Going big

I have a friend who laughs at my projects. She says I don’t do anything small. Now, I have to admit that she’s right.

This hot summer has really gotten me thinking about rain barrels. It’s the smartest thing in the world to catch otherwise wasted water and save it for watering the garden. It reduces run-off and conserves water. So smart.

In Texas, there are a dozen firms that specialize in rain catchment systems. I couldn’t find any in Minnesota, so I started talking to my neighbor, who is an excavator (and rain barrel enthusiast) about creating one for me.

Of course, I had a challenge. Normally rain barrels sit under downspouts. But our architect didn’t spec any down spouts for our house when we remodeled it this spring, preferring instead to have wide galvanized metal gutters without downspouts. They look great, but heavy rain drills holes in my lawn.

With the help of my neighbor and his crew, we installed a cool new system last week. The water falls into in-ground 12″ x 12″ basins placed under the end of each gutter. From there, it runs through underground tubing and collects in a 1300-gallon concrete underground holding tank! Now, that’s one big rain barrel!

It hasn’t rained here since they installed it, so I’m keeping my fingers crossed that we get that storm later today. For so many reasons, both small — and big!

LOL! I thought that was a giant beehive! Where in the world can you hide such a thing?

That’ll hold a LOT of squirrel swimming classes!

Seriously, though, what’s the mechanism for getting the water out? A ladder and a bucket? :)

Since the tank is buried (a tank sitting in the yard would be Ug-Ly), I’ll need to use to a pump to get water moving into the garden hose (there are openings on the top, which you cannot see in the photo). It’s not perfect, but it’s also not an eyesore. I don’t think I could coax a squirrel down the hole, though .

Wow. What happens when Robyn gets the itch to reduce her carbon footprint?? A windmill that provides power to all of Scandia????

More power to ya for catching every drop! I use a simple stock tank to catch water off my garage/greenhouse but I got to liking the fish I put in there (to gobble up mosquito larvae), that it’s really more like a water feature now. Great for watering potted herbs nearby.

That’s no rain barrel, it’s a fall out shelter for water! :)
Simply awesome!

It is basically a repurposed septic tank right? What’s the difference between pumping the water out of this tank vs pumping it out of a well in the ground? About 80 ft of lift or so? This seems like it would be a great solution for someone who is hooked up to more expensive city water supply but the cost savings in electricity to lift it the extra few feet out of a country well would be negligible. Maybe the water table is way low out that direction and the well would have to be a few hundred feet deep.

Hey Jeff, you’re right that it’s a repurposed septic tank. Was going to put in a fiberglass tank, but the concrete one was cheaper. And you’re right that cost savings isn’t significant, nor in this case, the focus. I needed a way to get water away from the house due to the gutter problem. I could have used the catchment system to just run overflow to daylight, but I figured I’d save that water for the garden while I’m at it.

Wow, R & D what a great plan! What happens to the water in the winter–is it below the frost line?

I hope you got to try it out yesterday with the rain. Of course here in Blaine we didn’t even get a enough to measure in rain gauge.

What does something like that cost. I’ve been looking for a way to collect water off my roof too.
