When I was researching nomenclature for my Building Materials Lexicon webpage, I found great variations in what water tanks are called in various parts on Mexico. This is what I settled on for my webpage:
water tank = tanque de agua roof mounted = tinaco in the ground (cistern) = aljibe on top of the ground and sometimes in the house = pila Both the aljibe and pila are typically made with bricks and stucco. Sometimes a plastic tank is used in which case it is often called a tinaco no matter where it is located.
In some areas a water tank is called a cistrerna no matter where it is located or how it is made.
