Under that ugly mess in the image is a dual chamber septic tank. I want to cover it with something that can be driven over safely but still have access for servicing.
I am guessing at a reinforced concrete slab with 2 manholes.
Each chamber measures just over 6ft x 3ft, with 9" concrete walls all around, arranged as the diagram attached.
The intention is then to cover everything with chippings to lose sight of it. I reckon I can afford at least 4" thick without it being exposed but dont really know where to take it from there.
Got to be a pre-cast concrete slab over the top - not sure if there is anything available off the shelf in that size!
Doing it on the cheap? What about a steel roadplate over the top? Thinking about it, the corrosion could be a problem in the future - don;t want to loose a car down there!

I would of at least have a local fence around that secured tightly and something heavy to hold the ply down, kids love hidden dangers. if you are worried about the height , maybe you could take a course of blocks off and bring it up to level with a "biscuit" and brickwork? if you need to cast a thicker slab, maybe some corrugated metal sheeting, mesh over that. then boxed out recess for the frame and cover?
