A purple pipe is used to deliver recycled (or reclaimed) water for non-drinking purposes, like flushing toilets, washing clothes, and watering gardens, separate from the main drinking water supply, preventing contamination and conserving fresh water. The distinct purple color identifies it as non-potable, with specific purple taps and "Do Not Drink" signs ensuring it's not mistaken for tap water.
Oftentimes recycled water can be used as a substitute for potable water. California's plumbing code mandates that recycled water flow through purple pipes. Many of your schools have either already installed purple pipes or they are currently doing so.
