LAYOUT USING SUBMERGED FLOAT VALVE 8.1.3 Protection Around Tanks Livestock can wear the ground down around a tank very rapidly, particularly under wet conditions. If the ground is not naturally gravelly, a gravel or concrete base should be installed around the base of the tank. Figures 8.9 through 8.11 show examples of good tank bases. 8.1.4 Tank Overflows Tank overflows are required when there is no control on the amount of water coming into the tank. They are also highly recommended even when a float valve is used to control flow into the tank. Float valves occasionally do not close properly and an overflow is insurance against damage caused by overflow. The purpose of an overflow is to carry excess water away to prevent excessively wet conditions around the tank. The overflow should be extended to a location where it will not cause a problem. Typically it should be at least 50-100 feet from the trough. If wetland conditions will be created as a result of the overflow, they should be located where the water would naturally collect. Consider protecting the overflow area to retain or enhance any wetland values that may be created. The inlet to the overflow should be constructed at the elevation of desired water level in the tank. The entrance should be designed to prevent clogging by floating debris, scum and ice. Figure 8.12 illustrates some commonly used overflow systems. The outlet end of the pipe should be protected from being damaged by livestock or vehicular traffic. Figure 8.12 OVERFLOWS 8.1.5 Inlet to Pipeline from Tank When an to a continuing pipeline is located in a tank, some form of inlet screen should be installed. Figure 8.13 illustrates two types of inlet designs.
