These structures are usually located in the center of the city neighborhoods and made up of four main parts:

1-A reservoir, which is cylindrically shaped and below the ground surface. The water, coming from underground canals, pours into this reservoir;

2-A dome built over the reservoir, which keeps the water cool;

3- Pasheer, the platform, which is used for taking water from the reservoir;

4- Badgir, a weathering shaft for bringing in the air current in order to protect the water from spoiling.
