We had a leak in our irrigation system that was causing a lot water to pool in our front yard. The moisture and the humidity caused a swamp to form. Joe and friends had to dig up the the swampy parts of the yard to locate the damaged pipe. We discovered that tree roots had literally grown around a pipe and cracked it. The only way to remove the roots was to also remove the pipe, so we replaced it.
You can tell by the photos that it was a very messy situation. But grass has almost completely been regrown over it, (see bottom picture) so we have finally bid adieu to our swamp. Many thanks to Pete who was stellar on this project, and of course Jake who has someone managed to get roped into all of our home improvement projects. Now I know that neighbors are good for more than just sugar!
