impressed with how mine has been working for all these years.
Our windmill was used 23 years ago to aerate our dugout to avoid pond stagnation and algae growth as we needed to ensure our cattle drank from a healthy water source. It did a fabulous job of that for years. We also used the pond to hold trout. Before installing our windmill we would regularly have fish kills. We have never had a trout fish kill since installing our Koenders Windmill and it is still used to this day to keep our fish healthy and alive.
Our windmill keeps going and going! Never had an issue or any maintenance
on it.
Thanks again for a great product!!
Regards,
Koenders,
We have owned our windmill aeration system for 14 years and are amazed by the incredible job it is doing in keeping our pond healthy and clean. Our Koenders Windmill has removed and kept out 99% of the weeds and algae in our pond.
The other great thing about this windmill is it has works both in low winds and in high without any problems – we have not done any maintenance or repair for this long. The only thing I have done is grease the pivot
tube every few years to facilitate it turning in and out of the wind. Up until now this is the only thing I have done. Now I will replace the diaphragm with the maintenance kit that I have recently ordered which I fully expected to do years ago.
Ou grand kids love this pond – they fish in it all the time. Even during the winter our windmill pumps air into the pond – it helps keep the fish healthy, we have never had a fish kill since installing the windmill.
Thanks again for a great product!!
Koenders Windmills a Snap to Assemble
We recently got the first of two windmills up and running. The instructions were so detailed, that assembly was a snap. It reminded me of my days playing with an erector set when I was a kid. The wind mill works great and the fish have never been happier. Also, we happened to buy a Weather Channel remote weather station and mounted the anemometer on the base. It appears that somewhere around 1.2 to 1.5 MPH the fan starts turning. That seems pretty efficient. I’m looking forward to getting our second one in service.
Here’s photo of the final assembly phase and completed windmill. We loved the “Thin Ice” decal too.
Koender Windmills,
Thanks to your detailed instruction manual and assembly guide for our Koenders Windmill Aeration System the installation went smooth and easy. I found that by following it step-by-step was the best way to go and it all started making sense and coming together early in the assembly phase. Our windmill is now up and running and works great. Not bad for a 60 year old women. By the way the pivot pairs made it really easy to assemble as well.
Many Thanks.
“Here are two pictures of the windmills. The aeration really works – energy for free. We love it!”
“After assembling the windmill in our shop (1 guy about 8 hours), we took it to the site and anchored the pivot points in high-strength concrete footings. After setting overnight, we tipped it upright and anchored the third stake. Hooking up the airlines was a snap, and we now (as soon as we receive more air line) have 3 diffusers in 3 different locations throughout the pond. The building behind the windmill is our pump house which feeds the irrigations system. Clean, algae-free water for irrigating our golf course is crucial, and the main reason we chose to purchase a Koenders windmill aerator. I will send you a few photos later today. Thanks for all your help!”
“As an aquaculture consultant, I try to minimize fish diseases and parasites and maximize fish production. Three installed Koenders aeration windmills help. In North Florida your windmills economically improve water quality by aeration, reducing sedimentation, algae control, combating stratification and improving water temperature control. This resulting improved water quality lets North Florida fish farmers maximize stocking capacity and disease and parasite control”.
“Attached is a photo of my new Koenders pond aeration windmill. I should add that I had great fun assembling it in my garage over the (cold) winter; the instructions that arrived with the parts were very useful and your service in response to telephone questions very friendly, prompt and professional.”
“We purchased one of your windmills to aerate our pond in South Florida last year and are amazed at how clean the water is. But more importantly, it survived Hurricanes Frances and Jeanne. We lost around 7 pine trees, but your windmill is still standing and working just fine. Thank you for the great product.”
“I could not be happier with the results, in 2 months you can see a marked improvement in the water quality. We have already had 2 ducks & a family of water fowl take up residence … The mill was easy to assemble & erect & has performed perfectly … A happy customer “
“I have owned a Koenders Windmill for nine years. I have had to replace the front bearing once. I contacted Koenders to see if there was anything else I should do; they told me that a heavier crankshaft and bearing update was available. I was very pleased that I could improve my windmill without having to replace the whole machine. I also replaced the original diaphragm, even though it showed little wear. My windmill runs like a new machine. Thank you for a machine well built.”
Click for Larger Image“Just thought I’d send you a picture of how the Koenders Windmill Aeration System has kept out pond open this winter.”
“I purchased two Koenders wind aerators in the summer of 2002, for my 4 acre lake. I could not be more pleased. The units are completely maintenance-free and extremely reliable.”
“On July 18, 2000 we installed our first Koenders Free Air Windmill on the shoreline of our 20 acre lake at 8850′ altitude. This windmill worked with such efficiency that we installed another windmill the next year. The Windmills work year round and operate efficiently at low wind speed. They have exceeded our expectations; they are efficient and require very little maintenance.”
“United Farmers of Alberta Cooperative has been dealing with Koenders Windmills for many years and have sold their Windmills throughout the entire province of Alberta.
We have had great success with their product and have been very pleased with both the High Quality and Support provided by Koenders.”
“I am so pleased with my last purchase of one of your windmills. It has performed beyond all my expectations. I like it so much that I ordered another one.”
“2 years and really like it. I want to let you know how pleased I am that, for the last 2 years I’ve had one of your windmills aerating my 1 1/2 acre lake. Ours is one of the clearest and most weed-free lakes in our area. The Dealer I purchased it from has been great to work with.”
“The water quality improved quickly…within 2 weeks of the installation”
Click for Larger Image“I am sure my fish could not have survived this winter had it not been for my Koender’s windmill. The first picture was taken the week before Christmas. That was the last time I saw it completely free of ice. Since then I have had one partial melt around the edges which lasted for a couple of days but it has also been cold enough to freeze it over completely.
Click for Larger ImageEven then, you could still see where the windmill was working, aerating the water under the ice.
Today, after two days of unseasonably warm weather, we are back in the deep freeze… but my Koender’s windmill just keeps working (notice the open water near the center of the pond!) … churning in fresh air deep under water.
Click for Larger ImageAs I was riding my Harley around Valley City last summer, I could not help but notice the number of windmills appearing recently by ponds large and small. I cannot imagine anyone in Ohio who has a stocked pond ever being without such a device again. I know I will never be. It pays for itself with every restocking it saves! Thanks again for helping me acquire such an essential and functional product. It gave me a great sense of satisfaction and accomplishment to assemble and set it up myself. What a great environmental statement!”
“Hi Koenders. Here is a formula for success.
Koenders Windmill + Wind = Clear Water
We installed a windmill on our pond bank to aerate the water for better fish and livestock usage. We have a frost proof tank, which is gravity fed with a float valve below the pond. We noticed that several months after we installed the windmill the water was so clear that we could see the bottom of the tank. The whole pond is much clearer but I don’t understand fish talk to hear their comments.”
Koenders,
Wanted to let you know that your product has been great. For the last 12 years I have used it to aerate my 3 acre Fish Pond. Ever since installing this windmill I have never had a Fish Die OFF. Up until then every year before that we would have a fish Kill.
We recently had an issue with a Dealer who does not sell your product who sold us a Maintenance Repair KIt. They never told us that it was not a Koenders Windmill product.

