Quick Update...
Finally started to really draw the attorney card about a month or two ago. Suddenly, everyone became a lot more responsive.
Long long long story short...
A different septic company came by and dug some small test holes by hand...easy digging in this sand. They verified that the organics/clay layer was never removed. They stopped hitting organics/clay about 16" down.
Another soil classifier was also sent by and did soil borings...he also verified that the organics/clay was not removed. He also discovered some roots and clay in the fill that was supposed to be clean sand fill. He advised removing this fill where possible and replacing it with the fill that is to be brought in (see below).
Both of them reported into the engineer. We all met and/or talked on the phone a few times and devised a plan to get this thing fixed once and for all.
1. All of the original septic system minus one of the original beds will be removed and the spoils hauled away. One bed is being left in service so we can stay in the house. This is a big deal since my wife and I both work from home.
2. As much of the soil in the buffer zone and taper of the original bed that is being left behind is to be removed.
3. Septic installer will continue to remove material until all organics/roots/clay has been passed. The installer advised that this has been as much as 4ft of material in past installs, but is usually <2ft.
4. Clean fill will be brought in to replace all removed soil and to build up the area of the septic system to original grade. I hand delivered a sample of this sand to the soil classifier and he verified that it is a "Class 1" sand and is perfect for septic systems. This is the fill that was originally called out in the engineering drawings.
5. The new septic system will be installed per the new engineering drawing. This septic system is identical to the design of the original septic system in size. Therefore the resulting system (remember that one bed is being left behind) will be 150% the size.
6. Sod will be brought in to cover all exposed soil.
I have not been asked for a dime, and will not be paying for any of this.
We have now had this issue for ~1yr and have had our septic tank pumped 6-7 times at 300-400 dollars a pop.
I also talked extensively with the DHEC during this time about what is going on.
I hope this fixes the issue, and I will keep doing updates until this is resolved. They are supposed to get machines delivered and the fence to the back yard taken down today.
I forgot to report earlier...but was looking at getting gutters on the house (builder offered to pay and sent a gutter company over). I finally agreed after some back and forth and they came to do the install. We have a shadowboard on our fascia (essentially a stepped fascia). Instead of getting the special brackets that fully support the gutter with this style fascia, or installing a PVC adder board to support the fascia, the gutter installers were going to tuck the gutter up hard against the shingles and OVER the dripedge. They showed me what they planned to do and after explaining to the installer all the things wrong with what they were doing I asked them to leave...so, no gutters yet for me.
I have since noticed that there are TONS of gutters installed this way down here. Many of the new developments have house after house after house with the gutter up tight to the shingles, over the dripedge, and inadequate support for the gutter. The question I keep asking myself is...in an area that gets as much rain as Charleston, SC...why the heck would a shadowboard be used on the fascia, which makes gutter installs more complicated ?! Especially since the gutter will cover the shadowboard detail anyway...
Makes me sick to my stomach looking at some of the building practices down here and I wonder what issues I will have with my house in the future. Good thing the beach is so close so I can crack open a few Coronas and forget about it on the weekends
