It was about 1996, at Yarrow Bay above Kirkland Wa.

I worked as a general day-laborer for a home builder and was hired to help a different company build a outdoor pond infront of a new home.
(So I was really working for a builder who lent me out to a pond company for a few days.)

The pond they made was about 25 feet long, about 10 feet wide and at most about 4 foot deep.

The day before the house was sold and the new owners moved their stuff in I saw the pond people working on the pond.
I saw they drained the pond and cleaned it, then added new water.

The pond really looked good the day the new owners took over the keys.

But 24 hours later I noticed that about 1/2 the water in the pond was missing?

My boss also noticed and so he told me to run a hose over and fill it up.
My boss was also upset at the pond builder for not filling the pond all the way up with water the day before for some reason?

2 days later on December 24th, (Christmas eve) I received a phone call about 6:00 at night from my boss.

My boss was out of the state but had received a message that the new owners of the home with the pond were saying that they were right in the middle of their Christmas dinner, (with a home filled with people) when water started to enter their basement!

My boss said he could not get a hold of anyone who worked for the company who built the pond so he wanted me to take a wet/dry shop vac over to that house and suck up any water getting into the basement.

I went over with my shop vac and the people there took me down to their basement.
Thats where I saw what was going on.

'OH MY GAUD!"

The Christmas tree was laied out on it's side, the many gifts on the floor showed signs on their wrapping paper that they had been under water.
The people had ripped up the room's carpet and the whole house smelled of a wet dog.

I did what I could with my little vac, but there was WAY too much water flowing into the basement for me to stop.

After 2 hours I gave up , I had done what I could but there was no sign of the water ever stopping.
The people thanked me for helping them and I left the shaop vac for the people to use on their own.

Im told they didnt sleep for about the next 72 hours fighting the flood.

Later I saw that the pond was filled in with dirt and was a flower garden now.

I asked my boss why?
The problem turned out to be the bottom drain.
The bottom drain had been working well for a while, but we think the people who had cleaned the pond just days before the owners moved in had cracked something underground.

It may have been a pipe under the pond, or a fitting that was not glued right, or perhaps something else, but whatever it was it meant that this pond would never be able to hold water.
Or if it did hold water, it could never really be trusted 100% in the future.

This is why I am against pond bottom drains on ponds that are close to homes or a property line....

(I wrote the above as part of another topic but I have been thinking all day about what I have writen and felt I needed to share this point of view of mine as part it's own topic.)
 
I'd rather have filled the drain with a bag of cement rather than fix it with a truck load of dirt.
 
My guess is that the owner wanted no part of such a problem ever again?
The position of the pond was at points right up next to his house.
Given the mess the bottom drain had cause during Christmas I can understand backing up a truck and dumping dirt into the pond.

Now I got nothing against a working bottom drain in a pond thats out away from the house.
If it ever failed its more than likely not going to be a problem within the home.

But for ponds that are placed right up within 10 or 15 feet of a home I believe that a bottom drain is like adding a form of Russian roulette to your life that you just dont need.

In the case here of the home with the flooded basement, you can see how the fate of that basement was connected to the fate of the plastic bottom drain forever.

Just not worth it , in my point of view.

:iagree::iagree::iagree:

ANY pond can leak if constructed wrong or damaged. Tragic story tho. It's a shame the house foundation wasn't sealed properly (no sump?).

Sounds like the owner never really wanted it.

Besides I didn't know water flowed in Washington State in the winter :ROFL:.

a four foot deep pond would have to be below the frost line...... right ? and the water would flow i know here in ohio the frost line is around 3 feet so as long as you have an outdoor pond 3' or deeper then you should have no problem with it freezing completly.


I could be wrong thou washington is just a tad north of ohio if you are in the northern part of washington

Kirkland is a small city just outside seattle, and in seattle you have very mild winter temps due to the warm sea wind heating you in the winter and cooling you in the summer.

The problem was not that the pond had a bottom drain and it leaked,,,(leaking bottom drains are something that has been known to happen to many ponds)
The problem was that the pond was located right up next to the house , WITH the deepest part of the pond just a few feet away from the house.

This means that the fate of the basement was forever connected to the fate of the bottom drain and the skills of the guys that connected it...


The other problem was that the pond was a cement pond not a pond with a easy lifted up plastic liner...
And that the landscapers had placed cement sidewalks all around the pond on 3 sides and on the other was the driveway.
This made it hard to get at the pond drain fittings under the pond.
Even if the owner had decided to learn what had gone wrong and fixed the problem it may well have meant a lot of jackhammering and loading of cement chunks onto trucks.

This is all why I believe that pond bottom drains are a bad idea if the pond is set close to the house.
 
There are millions inground pools with drains, and yes I'm sure that as with anything that is constructed there is a chance of failure. I can't imagine what it would take to empty a large amount of water without a drain :screwy:

If I wished to build a very large pond right next to my house or within spitting distance of the guy's house next door, I would not design it with a bottom drain.

You could never be sure about it in the unknowns of the future.
Anything can leak if given a chance,
Most people would want to build a pond that will have as best of chance as can be had for not leaking...
Bottom drains are not always the only way to drain a pond down.

I think that other ways to suck out the pond water would work just fine, and they would not come with the built-in danger of a leak in the future flooding anyone's basement.

Now bottom drains work just fine on ponds that are set off away from anyone's house.
If they leak all their water out one night no one ends up in small claims court.
But when you design a pond that sitting right up along side a basement wall (as was the pond in my story) then I believe a bottom drain is an un-needed risk.
