As an urban horticulturalist, I wondered exactly the same thing. Also, why did they choose that particularly unusual color of purple?
Reclaiming Water With Purple Pipe | Plumbing & Mechanical
“A graywater system could add up to 20 percent to the cost of the plumbing system. We are installing a system in a school that uses a 20,000-gallon underground tank where stormwater is collected,” says Bruce Rettig of Merit Mechanical (Newark, Del.). Charlotte Pipe’s ReUze CPVC piping is specified for this school project.
What is recycled water?
Recycled water has been treated to remove contaminants, which allows it to be used for irrigation, agriculture, and industrial purposes. On the other hand, advanced purified water, a form of recycled water, is secondary treated wastewater that has been further purified using advanced purification technologies.
What does a purple pipe mean?
Currently, recycled water is distributed through the countywide purple pipe system to recycled water customers. Every time you spot a purple pipe, you can be sure recycled water is flowing through it! Similarly, when you see a purple recycled water sign, it shows that recycled water is used at that location for a specific purpose.
Why is recycled water important in Santa Clara County?
Using recycled water provides many benefits for residents and visitors of Santa Clara County, such as reducing the need for imported water, which helps the environment and decreases water waste. Using recycled water means that we will use less water from our rivers, streams, and groundwater basins. We can maintain healthy ecosystems as well as maintain a reliable, locally controlled water supply that is not reliant on the Sierra snowpack. This helps address the severity of droughts and the impacts of climate change by providing solutions that are sustainable, now and into the future.
What is advanced purified water?
Advanced purified water has gone through an advanced, multi-stage treatment process – microfiltration, reverse osmosis, and ultra violet light disinfection – at the SVAWPC. The blended, enhanced recycled water is used for irrigation, agriculture, and industrial purposes, which helps to reduce the demand for drinking water that would have otherwise been used. Currently, recycled water is distributed through the countywide purple pipe system to recycled water customers. Every time you spot a purple pipe, you can be sure recycled water is flowing through it! Similarly, when you see a purple recycled water sign, it shows that recycled water is used at that location for a specific purpose.

What is the purple pipe called?
Lewinger has become a bit of a legend in the water industry, where he is sometimes asked during water works tours and events to share his story of the purple pipe — which some refer to as “Irvine Purple.”
Why were there only so many colors of plumbing codes?
There were only so many colors left available under the Uniform Plumbing Code, because many were already taken, Holliman recalls . “There was blue for drinking water, red for firefighting, and brown — well, that sends the wrong message.”
What was used to identify recycled water lines?
Prior to the purple pipe, recycled water lines were identified with tape or wire.
Which water district adopted the color?

What are treatment plant piping systems made of?
Though modern treatment plant piping systems are made of different materials, metal remains one of the most common options. Metal pipes can be made of stainless steel, cast iron, copper, brass, or different alloys. The characteristics of individual metals or alloys, the type of fluid or gas flowing through the pipeline, and the environmental conditions must be carefully assessed prior to selecting protective coatings for specific piping systems. In addition, the treatment plant piping systems must comply with all applicable safety guidelines to ensure the safety of plant personnel.
What should stenciled markings include?
Stenciled markings should include numbers along with flow abbreviations and arrows to indicate the flow direction where necessary (e.g. in areas where pipes pass through walls, at intersections, etc.).
Do all water treatment plants follow the same color code?
Though standard piping color codes have been developed for water and wastewater treatment plants, not all plants follow the same recommendations, causing a great deal of confusion.
Do you write the name of the substance on a pipeline?
Additionally, the name of the substance should be written on the pipeline. When different coating systems are used, it’s important to choose a uniform color. Appropriate stenciled marking should be used in conjunction with color coding standards.
Introduction
Reclaimed water systems typically reuse greywater, commonly defined as wastewater from bathtubs, shower drains, sinks, washing machines, and dishwashers. Greywater often accounts for 60% of the outflow produced in homes.
Materials
Certain CPVC , PEX , PE-RT, and PP pipe and fitting systems are intended for reclaimed water systems and may contain special color codes or markings on the products to indicate this application. Piping products intended for reclaimed water are typically purple in color.
Applications
Be sure to consult your local regulations and the pipe and fitting manufacturer when selecting any piping systems for reclaimed water systems. Codes can vary significantly from location to location.
