Government Facts on Pond Aeration Using Windmills

Citizens Concerned about the Quality of Municipal Pond Water

Aug 14, 2013 – Listed below is an email to Pond Owner Magazine from a concerned citizen about the health of their Municipal Ponds. What we have done is published our answer along with links to government studies that prove pond aeration works.

There are several forms of pond aeration – clearly the most effective is Bottom Up Aeration which aerates water from the bottom of the pond to the top.

One of the most ineffective methods of pond aeration are fountains. They are both costly to operate and only provide aerating to the top few feet of the pond’s surface.

Koenders Uni-Pole One of the most effective methods of aeration are windmills. Koenders Windmills has recently developed a 25 FT Uni-Pole Windmill aeration System especially for Municipal Ponds. The uni-pole prevents people and animals from climbing up the windmill and it just below the 30 FT height restriction some times imposed for windmills by regional by-laws. Koenders Windmills have been building windmill aeration systems for 20 years and helps do away with the use of chemicals to treat water which is regarded as a short term fix to any pond algae problem. The cost of these units are a fraction of what the costs are of fountains and for under $5,000 both your ponds could be aerate on an ongoing basis with no costs of operation. Windmills aeration systems self operate and a practically maintenance free. They run of the free wind and are built to last decades.

Here are a few government studies about the positive effects of pond aeration for you to present to your local government – also have your local government read the other articles that are posted here on Pond Owner.

Hello Pond Owner,

Our community has two large ponds in our central park.

For years, the Parks Department has been running fountain aerators with a high GPM to supply extra oxygen to the ponds to aid in the natural cleanup process.

However, because of improper maintenance, those aerators have repeatedly broken down, and at the end of last summer, all of them died and are no longer functional.

A small committee of concerned citizens is asking the city to replace those fountain aerators with new, high GPM fountain aerators because we are concerned about the health of those ponds. When the aerators have broken down in the past, there was noticeable odor and algae buildup along the shore. We also want the city to allow a private company to maintain the new aerators (install, removal, cleaning, heated storage, and maintain the seals and oil) so they are taken care of properly.

The city has decided to remove the funding for new aerators so we are trying to get them to amend the budget to fund the two new aerators. They say there are two schools of thought about pond aeration, and one school says aeration does nothing to help with the health of ponds.

Our committee thinks otherwise, but w e need some proof. Here’s my question: Do you know of any research studies that show that fountain aeration helps ponds stay healthy?

We would appreciate any help you could give us.
