My dad has a 18 acre lake that had a drain pipe that he didn't know about until it began to leak. He found the drain end of the pipe and it is now open and draining and after lots of scuba diving with terrible visibility he finally found where it is in the lake buried under a mound of rocks near the center of the lake 22 feet underwater.
He is having a hard time figuring out how to fix it. The pipe is old and rusty and someone told him that capping the outlet would eventually cause a leak somewhere else. So for right now its still draining. Its about 2" in diameter. They sent a camera up the pipe, but from all the silt they could not see the walls of the pipe to inspect it.
One company said they could pump a grout mixture from the outlet up through the pipe and that would seal it up, but other companies have said that it may not work and not completely fill the pipe because of its deteriorated condition and create a leak in a detrimental location. Their plan was to pump 3 times the volume of pipe in grout to make sure and make it all the way to the lake.
Another company said they would bring in equipment to move the rocks and then pump the mixture from inside the lake However they are out of state and they wanted a small fortune to do it.
I would think pumping from the drain end would work because even if the pipe is damaged elsewhere the holes around the pipe would eventually be filled with grout continue to make its way to the end of the pipe inside the lake.
Does anyone have any advice on this?
