RESIDENTIAL PLUMBING SYSTEMS (WATER SUPPLY) Heating Ventilation and Air Conditioning Civil Engineering and Architecture Unit 2 – Lesson 2.3 – Services and Utilities 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. APPLICATIONS OF TECHNOLOGY Project Lead The Way, Inc. Copyright 2010

HOW DO WE USE WATER IN OUR HOMES? Heating Ventilation and Air Conditioning Civil Engineering and Architecture Unit 2 – Lesson 2.3 – Services and Utilities HOW DO WE USE WATER IN OUR HOMES? Bathing Toilets Cleaning Food preparation Cooling Fire protection Drinking water = Potable water The Romans are well known for their public water supply and waste water systems.

Heating Ventilation and Air Conditioning Civil Engineering and Architecture Unit 2 – Lesson 2.3 – Services and Utilities WATER SUPPLY SYSTEM 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.

Heating Ventilation and Air Conditioning Civil Engineering and Architecture Unit 2 – Lesson 2.3 – Services and Utilities WATER SUPPLY SYSTEM 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 Project Lead The Way, Inc. Copyright 2010

Heating Ventilation and Air Conditioning Civil Engineering and Architecture Unit 2 – Lesson 2.3 – Services and Utilities 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. Project Lead The Way, Inc. Copyright 2010
