Large capacity water tanks (figure 1)

Where large storage tanks are used (with the capacity to store two or more days’ water supply for the farm at peak demand) and the water usage output is a proportionally low ratio to the total storage volume, then a system can be used where the chlorinated water enters the primary tank at the bottom and the chlorinated water enters the secondary supply tank from the high level outflow. In this set up, the dilution rate of the fresh water is low and the bottom of the tank input and the top of the tank output ensures the water is effectively sanitised. The certainty of this can be enhanced by adjusting the chlorine dosing pump to ensure that the chlorine level in the second tank is maintained between 1 to 5 ppm, achieving 1 to 2 ppm at the drinker level.
