Carrying the mantle of doubt
Last Saturday I went to Menards to pick up a few items, and when I returned home and pulled the car back in the garage, I heard my septic alarm going off. We have a primary 1200 ga digester, and a 2nd 1000 gallon tank with a grinder pump that sends it up to a mound system.
I figured the pump died (again ) so I just shut off the alarm. Typically, it goes off at about 500 to 600 gallons full. Sunday night I called the septic guy and he said to check the pump ... it might still be running. So, I hiked out there and sure enough I could hear it through the access cap, but it sounded like it was cavitating. Septic cap was frozen on so I just opened the electrical box and unplugged the pump.
Took off work Monday and after a laborious hour, managed to unscrew the frozen access cap ( about 2ft. diameter ). Look in, and the level was about 1/2. Huh? How could this be cavitating? Plugged the pump back in and could see water blowing out the effluent line weep hole, back into the tank...which accounted for the cavitation sound. The effluent line runs uphill to the mound, so there's a small 1/4" hole to let it back drain when the pump cuts off. Seeing this, the despair hit me as it was likely either the effluent line and/or the mound was froze up. With these weeks of sub-zero weather and little or no insulating snow cover, the septic guy said he's seen frost down to 5 ft in some areas and a lot of homes are suffering this demise.
So, Tuesday the guy came out and tried steaming out the effluent line, but had to quit due to equipment problems. Today, he came back out and pumped the second tank and said there's most likely nothing to do until spring thaw. The newly emptied tank will let ~1000 gallons leave the house until it needs to be pumped again.
So, for conservation, I've decided to reroute the kitchen drains to the basement laundry tub (easy ), and then plug the tub to catch the kitchen water and the wash machine output. Using a portable sump pump I have, we'll have to periodically empty the laundry tub out into the yard with a hose. Then, all we'll be putting down the septic is toilet flushes and showers, for both of which our habits will need to change for a while. I'm thinking with these measures we'll be able to go well over a month before another tank pumping is required.
As for improvements to the mound system: The asshole who installed this system 25 years ago didn't put enough top soil on the mound. In addition, the effluent line is only about 2 ft under. So this spring after thaw, using that nice little Kubota loader/backhoe I bought a year ago, I'm going to dig up the effluent line and replace it with a 3" PCV pipe. Inside that, I'll run the 2" effluent line along with a 300W heat tape and a thermostat back at the septic electrical box. That should keep the effluent line from freezing ... ever again. As for the top soil, I'm probably going to have to get a few loads of dirt/loam and spread another 6" over the entire mound, again using the tractor rather than moving 50 yds of dirt by hand. Don't have that sort of manual labor in me anymore, hence the tractor.
Not sure the dirt alone will keep the mound from freezing in low-snow winters like this, so I'll probably cover the mound with my fall leaves and plastic it down for the winter. Fairly easy to do as I have to haul them off anyway.
All in all, quite the unexpected pain in the ass, but I will prevail in the end.
