I am 78 and am constructing my first water element. It is about finished. My problem is I am not quite sure how to handle the return water at the top of my 60 foot effort. It curves down hill and consists of two small ponds about 8 feet across and 8” deep and a 5000 gal pond that is 45 “ deep. I have installed a Savino CS 16000 skimmer that will hold an Easy Pro TH 750 5900 GPH connected to 60 feet of 2” PVC that will circulate at about 50 GPM. I have two small waterfalls coming out of the two small ponds and I do not want a large waterfall at the top of the element. I thought sinking a 50 gallon plastic drum and letting it flow into the top channel. Any ideas??
You are using one pump for two waterfalls and also to get the water to the top channel? I will assume that is the case. If so, you may have some problems getting water that high with your pump. If you are already successful doing that, you could easily use a 50 gallon drum. You could also buy a spillway that already had a low spot for water to flow out. They are relatively cheap, but they do not have a real long shelf life. They are plastic and vulnerable to the sun.
I am also assuming your channel is lined with something, rubber liner or concrete. I am hoping for liner. Be careful that the water at the top channel drains onto the liner and not under or to the side of it.
One of the problems with 8" deep water that I have often run into is that a stick or leaves can fall into it and soon a few more and soon after, you have an unplanned dam and water flowing out the sides pumping the pond dry in the process.
Congratulations on doing your first water feature at 78. I was a child of 48 when I started my pond building business many years ago.
