These goals will be realized by the utilization of the depicted apparatus. The constant head tank was constructed using two elevated buckets. The storage was significantly larger and with a larger diameter than the actual constant head bottle. They were connected by a single tube which went from the base of the stock tank and into the top portion of the bottle where the float was located. From the bottom of the bottle was a from which the dosing tube was attached. This tube is adjustable to allow for different lengths. A PVC pipe was procured and sealed on the bottom and placed in a wooden base to stabilize it. In this, along the top 26 centimeters, 26 7 mm holes were drilled. The top hole had its center line leveled with the water level in the constant head bottle so that ever additional hole below was another center meter centimeter of head loss.
