I currently have a 24" outlet pipe, two 20 footers with a collar that appears to be leaking. The water goes over my emergency 2 or 3 times a year. I am thinking about digging up the pipe, lining the area with clay then installing a 45 mil pond liner, covering the liner with sheet aluminum then oversize septic rock. It will be 18' wide x 3'deep and 35' long spillway. Am I missing anything? Any Ideas on a who to purchase the liner from?
