The document provides information about plumbing systems in buildings. It defines a plumbing system as a system of pipes, drains, fittings and devices installed in a building for distribution of water and removal of wastewater. It then lists the common types of pipes used - galvanized iron pipes, cast iron pipes, unplasticized PVC pipes, and rigid PVC pipes - along with their typical diameters and properties. Finally, it describes the two main types of water distribution systems - gravity distribution systems that rely on an elevated water source, and pump and storage systems that use pumps to move water to overhead tanks.

4. Water Distribution System
Gravity Distribution By means of Pump and Storage
It is possible when source is lake or
impound reservoir at some elevation
Example- Hampi, Karnataka( source- Wikipedia)
Water is pumped in overhead tanks
and Reservoirs.
Example- Kutch, Gujarat( source- Tradeindia)
