| − | The outside wall need not be treated in this manner. Expanding sheets of ice are pushed upward and the pressure on the walls of the tank is diffused due to the wider width of the tank's top interior. This is a point made to us by the northern Iowa farmer who has all concrete tanks on his farm.

| − | The best cover for tanks according to the farmer who owns the hollow tile tank, is a cover made of reinforced hollow building tiles and concrete. This structure is able to prevent the formation of frosty air in winter or hot air in summer because of its thick and permanent composition. Transmission of heat and cold is prevented by the dead air space present in the tile.

| − | The need to have a water storage tank can be as simple as wanting to store rain water or it can be necessary to the lives that depend upon it for their supply of clean, fresh, and bacteria free water. Whatever the reasons for a water tank, the design that will store the supply is very complex and depends on several factors. Water tank design relies heavily on size and use, as well as, materials that are to be used in construction. Tanks are constructed of steel, concrete, and fiberglass. The diameter and height of the tank determines the amount of water that can be stored.

| − | There are three types of water tanks:
| |
| − | | |
| − | • Elevated
| |
| − | • Ground level
| |
| − | • Underground

| − | The elevated tank is seen most often in townships or cities, while ground level and underground tanks are used more-often for individual homes and farms. Elevated tanks are designed to stand above the ground on foundations of steel and concrete. The higher the elevation, the more PSI the tank will have, with every foot in height adding 0.43 PSI. PSI (Pounds per Square Inch) is extremely important to water tank design. PSI translates into pressure, and pressure determines water flow.

| − | While elevated tanks provide the best pressure, they are far-more expensive and generally, only used where supply is in high demand. Ground level and underground are beneficial where there is smaller demand, for water, by a single home or for irrigation. Ground level tanks are exposed to the elements and will require regular maintenance to the exterior shell. The underground water tank eliminates exposure to weather conditions but must lie above the water-table level.

| − | The location is another important consideration, to keep in mind, when deciding upon the design. Depending upon the water source, the tank may be several hundred feet from the water supply. With this in mind, your water tank design will have to include pressure consideration and the delivery route from the source to the tank. Regardless of the positioning of the water tank, the location must have a soil test done to determine moisture content and soil compaction.

| − | Maintenance for your system will help you determine some of the other factors. Maintenance must be done, at regular intervals, and the tank must be accessible for cleaning. Weather conditions and drainage must also be factored in to the design. The AWWA, located in Denver Colorado, is an authoritative source for information on well water, and water tank design and maintenance.