I would caution Koenders customers to make sure that they are buying Koenders original parts so that they are not inconvenienced like we have been.

Koenders Windmills Organization,
Our Koenders windmill has been aerating our 2.5 acre Fish Pond for between 12-15 years. It is 22 FT deep and so our Cat Fish thrive in this environment, some of them are upto 4.5 FT long. In the freezing months its especially important to have the aeration going for it keeps the pond open and gives the fish the oxygen they need to stay healthy during those cold winter months. Since we installed our windmill aeration system we have never had a fish kill.
The other benefit we have noticed from our windmill aeration system is the clarity and clean look of the water during the rest of the year. We do weddings by our pond and people love taking pictures by it with the windmill in the distant background. This system has been working with no problems at all until just recently when we had to change out the diaphragm and check valves. Your company recommends every 5-7 years to change this out, well we have not had to do it for double that time.
These windmill aeraion systems work fantastic.
Thanks and Happy Holidays!
Hi Terry & Gina, Hope your thanksgiving went well. I thought I would drop a note to let you know how clean & clear my 1/4 acre pond is. Although I had no assistance building my tower & turbine, the day to haul it out to my pasture 140ft from my pond everyone showed up to help after getting the word out. During the lift up i assigned one person to touch up the paint where the tower was resting on a sawhorse for the perfect paint job.
Since I installed the Koenders Windmill I have not had one concern over the way it operates & have watched the water clean itself up as my pics reveal. Pardon my water level as it’s 3 ft low due to a very long drought this year. My fish are very active also. Thanks again for a great product.

