Bill Freeman walks you through a septic tank repair and the adding of additional leach lines for an existing septic system on custom home project Freeman’s Construction is building in Ramona, CA. Thank you, Mike Tobiason, with Accurate Underground & Grading for a fantastic job!
Bill Freeman: Good morning. This is Bill Freeman, with Freeman’s Construction. We’re here waiting for an inspection on a septic system that we’ve just added onto and repaired. There was an existing system in here when we started this new house, and we just had to add onto it. There’s the new sewer line coming in, and as you can see, we had to repair the tank, because it was broken, and had an old clay pipe inside, which is what was in the old tanks. Here’s actually the piece that we took out of there. They always break off, and then you don’t get the right flow into the tank, and things can get plugged up.
Bill Freeman: As you can see, they’re a two-compartment tank, and you can see the new line we put in, and then there’s a new cap on top of that T. A lot of times, we will get a call from somebody saying that they smell sewer around their house, and if they’re on a septic system, what’s happened is that cap has either come off or it never got put on, and it allows the smell to go back up through the pipes, out the top of the house, and then depending on the airflow around the house, it will fall down along outside, and they maybe happen to have a barbecue that day, and doesn’t smell real good.
Bill Freeman: So anyway, it’s a two-compartment tank. Then it moves from this side, the solids stay in there, then comes over to this side, and we’ve also put a new outlet here. The effluent goes into this side and then flows out into the leach lines. We can see the repair that we did there, and then you can see all the roots that we pulled out of this tank. Because of those holes, it allowed the roots to get in and plug things up.
Bill Freeman: So then we did a repair down here, or not a repair, but we added onto the lines, and we used what’s called an infiltrator system in the place of the traditional rock and perforated pipe. You can see where we tied onto the end of the existing, and there’s the rock, and the four-inch perforated pipe, and then we have these new type infiltrators that we use, that are a dome shape, that go on the bottom of the trench, so they give you much more area that allows the water to go out. We had to add another 100 feet to give it the correct capacity for this particular house, which is based upon the bedroom count in the house.
Bill Freeman: Then you can see how we make the transition here down to another lower line. Once this line fills up, then it will fill up into this line, spill down over, and you have a dam here, so the water won’t cross over. Spills through that pipe, and then ties into the next level, which is approximately a foot to two foot lower, and that can vary depending on the grade of the terrain that you’re working on. Then you can see the new line here, if I jump over the ditch, that’s run, so this gets us up to the footage that we need to properly service the house.
Bill Freeman: So anyway, there’s your education for today, on septic systems. Hopefully, you don’t have to do this at your own house, but this is the way we do it, and a much better way to go, rather than use the rock and the four-inch pipe. Have a great day.
