I want to remove the concrete block risers from one tank and replace witha new lid directly over the access hole and bury. The other lid I need to remain at grade since I pump every month.

I found a product called tuf-tite that makes risers and plastic lids, but the shipping for the items is 30% the order cost.

But that is not my question, Can I buy concrete lids or do I need to pour my own? If I pour my own, how would I do that? How thick, what type of cocrete etc?

TIA

Freak accident that I don't believe is a chronic problem.

That being said, concrete lids that I have seen fit into a tapered opening in the top slab. The lid is simarly sloped (wedge shaped) to fit into the taper. You can form a piece to cover the hole/fit in the opening and cat it yourself. I'd suggest looking up a local precast concrete manufacturer and asking if they have any stock item that would work. If not send them a sketch of what you want and have them give you a quote to make it. Remember concret is ~150 lbs./ cubic foot so it will need to be picked up or shipped which will add to the price.

Hope this helps

I will call a concrete yard and see what they have. I will also see if I can find a local dealer of the tuf-tite risers.

Quick question. You mention that you pump once per month. Why is that, please explain?
