Whats the situation exactly? How old its it, are you doing it for youself or someone else, and how far does it have to go? Easiest thing to do if your flexible on the timeline and the pick points are still ok is call up your local precast tank manufacturer and tell them you have a tank you'd like to move next time they are in the area.I Had one moved for 150-180 bucks that way. Simply opened it up around the tank, had it pumped, and had the new hole ready to go, took less than an hour. If you go to tipping it and doing weird stuff your probably going to break it. they will take some abuse, but not alot. If you really want to do it the bohemian way dig a gradual ramp and sling a nylon strap around the base, kind of like a horizontal basket, I've skidded them this way before, but it was less than 10 feet, and getting it back in the ground will probably be a PITA, let alone to the grade you need it at. Leave the lid on, and I wouldnt use the stick or bucket to physicaly push it, I caved in the pump tank on a 1500 combo doing that on one that was floating in ground water on us. Key is spreading the pressure out as much as possible.
On the legal note...... If you are reusing this for a residential sewer and your the owner, you can legally do it all on your own, but you need a permit, a septic design, and it needs to be inspected by your county or local unit of government. Also to re use it it needs to be water tight (Duh right) and the right size for your application, which a 1500 combo will be for 75% of the systems you'll run into.
This is being done for myself. The tank was made by a small company that made quality tanks, not ones egg shell thick. As for calling the local pre-cast company, the last time I wanted a tank they would not sell me one. But no problem, I called a pre-cast company 80 to 100 miles away and bought one from them. That was a 2,000 gallon two compartment tank. The pre-cast company close by lost a sale. Why would they not sell me a tank, I was not currently liscenced. The local licenced installers did not want home owners installing their own systems. They presuaded the local company to only sell to the local installers. The last system I installed the materials were about $1,500 and it took me a couple of days to put it in. I could have paid a licenced installer $5,000+ to do the job in one day while I was not there and I would not have known what kind of job I got. I have seen the mess some installers make and they still get paid. I have heard where they have installed half of the designed system, got paid for the complete system. A neighbor close by got one of those. I installed two systems for a couple of friends and after I left you would not know I was even in there. All dirt that was replaced with rock and pipe was hauled away, the black dirt (topsoil) was put back in the trench on top of the fabric, the elevation of the area where the tank and drain field was installed was not changed. Two weeks aftrer I left you would not have known anyone had put a septic system in, their lawns looked un-touched.
I was planning on doing it the bohemian way putting the strap as close to the bottom as possible so I am pulling against the bottom and not against the side walls. As for putting it back in the ground if I am a couple of inches off in elevation I have enough distance to adjust the slope of the pipe to still be within the acceptable limits.
Yes I plan on getting a permit, I will have my wife issue it to me, if she is busy my 12 year old son can make it out. I think I can design it myself. The system that I stopped using had six drain lines connected with drop boxes. I dug through that system when I hooked up to city water and sewer. Only one drain line had water in it and not much. The system was 25 years old. Looks like I could have got another 125 years minimun use out of that system. I have had systems inspected by county inspectors, what a joke if the ground is wet because of rain they won't even get out of their car. If it's a nice sunny day they get out of the car and stand on the nearest grass for the inspection, don't want to get their shoes dirty. I don't know what they are inspecting, My 12 year old son can do that and more, he dosen't mind getting dirty. I think I will have my son do the inspecting he has common sence.
The tank is a 1500 gallon single compartment tank, should be acceptable for a 2 bedroom cabin. Plenty of retention time for the solids in the tank.
Next time you go to one of your re-fresher classes tell Dave hi, he created quite the job for himself. His side kick with the ponytail (Clarance) has a hard time saying some of the things he says. Might be a carry over from his Hippy days. Dave used to put on a good class, now he puts in a lot of unessary b.s. for filler material. Like his backhoe video, he might not have known what a backhoe was until he saw the video. He is now sharing that new found knowledge with others. If you have not noticed the one class he used to put on is now done in a couple of classes. Everyone gets to buy another class or two and he has long breaks during the classes because he could have combined all the material into one class.
Thanks for your input, won't be long before we will be out playing in the dirt unless this snow doesn't melt till June. Then it might take awhile before the water gets to the Mississippi.
Have a great day
