Pond Boss Forums POND CONSTRUCTION Building a dam Increase spillway pressure outflow

Hello, summertime.

The only way to increase the pressure on your outflow (for "free") is to increase the "head" - vertical distance between the water level in the pond and the elevation of the outflow. So you can raise the water level (non-trivial for most of our ponds) or lower the output.

If you have a near constant outflow, you could have it enter a smaller pipe at any level below the pond surface (to ensure that this pipe always receives the water first, preferentially wrt the 2 foot diameter main drain) and tap into it's outlet far enough below the damn to suit your needs. If you have enough drop behind (below) the dam.

If you want the water wheel turning for ornamental purposes, you could of course pump water to it.
