Chamber Lid

I am putting a Riser on my Outlet Chamber. Right now, there is no Riser and the lid is concrete. After I install the Riser (which is about 32"), do I keep the concrete lid on or throw it out?

The only risers I have installed were a very heavy PVC material and they had PVC covers.

Ive heard of concrete risers but not sure what they use, what does the manufacture/seller recommend?

I've seen it done both ways. If your old concrete lid can be removed with the riser in place then I would leave it for safety. If a child or someone gets the lid of the riser off it will prevent someone from falling into the tank. Keep in mind that you will have to be able to lift the heavy concrete lid up and out through the riser when servicing the tank. My tanks only have lids on the risers as the tanks are too far underground to make removing another lid practical.

Thanks so much! I will remove the lid underneath the Riser, since it is extremely heavy and about 2.5 feet below the Riser (which has a lid of its own). Thanks, again!
