Taking on lots and lots of water

[burliad]

Hi All,

I have a small pond with a waterfall in my backyard. I've had it for about a year now with no issues. Suddenly this week I noticed that the pond was filling up on its own. I would empty 36 gallons or more and it would be full again the next morning. After doing some investigation I noticed that there is water accumulating under the pond liner. I vacuumed out all the water and it filled up again. I suspect that water is coming up from the ground underneath the liner. I checked my water meter at my house and it's not running so there are no leaks. Not sure if there is anything I can do?

The same way you got your vacuum under the liner you want to install and leave a pipe of some sort that will not crush and will allow water to rise. water takes the path of least resistance so if you have this new pipe under your liner and it comes up to the top of your pond. When the water accumulates under the liner the pond and liner should force the water to take the new pipe you just installed as nothing is stopping it thus your problem is solved. now if you have a lot of water you my need two pipes.

Genius! Glad I decided to write in, thank you so much for the reply. I will give it a shot!

Hi and welcome! I was wondering if the sides of your pond are raised higher than the adjacent ground. This way it prevents water runoff from entering it. There is actually a name for what you have. It’s called “floating liner syndrome”!

Welcome to our forum!

Like Keith says, make sure your pond edges are higher than the surrounding ground.

Thank you all for the replies. No my pond edges are not higher than the surrounding ground. My neighbors yard is much higher than my yard. We never had a problem until now, I think this is because the house was sold and the new owners did some landscaping so they use sprinklers now. I have a feeling all this water is coming from there since my yard is always wet now too.

The neighbour might have a leak in his sprinkler system sytem that keeps feeding water.

Agree they are either running their sprinklers a lot for the new landscaping or they have a leak .You may want to let them know as boy that could be some high water bill for them and they may thank you or they are over watering and drowning the new landscaping .But do think the landscaper may have nicked a sprinkler pipe .

I would recommend for you to build a berm all around your pond so that It is higher than the adjacent ground. Not only will it help keep unnecessary run off away it will also keep out chemicals such as fertilizer and weed killer out of your pond. If you want to maintain the rocks on the edges there is a way to build one small step all around your pond so it will hide the liner. You will need to remove and replace the existing rocks to get that accomplished. It looks like a “nice” Covid-19 project if you have the time. Good luck!