Advantages
CPVC, PEX, PE-RT and PP pipe and fitting systems intended for reclaimed water systems have all the same advantages of installation, cost, and durability as when using these products for potable hot-and cold-water plumbing systems.
Why should pipe labels be placed on either side?
Obstructions to the Label– If a pipe goes through a wall or around a corner, labels should be placed on either side so that people can see the color of the label from any angle.
What is the most important aspect of a pipe label?
The color of pipe markings is typically the most important and visible aspect of the label, but it is not the only one. ANSI also has standards regarding how large a pipe marking label should be and the size of the lettering on the label. This is especially important when creating custom labels for a facility.
Why do you need to put a label on a pipe?
It is also important to add a label if the pipe changes direction so that it is clearly visible. Obstructions to the Label – If a pipe goes through a wall or around a corner, labels should be placed on either side so that people can see the color of the label from any angle.
What color label is used for fire quenching fluid?
Red with White Lettering – This red label with white letter ing is used for all fire quenching fluids. This could include water, but only if the pipe is used just for fire quenching. Orange with Black Lettering – Orange labels with black lettering are for toxic or corrosive fluids.
Why is it important to use user defined pipe markings?
This is important because it allows facilities to plan out certain pipes that don’t fit in with the normal standards. It is important to remember, however, that whenever using user-defined pipe markings, people who haven’t been sufficiently trained won’t know what they mean.
What does the yellow with black on a pipe mean?
Yellow with Black Lettering – This option is used for any pipe that contains flammable liquids and gasses. This could include gasoline, oils, and many others. Green with White Lettering – Using a green label with white lettering means that the pipe contains potable water.
Why are pipe markings covered in dust?
In industrial facilities, pipe markings can get covered in dust, grease, and other contaminants over time, especially if pipes are located in out-of-reach areas such as near the ceiling. Having pipes cleaned on a regular basis will make labels easy to see.
What is purple pipe?
The purple pipe keeps recycled water separate from other types of water delivery systems, such as drinking water and waste water infrastructures. Besides cities and home owner associations, some large tree and shrub nurseries recapture, treat, and reuse their recycled water on their crops and landscape plantings. So, is recycled water the same as gray water?
Where do all these purple pipes go?
Where do all these purple pipes go? A great deal of irrigation water is necessary to keep California landscape green. You can find these purple pipes at sites such as freeways, industrial processes, flushing toilets in some office buildings, and even in cooling towers.
Can you tap into purple pipes?
Can you just tap into these purple pipes to help reduce your impact on our supply of available drinking water? The answer is unfortunately, ‘no’. But maybe not for long if Solana Beach’s Dave Ferguson has the final word. He lives just 6 inches from an exposed purple pipe that irrigates the iceplants surrounding his home. City and county officials say it cannot be done for a sundry of different and unclear reasons. Yet, in the City of Irvine a Free Recycled Water station is ready to meet Irvine citizen’s irrigation needs. Bring your jug, your identification, and you are ready to lug that stuff to a thirsty water saving plant. Not quite the straw to your landscape, but definitely one step closer. Pretty cool, huh? According to the IRWD website, “hundreds of residents have benefitted from the resource.”
Is there a challenge to limit water usage in Los Angeles?
It’s already a challenge to limit water usage as a Los Angeles resident. Now we’re aware that the water delivered through these purple pipes must be carefully considered too, making creativity even more challenging (though much more rewarding when a solution/application is reached). Recycled water is available to irrigate our residential landscapes, yet we’re unable to tap into that delivery system to keep our landscapes healthy and productive is disturbing.
Is purple water potable?
Water from the purple pipe is different than gray water. Both are not potable, but recycled water is cleaner and safer than gray water, which comes with more restrictions on its usage according to cities using recycled water. The City of Palo Alto determined that recycled water is much saltier than drinkable water. When residents started irrigation with water from purple pipes, it clearly damaged the sensitive roots of Azaleas, Buxus, Taxus, Liquidamber, Citrus, Camellias, and Rhododendron. Do you see a pattern here?
Does purple pipe cause high salinity?
The areas tested also had a faulty irrigation system, but where it was somewhat working the soil report showed very high salinity. Since it is close to the beach, the salt water table is higher. But these statistics were off the chart. That said, the purple pipe contributes to a higher than normal alkalinity
