The water systems in most of the houses are gravity feed only
Water is stored on the roofs of buildings in either concrete or, more recently, plastic tanks. Every building has a pump to fill the tanks from the water main in the street. This is usually done at night.
When constructing a new apartment and adding additional water supply, tanks must be hoisted to the roof. This is done with ropes and pulleys and hard work.
This was interesting to watch.
Even this passer-by was wondering about the rigging.
An assist from the landlord.

All smiles now.
