The Koenders approach
Aerate. Condition. Maintain.
Oxygen is the foundation of healthy water. Pair bottom-up aeration with natural conditioning and simple seasonal maintenance for clear, balanced water at any scale.
- Step 1
Aerate
Windmill, solar or electric systems move and oxygenate the water, the core of any healthy pond or lagoon.
- Step 2
Condition
Beneficial bacteria digest the nutrients and organics that drive algae, muck and odour.
- Step 3
Maintain
Freeze-control, parts and simple seasonal care keep your system performing for years.

Real stories
Real people. Real results.
Farmers, ranchers and operators share how Koenders aeration keeps their water open and clear.
Why Koenders
Engineered for the real world
Built for remote sites, big water and demanding operators, with more than three decades of aeration know-how behind every system.
No power line required
Our windmill aeration runs on wind alone, so remote dugouts and off-grid sites get oxygen without a power line or fuel.
Windmill, solar or electric
Match the power source to your site, from fully off-grid to grid-tied, without changing the way the water is treated.
Scales with you
The same bottom-up aeration works from a small pond to a large municipal wastewater lagoon.
Made in Canada
Designed and manufactured in Saskatchewan, with parts and support you can rely on.
Windmill, solar and electric aeration
Oxygen for every pond, on or off the grid
Koenders got its start in 1988 building wind-powered aeration for farm dugouts. Today that same rugged, low-operating-cost engineering carries across our full lineup of windmill, solar and electric systems, each matched to your pond size and power source, so water stays healthy on farms, acreages and remote sites across the continent.
From operators
Trusted on farms, courses and municipal water
“Our Koenders windmill has aerated this pond for over 20 years. Even after a long, cold winter there was no fish kill, and we still catch beautiful trout.”
“The before and after says it all — clear water on a 10-acre irrigation pond from a Koenders windmill and Nature's Pond Conditioner.”
“We've run a Koenders windmill for 10+ years. Our pond looked so good we held a wedding right next to it.”
“We saw a drastic difference in 7 weeks. The picture says it all — couldn’t be happier.”
“Nature's Pond Conditioner and our Koenders windmill are a great combination — clean, clear water and healthy, large rainbow trout.”
“Thanks to Koenders aeration and Nature's Pond Conditioner, we're able to enjoy ice fishing again this winter.”
“Great quality. My best friend and I put this windmill up in our retirement — no problems with parts, and it keeps the muck and algae down.”
