Gutter System Idea... possible?

[acidrain]

So my workshop room at the back of the house has a gutter that dumps straight into the garden but where I am, the water table seems quite high so we always get the garden flooding in moderate to heavy rains so would like to redirect this water to a boundary gutter that runs out to the street.

The problem is this gutter is on the other side of the garden. The idea then is to create an underground pipe system that will operate purely on gravity. Since the building gutter is at a higher level, the water level will build up to a point where the vertical pressure will push the water out the other end.

In theory it makes sense but practically would it work without the risk of the gutter overflowing?

Below is a simple Grade 1 diagram.

Yes, this will work. I have the same with one of my gutters. I route the water first to a 1kL tank, then the overflow pipes underground (from the top of the tank) over a small wall and to the street gutters. Use 50mm PVC, it can handle a lot of water.