When we were building our house over 9 years ago we needed to elevate the ground where the home would stand in order to comply with the county regulations. In order to do this we decided to dig out a 1/2 acre pond and use the soil to build up our home’s elevation. When we did this we wanted to make sure that the pond remained clean and maintenance FREE. So 9 yrs ago we installed our Koenders Windmill Aeration System. Living in south Florida we get both hurricanes and hot weather so the aeration equipment must be sturdy, durable and efficient. Your product has proved that.
We have a 1/2 acre fish pond – the fish are made up of whatever the birds drop in the water , bass and brim fish primarily. The windmill keeps our fish healthy and more importantly the pond water crystal clear. We have the best looking pond in the neighborhood and the Koenders windmill aeration system is the reason! I am sure of this because just 400 FT away is my neighbor’s pond who has the same water source, and, his pond is dirty and cloudy.
In 2005 we suffered the hit of 3 hurricanes in one year. The Koenders Windmill survived them all!!! Very Impressive!!!
Thanks for living up to your promises!!

Click for Larger Image I first bought my 24 foot Koenders aeration Windmill in September of 2012 to hopefully clear up my spring fed pond, and it did! Assembly of the windmill was pretty simple, took some time but directions were very helpful. I was worried about the pond freezing over this winter when temps got below 10 degrees, but as long as the wind was blowing it was aerating..
If you put it together as per the directions, you can’t even hear the turbine moving. I am very happy with it and decided to buy a second one. I’m very excited to get it in. I ordered it today and it should be here within two days.
Terry, who is in charge of the US division at Koenders Windmills was very helpful. Needless to say I highly recommend a Koenders windmill to anyone looking to aerate a pond, lower your electric bill or use it for decoration. Great windmill.
Thanks again Koenders!

We have been using your windmills to aerate our 11 Acre Fish and Irrigation Pond for over 7 years. We have several of your Koenders Windmill aeration systems on the pond and it has served to keep the water algae and weed free. This assists us in irrigating our corn, hay and alfalfa fields by ensuring the irrigation pumps do not get clogged up. Aerating the pond has also kept our fish alive and healthy. The pond at our University is also a conservation area and is open to the public for fishing.
Your windmills have worked extremely well to serve our purposes and they have been maintenance FREE.
All the best!

Koenders Water Solutions,
We have been using your Natures Pond Conditioner for the last 4 years and it has been working extremely well in controlling the algae and weeds, especially in the hot summer months. We live in Vermont and have a 1/4 acre recreational fish pond which we also swim in during the hot weather.
The idea of using toxic chemicals to treat algae and weeds did not appeal to us and so we selected Natures Pond Conditioner as an alternative. We also use one of your Koenders Windmill Aeration systems that has been very reliable.
During the winter months of January and February we skate on our pond so we take the airline off the windmill and for those two months we do not aerate our pond. Adding Natures Pond Conditioner in the Spring and Summer has helped restore our water back to normal and combined with the windmill aeration has been an excellent solution to keep our water healthy and clean in a sustainable way.
We appreciate your comittment to the environment and providing customers with an alternative choice to toxic chemical treatments.

Koenders Water Solutions,
We have been using your windmill aeration system on our 3 acre Fish Pond for over 16 years. It may be hard to believe but we have never had an issue with the windmill. Never taken it down for any maintenance, never even done any maintenance on it.
The windmill aeration has done a wonderful job of circulating the water and keeping the pond open in the winter months. This windmill has helped keep the fish healthy and pond water clean.
Thanks Koenders, we are real pleased with your product,

Koenders Water Solutions,
As per our conversation today, I have owned my Koenders windmill aeration system since 2002. It has worked extremely well in keeping the water moving and the weeds down. In the past, we had a lot of fish in the water but all the animals ate them. The aeration did such a good job of keeping them healthy that the fish were a great meal source for everyone but us. The Blue Herons, Racoons, Beavers, Muskrats all took part in depleting our fish population.
We now use our pond as a swimming hole during hot summer months. When we bought our windmill over 11 years ago there were none of these units around. Now, anyone in the area who has a pond also has a windmill, 50-100 of them in the region.
A few of the neighbors have installed other brands but they clearly do not work as well as the Koenders Windmill which is what almost all of the pond owners have.
Thanks Again, we will keep on recommended your product, its the best!!!

