Why do you have a series of small holes on top of the lid?

28 Dec, 2016

Some newer manufacturers of rain barrels make larger holes in the lid with a screen below. We have 8 x 3/8″ holes in the top of the lid. There is no need for more. This lid serves as a tray and the water drains into the barrel, acting as a filter to prevent unwanted debris from getting inside. If the holes are too big the screen beneath could easily be damaged by debris exposing the water and inviting mosquitoes to breed. The firmer lid also serves as host to stones or plants to create a more interesting aesthetic for your barrel. The amount of roof runoff captured by your downspout determines how much water goes into the barrel not the holes in the lid.
