The first reservoir extends from a first side of the barrier to the first opening of the hole and the second reservoir extends from a second side of the barrier to the second opening of the hole. The barrier is made from a material different from the first material. The barrier is semi-permeable and non-biodegradable and has a thickness which is less than the depth of the hole.
