How do drain layers get minimal slope on pvc pipe?

I have a slight downslope away from my house. I want to run 90 mm pvc storm water pipe from a catch basin/access pit in a straight line down the slight slope to 8 m away to discharge to daylight near my garden.

The access pit has a female socket for the pipe at (I presume) 90 degrees.
The top of the access pit is supposed to sit flush with the top of the ground.

Note that this drawing is not to scale and also exaggerates the slope of my lawn. It shows what I would like to do with the pipe.

1 in 100 is such a gentle slope that you might be able to just glue the pipe in then immediately before the glue sets bend the fitting slightly. Otherwise just get a plumbquik coupling (black rubber joiner with hose clips) Cut the pipe by the pit box leaving enough to join onto. Then use the plumbquik to rejoin the pipe and get your angle.

They don't officially make a 90mm plumbquik but an 80mm one should work fine.

What type of pipe are you using?  If it is waste water, then the walls are thin. There will be enough flex in the pipe to get the drop you need. It may take a couple of meters to do so but so what? If you are using pressure pipe, then the walls are thicker and it will need a little more distance to flex the desired amount. If you are using down piping, then the walls are ultra thin, and there will be no issue. Can you pick up the pipe and see how much it flexes under gravity?

If you can't work it out get a drain layer in, most pipe I have seen allows a certain amount of flex unless you are trying to use metal or concrete pipe which I doubt. Long lengths of PVC pipe should have enough flex to do what you want.
