Interpretations and Explanations

The elevation of the tank provides the water pressure to all points in the pressure zone of the distribution system.For communal needs, elevated steel tanks are often constructed from factory-made galvanized steel elements bolted or welded together. However, even with galvanization, steel tanks are generally more sensitive to corrosion than concrete reservoirs. On the other hand, steel tanks can be built faster and the cost of transporting the material is generally lower, especially when concrete aggregates are not locally produced (WHO and IRC 2003).
