Dual piping (water)

From Wikipedia, the free encyclopedia

Dual piping is a system of plumbing installations used to supply both potable and reclaimed water to a home or business. Under this system, two completely separate water piping systems are used to deliver water to the user. This system prevents mixing of the two water supplies, which is undesirable, since reclaimed water is usually not intended for human consumption.

In the United States, reclaimed water is distributed in lavender (light purple) pipes, to alert users that the pipes contain non-potable water.
