The diameter of a water supply pipe varies depending on its location within the water distribution system.
Water Main Diameters
Water mains, the large pipes that carry water from treatment plants to neighborhoods, typically have larger diameters. According to the provided reference:
-
Common Range: The most common diameters for water mains range from six to 16 inches.
-
Larger Pipes Near Source: You'll often find water mains with larger diameters, such as 12, 14, and 16 inches, closer to the source of the water supply. These larger pipes are used to move greater volumes of water.
-
Smaller Pipes Distal: Pipes with diameters closer to the 6-inch range are typically located further away from the water source.
Diameter Variations in Distribution Network
While the reference specifies water main sizes, it is important to note that residential and commercial supply lines use different pipe sizes.
-
Residential Supply Lines: Typically range from 3/4 inch to 1 inch in diameter, with 1/2 inch sometimes used within the house for individual fixtures.
-
Commercial Supply Lines: Can range from 1 inch to over 4 inches, depending on the building's size and water usage.
Summary of Water Supply Pipe Diameters
| Pipe Type | Common Diameter Range | Typical Locations |
|---|---|---|
| Water Mains | 6 to 16 inches | Near water sources, distribution networks. |
| Residential Supply | 3/4 to 1 inch | Home service lines. |
| Commercial Supply | 1 inch to over 4 inches | Larger buildings with higher water demands. |
It's crucial to remember that the specific diameter of a water supply pipe is dependent on its function and location within the larger water distribution network.
