The Pump is in the Pond – Our Off Grid Irrigation System

Hello and welcome.

In a previous post I mentioned that we would soon be putting the pump in the pond so we could water our gardens when necessary. I also told you that my husband had said it was my turn this year to put the pump in. Let me start by explaining how this works.

Each spring when it’s getting close to time to put the pump in the pond we have a conversation like this:

My Husband: It’s your turn to put the pump in the pond.

Me: Okay as soon as we have 3 consecutive days of 80-degree F (26.6C) temperatures so the water warms up.

My Husband: Puts the pump in the pond even though the water is still colder than is comfortable.

OR

My Husband: It’s your turn to put the pump in the pond.

Me: No. It was my turn last year.

My Husband: I did it last year.

Me: I know, but it was still my turn last year, so it is your turn this year.

My Husband: Puts the pump in the pond.

THIS YEAR

My Husband: Are you ready to put the pump in the pond tomorrow?

Me: I told my readers I would take pictures and blog about it. I can’t take pictures while I’m in the pond.

My Husband: Puts the pump in the pond.

The truth is while I know how to put the pump in the pond and could probably do it if I had to, it’s one of those jobs that my husband is willing to undertake. (He’s a great guy!)

Dual Purpose Windmill

If you’ve been following my blog for a while you have likely seen pictures of our windmill. Some readers might also remember that our windmill is used both to aerate the pond and pump water out of the pond for irrigating our crops.

Aeration

The windmill works to aerate the pond year-round.

In the above photo the bubbles in the water are cause by the windmill.

In the above photo the hoses attached to the windmill run down into the pond where they are attached to porous devices called stones. We have two stones located in different areas of the pond. When the wind makes the windmill turn, air is pumped through the hoses and comes out the stones and into the water, thus providing much needed oxygen.

Irrigation

We only pump water for irrigation during spring and summer (the growing season). This year we put the pump in the pond on Wednesday, June 4. Below is a picture of the pump that we use in the pond.

Notice there are two valves. The one to the left is marked “To Windmill” (the words are upside down in the picture). A hose attaches to that valve and the other end of it attaches to one of the valves on the windmill. We unhook one of the aeration hoses since we do not aerate and pump water out at the same time.

The valve on the end is marked “out”. That is where the water is pumped out. A different hose is attached to that valve.

That metal piece on the right end has many small holes in it and is where water flows into the pump. The tube attached to the cap-like piece on the top is a vent.

When the pump is in the pond, bricks are placed on top of that long bar attached to the bottom to hold the pump in place.

Both hoses are attached before the pump is put in the pond.

This year the water wasn’t too cold. The pump will be fully submersed in several feet of water

expect for the vent tube.

I regret that I can’t show you, or tell you, how the magic works inside the pump. I just know that when the windmill pumps air in, water comes out. If the windmill is not turning, water does not come out. Also, when the windmill starts turning again a small amount of water squirts out the vent tube in the pond.

The hose that the water comes out of is run to one of our holding tanks. We have three tanks strategically located.

The hose is about 120 feet long, which is more than enough to reach any of the tanks.

The tank is filled through an opening in the top.

My husband installed spigots near the bottom of the tanks so we can attach a garden hose. We can use the garden hose to fill watering cans or sometimes we water plants directly from the hose.

Within a few minutes of having the pump installed water was running through the hose.

How fast we can fill a tank depends on how much wind we get and the wind direction. When we do not get enough rain to keep things watered, wind is the next best thing.

Thanks for visiting.

P.S. My husband just informed me that next year is my turn to put the pump in the pond. Uh, no. This year was my turn. 😉
