We do the same. :thumbup1gif:I have never had any issues driving over either the solid or liquid dosing tanks, nor the piping connecting the two tanks. I do pay "some" attention however to the drainage field. I haven't had any issues, but then again, when ground is drying in spring or after very heavy rains, I minimize going over the field to prevent unnecessary compaction. That's just me, as I tend to be overly cautious.
I wouldn't lose any sleep over it though.
The critical issue is if the tank is a shallow (gravity tank) or deep tank (pump out system). Also the material, concrete or fiberglass. I wouldn't drive over a fibreglass tank unless it is buried quite deep.So far so good with a 2320, but now you have me asking myself if it is worth the risk. It is not. I can mow that with the 316. If it goes bad it will cost too much. Doesnt meet my acceptable risk criteria.
I'm not saying one shouldn't use caution, not at all. I don't go around hap-hazardously driving bulldozers over my septic system either. But has anybody ever seen a septic tank failure where it caved in? The only failure I've seen or heard of is failures within the system such as roots, clogs, pipes broken, plugged up, and installation errors. It's just that this subject comes up every so often but for the life of me, I don't know why. Has anybody seen or heard of an actual failure in this manner? I'm curious.
In your opinion, do any of these failures have anything to do with lawn care equipment or tractors driving over them? Or is it just a time thing?I install residential sewer systems for the last 4 years and have seen 5 collapsed tanks now.
Almost fell in once in a 6 foot buried tank. Escavator took two scoops Right where I was standing. We were looking for a buried cover and the ground dropped right where I had been standing.
Sewer gases eat away the concrete.
The guy i work for tells people you get about 30 years out of a concrete tank before you need to start worrying about it collapsing
