I have a reservior made from a 220litre plastic drum which is about 1.2 meters tall. i have a sump to irrigate my garden in the drum and it pumps out the top through a pipe to my garden tray which sits at around 300mm from the ground. it then drains out the bottom via a 19mm hole in the bottom of the tray. is there a way to return the drainage to the reserviour without using another drainage bucket and pump? If not then what would be a suitable setup here?

The only feasible way to recycle the drainage water from the tray without an additional pump is to place the tray at a level above the top of the reservior and let the water flow by force of gravity back into the tank.