Koenders Water Solutions,
We purchased a Koenders Electric Aerator – the EL2 unit over 10 years ago and it has been running 24/7 ever since. The only maintenance we have ever had to do is replace the diaphragm in it once. It keeps our pond/dugout water sparkling clear and is the water that we use for our cattle to drink from. I sincerely wish more products were as well built and as long lasting as these Koenders EL2 aerators.

Since 1993 the City of Prineville has operated the Meadow Lakes Golf Course. This course is part of the City’s wastewater treatment plant and is used to dispose of treated effluent. The course contains 10 large ponds of treated effluent, providing a water hazard on all 18 holes. As the ponds contain treated wastewater in such close proximity to the public, the Department of Environmental Quality would not allow for water features to be used that would spray or aerate the water. Over the course of the last 18 years, the organic loading in the ponds has increased significantly.
The ponds were originally designed is such a way that the naturally occurring bacteria would utilize dissolved oxygen to decompose this organic material. Unfortunately, the bacteria were unable to keep up with the organic loading and issues arose. At certain times of the year, the level of dissolved oxygen in the pond would reach zero and the bacteria would begin to use sulfate as an oxygen source for respiration. By consuming the oxygen atom from the sulfate molecule, hydrogen sulfide was produced and the golf course was overwhelmed with the classic “rotten egg” odors.
The City recognized that the ponds needed to be aerated to prohibit the production of hydrogen sulfide and to clarify the water. However, there was no power source near the ponds to provide aeration and trenching miles of power lines through the turf and irrigation systems was not possible. The City teamed with Koenders windmills on a solution. By placing 5 separate windmill systems on various ponds, the City has cost effectively solved the problem. The windmills have now been working for 1.5 years and the hydrogen sulfide smell has not been an issue once. Also, water quality is slowly improving. Overall, Koenders Windmills have been a great, cost effective solution for the City of Prineville.
Below is a copy of an article regarding the windmills posted by the local paper.

Koenders Windmills,
We have been using your windmill to aerate our fish pond for over 10 years. The year before purchasing the Koenders Windmill we had a large fish kill, never happened since we installed our windmill aeration system. It works very well in keeping the pond water open in the winter and the water clean in the summer.
Now we have a healthy population of large mouth bass in the pond and the birds certainly seem to like it. We get ducks flying in all the time and snacking on the fish, fun to watch. Just decided to increase the height of my tower from a 16 FT tower to a 20 FT tower. I like the idea of the hinges as well, so that we can tilt the windmill up and down. After 10 years we have not had to do any maintenance on this windmill what so ever, so I am expecting in the next couple of years that we may have to do something, even if it is just changing out the diaphragm kit. The hinges will make it easier to do that.
All the best,
Dirk Emde

We bought our Koenders Windmill in 1990 and replaced the first diaphragm around 10 years later. Here it is 2013 and I am just replacing it again. Other than greasing the tower top every year it has needed nothing else.
We have bass, bluegill and perch in our pond and the windmill keeps the water in real good shape and our fish healthy. Our pond gets used for picnics and church gatherings, so your Windmill is seen by many. Great product.

Over 12 years ago we installed a Koenders Windmill to pump air into our 3/4 acre Brim and Bass Pond. The only issue we’ve ever had with our pond was when we didn’t maintain it with our windmill aeration system. Since installing the windmill we have had no issues with either it or the pond. Louisiana is not known for high winds, however, this windmill has worked so well in low winds that it has been an ideal solution to keep our fish healthy and our pond clean. We like to keep our pond looking nice for it is located right by our house. We are looking forward to trying the Natures Pond Conditioner – the other pond dyes that we have tried make our water look too fake.
