Exit of overflow pipe - 02/27/16 11:19 PM
Looking for some advice. I have a little over an acre pond that has a 15 inch smooth walled corrugated pipe for overflow with a spillway that works if the pipe gets over ran. With the water runoff I have the pipe handles it perfectly. Usually is 3/4 full when we have a downpour. My question is at the exit of my pipe. There is a large hole from erosion that keeps opening up when the water flows out with a lot of force. I'm trying to figure out what is the best solution to control this washout and a way that I can divert the small amount of trickle that comes out of the tube when we have light rain. From the exit of the pipe to the ditch it drains to is 175 feet. I can't really afford to buy 180 feet of 15 inch pipe. Was thinking of burying a 6 inch pvc pipe to carry all the small amounts of water that flows from the pipe to help with erosion. Any advice would be great
