Septic Tank/Water Table Issue


Good morning,

New guy here, looking for anyone that can provide some information...

Installing a NORWESCO 1000 gal plastic septic tank that requires a 12" concrete foundation anchor slab for anti-buoyancy. During excavation, I have reached the water table. I have tried pumping it, letting it dry, etc..nothing has worked. Is there a common practice that anyone knows of for stabilizing that excavation in preparation for that anchor slab.

Thank you for any help you all can provide.

-Erik

Dig a hole next to the area, deeper than you need for the tank work and pump constantly until you are done with the tank work and backfill.

It will still float!

There are some concrete tanks built with a taper to them so as the bottom of tank is bigger than the top. They also have a conc. ballast at the bottom to help keep from floating.

Re: Septic Tank/Water Table Issue


When I had my system put in I asked the excavator about using a plastic tank.
He told me he would use it if I had the septic company fill it the day he put it in to keep it from floating.
Pumping the new tank full of sh** before it even gets used? I told him use the concrete tank.

Concrete ones are cheaper than plastic and they include delivery

I can get a concrete one for about $600 last time I checked.

$930 for this plastic one.

Re: Septic Tank/Water Table Issue


I think I paid around $2000 for a 1500 gal concrete almost 2 years ago.
That included manhole and filter on the out flow pipe (required here now).

Concrete tanks float. What tom said. How much water you talking, what type of soil?
