RESIDENTIAL PLUMBING SYSTEMS (WATER SUPPLY)
The Romans are well known for their public water supply and waste water systems. However, except for the wealthy, most access points to the systems were located outside of buildings.

Aqueducts transported water from water sources through lead pipes to limited users
The highest quality water was use for drinking fountains while lower quality water was used in public baths and latrines.

STORAGE TANK
Water is pumped to storage to tanks to be stored until needed. Most storage tanks are elevated to create one pressure in the distribution system. Pressure is measured in psi (pounds per square inch). 1 psi = 2.31 feet

DISTRIBUTION TANKS
Water distribution pipes are created from the following materials:
Reinforced concrete
Thermoplastic
Ductile Iron
In older systems distribution pipes were made from cast-iron or asbestos cement.

PLUMBING PLAN
Plumbing plans are used to show the location of the water supply, vent, and drain lines but may also include storm water drains and gas lines. Note the difference in the line types. Color has been used here to better differentiate between the various lines; however, most plumbing plans will be black and white. The line style is used to differentiate the various types of pipe. Be sure to record the line style and color of each pipe. You will need this information for the next activity.
This plumbing plan was created with Revit software. New detail line styles were defined.
