A sāqiyah or saqiya, also spelled sakia or saqia) is a mechanical water lifting device. It is also called a Persian wheel, tablia, rehat, and in Latin tympanum. It is similar in function to a scoop wheel, which uses buckets, jars, or scoops fastened either directly to a vertical wheel, or to an endless belt activated by such a wheel. The vertical wheel is itself attached by a drive shaft to a horizontal wheel, which is traditionally set in motion by animal power Because it is not using the power of flowing water, the sāqiyah is different from a noria and any other type of water wheel.

An acequia or séquia is a community-operated watercourse used in Spain and former Spanish colonies in the Americas for irrigation. Acequias are found in parts of Spain, the Andes, northern Mexico, and the modern-day American Southwest.
